In this thesis, we present a graphical computer-aided design (CAD) environment for the design, analysis and layout of printed electronic batteries in the first phase and the parasitic extraction of the connecting wires in the second phase. The primary motivation of our work is that this prototyping software tool so far does not exist. Our tool has been integrated within the existing CAD tool which allows quick prototyping and simplifies the interface between the system designer and the device manufacturer. This tools supports the schematic and layout entry, rule checking and netlist generation. The first phase of the device synthesis modelling is based on Enfucell printed batteries, by which using the CAD tool, the shape of the battery is optimized and designed to fit the product and is able to simulate the performance during the optimization, whereas the second phase is the parasitic extraction using an extracting tool named fasthenry, which is integrated to our CAD tool to extract unwanted resistance and inductance within the shared wires between the battery and other devices. We believe that the availability of this tool is useful to the CAD community for novel ideas in the circuit design for flexible hybrid electronics.+46764354255, +46722694942

The report illustrates about the digital tools those are used for product development and organizational management (apparel sector). We went to Lectra Sweden AB, DTS solutions AB to search our planned information about those tools. We got some additional information from them as well. We were interested to learn about much software for this but we studied about Lectra Fashion PLM, PISA PDM, and ERP Garp system (CRM, SRM, MRM) as we could manage opportunity to know about them only.For Lectra, we focused on general idea about this software, its different divisions, its working procedure, its advantage to use, its possibility to use for every company. On the other hand, we concentrated on almost similar way of Lectra for PDM, PLM, ERP (CRM, SRM, and MRM).We got different divisions of Lectra, namely- Kaledo, Modaris, Diamino, Optiplan are using for various purposes, like - design, pattern making, marker making, spreading and cutting. On the opposite side of the coin, if companies implement PDM, PLM and ERP system, they can assist to manage the whole business chain very easily for instance- product development, order, purchase, manufacturing, stock/distribution, economy, logistics etcetera. We also knew that it is expensive to buy those software’s and require special skill to operate so it is not prolific to all company.Program: Magisterutbildning i Applied Textile Management

Motivation: As the human genome project progresses and some microbial and eukaryotic genomes are recognized, numerous biotechnological processes have attracted increasing number of biologists, bioengineers and computer scientists recently. Biotechnological processes profoundly involve production and analysis of highthroughput experimental data. Numerous sequence libraries of DNA and protein structures of a large number of micro-organisms and a variety of other databases related to biology and chemistry are available. For example, microarray technology, a novel biotechnology, promises to monitor the whole genome at once, so that researchers can study the whole genome on the global level and have a better picture of the expressions among millions of genes simultaneously. Today, it is widely used in many fields- disease diagnosis, gene classification, gene regulatory network, and drug discovery. For example, designing organism specific microarray and analysis of experimental data require combining heterogeneous computational tools that usually differ in the data format; such as, GeneMark for ORF extraction, Promide for DNA probe selection, Chip for probe placement on microarray chip, BLAST to compare sequences, MEGA for phylogenetic analysis, and ClustalX for multiple alignments. Solution: Surprisingly enough, despite huge research efforts invested in DNA array applications, very few works are devoted to computer-aided optimization of DNA array design and manufacturing. Current design practices are dominated by ad-hoc heuristics incorporated in proprietary tools with unknown suboptimality. This will soon become a bottleneck for the new generation of high-density arrays, such as the ones currently being designed at Perlegen [109]. The goal of the already accomplished research was to develop highly scalable tools, with predictable runtime and quality, for cost-effective, computer-aided design and manufacturing of DNA probe arrays. We illustrate the utility of our approach by taking a concrete example of combining the design tools of microarray technology for Harpes B virus DNA data.

Electronic Design Automation (EDA) tools are today very capable computer programs supporting electronic engineers with the design of printed circuit board (PCB). All tools have their strengths and weaknesses; when choosing the right tool many factors needs to be taken into consideration aside from the tools themselves. Companies need to focus on the product and revenues for a business to be viable. Depending on the knowledge and strengths of the company, the choice of tools varies. The decision should be based on the efficiency of the tools and the functions necessity for the company rather than the price tags. The quality and availability of support for the tools, training costs, how long will it take to put the tool in operation and present or future collaboration partners is equally important factors when deciding the right tool. The absence of experience and knowledge of the current tool within a company is a factor which could affect important operation; therefore it is important to provide training and education on how to use the tool to increase its efficiency. Providing training and education can be a large expense, but avoids changes within and makes the business competitive. The choice of EDA tool should be based on the employed engineer’s current knowledge and experience of the preferred tool. If the employed engineer’s knowledge and experience varies too much, it might be preferable to make a transition to one of the tool by training and education. Product lifecycle management (PLM) is a data management system and business activity management system which focuses on the lifecycle of a product. To manage the lifecycle of a product it is necessary to split the lifecycle into stages and phases for a more manageable and transparent workflow. By overseeing a product’s entire lifecycle there are benefits which affects many areas. PLM greatest benefits for EDA are collaboration across separate groups and companies by working together through a PLM platform, companies can forge strong design chains that combine their best capabilities to deliver the product to the customers. This report is a study on evaluating which EDA suits the company with consideration of the employed engineer’s demands, requests and competence. The interests in PLM made the company suggest a short theory study on PLM and EDA benefits.

Les récentes avancées en biologie des systèmes et en biologie synthétique contribuent déjà au fleurissement d'applications en ingénierie métabolique visant une bioproduction renouvelable de composés chimiques. Nous pouvons entrevoir un futur où des microbes serait conçus à la carte afin de valoriser n'importe quelle source de carbone en n'importe quel composé d'intérêt. Si la route est longue avant l'accomplissement d'un tel objectif, son parcours devrait en être grandement facilité par l'exploitation de méthodes d'ingénierie déjà éprouvées dans d'autres disciplines. On s'attend entre autre à ce que l'utilisation de logiciels de Conception Assistée par Ordinateur (CAO) diminue le temps et l’expertise nécessaires à la construction de voies métaboliques n'existant pas dans la nature. La première partie de cette thèse est dédiée à notre méthode de prédiction de voies métaboliques et à ses implémentations. Nous décrivons tout particulièrement RetroPath2.0, un outil de prédiction de réseaux de réactions mettant l'accent sur les applications de rétrosynthèse, et qui est construit pour être facilement extensible par la communauté. Dans la seconde partie, nous détaillons l'intérêt des biosenseurs intracellulaires pour l'ingénierie métabolique et introduisons SensiPath; une application web qui exploite un outil de prédiction de réactions pour concevoir des circuits métaboliques permettant la biodétection de composés pour lesquels aucun biosenseur direct n'est connu. Dans l'ensemble, cette thèse propose que les outils de bioCAO devraient permettre de révéler la créativité de leurs utilisateurs et encourager l'exploration de nouvelles applicationsAdvances in systems and synthetic biology are fueling our ability to develop successful metabolic engineering applications for the sustainable production of bio-based chemicals. We can envision a future in which designer cells could be engineered to transform any carbon source into any target compound. This daunting task will be achieved by leveraging methods that proved themselves in other engineering disciplines. Among those, the use of Computer Aided Design(CAD) softwares is expected to reduce the amount of time and expert knowledge needed to design de novo metabolic pathways. The first part of this thesis is dedicated to our pathway prediction algorithm and its CAD implementations. Most notably, we will present RetroPath2.0, a versatile reaction network prediction framework focused on retrosynthesis that is built to be easily extensible by the community. In the second part, we will highlight the interest of intracellular biosensors for metabolic engineering and introduce SensiPath, a web application that uses a reaction prediction engine to design biosensing circuits for compounds for which no direct biosensors are known. Altogether, this thesis proposes that bioCAD tools should focus on empowering users’ creativity and encourage them to explore original applications

This thesis seeks to explore the effectiveness or lack thereof of synchronous, collaborative CAD software, and compare the performance of individuals utilizing such software to one another. Two platforms were used, Solidworks and Onshape, in which the latter had both an independent and a synchronous, collaborative option available. 16 individuals who were already familiar with CAD tools participated in the study, with each utilizing one of the prescribed workflows for the entirety of the hour long trial. Video of the participant's faces and onscreen interaction with the software was recorded throughout the duration of a prescribed task, and the video was utilized in the analysis section of this study. An in depth empirical and statistical analysis is subsequently outlined, and is intended to be utilized as a stepping stone to a later study that will correlate the emotional analysis summarized here with another study dedicated to the user interaction with the software.

— Einweisung in den Gebrauch sowie Auslieferung.
Sinkende Vergütungen durch die Krankenkassen, stark zunehmende Versorgungszahlen und die immer schwieriger werdende Gewinnung von Fachpersonal erfordern eine Straffung der Wertschöpfungskette.
Erreichbar ist diese Straffung nur über eine Umgestaltung der zugrundeliegenden Produktionsprozesse. Die Geschäftsführung entschied, innerhalbeines Projektes zu prüfen, ob der Einsatz digitaler Datenerfassungs- und Bearbeitungstechniken einen wirtschaftlichen Vorteil für die künftige Unternehmensentwicklung darstellt.
Dabei sollen künftig die betroffenen Körperbereiche der Kunden individuell durch geeignete 3D-Digitalisiertechnik erfasst, aufbereitet, modifiziert und archiviert und schließlich als Modellvorlagen in einem CAD/CAM-Verfahren durch CNC-Fräsen hergestellt werden.
Für die Orthopädie- und Rehatechnik Dresden GmbH als stark handwerklich geprägtes KMU ist dieses Projekt ein Meilenstein für die weitere Entwicklung, sowohl hinsichtlich des Investitionsbedarfes als auch der Projektorganisation und der Kommunikation der Änderungen im Unternehmen.
Bedingt durch die Art der angebotenen Produkte und Dienstleistungen finden sich im Unternehmen Mitarbeiter, die über hochspezialisiertes Wissens und individuelle Fähigkeiten verfügen. Die hohe Mitarbeiterzahl im den Bereichen Orthopädie-technik und Orthopädieschuhtechnik erlaubt eine Spezialisierung von Mitarbeitern auf einzelne Produktgruppen. Diese ist der entscheidende Wettbewerbsvorteil in einem von starkem Wettbewerbsdruck geprägten Markt. Sie ist sowohl notwendig für den wirtschaftlichen Erfolg als auch für die erfolgreiche Umsetzung der Veränderungsprozesse.
Eine Umgestaltung der Produktion wie Sie im Rahmen dieses Projektes angestrebt wird bedeutet eine tiefgreifende Veränderung des bisherigen Arbeitsumfeldes. Es entstehen neue, spezialisierte Aufgaben, Verschiebungen von Arbeitsinhalten sowie die Notwendigkeit, vermehrt Aufgaben zu delegieren.

When a company creates, rebuilds or develops new or existing workplace facilitates, research has shown such phases are of the most crucial and influential for creating healthy and effective workplaces. To include ergonomic principles in the early planning stages have proven to result in reduced expenses, and an increased ability to make influential contributions. Practitioners of Occupational Health Services (OHS) possess unique knowledge and expertise in the area, thus have potential to be a tremendous resource during the planning and projection of workspace design projects. Encouraging a participatory approach, OHS practitioners are valuable collaborators with end-users and Architects alike. In this study, three-dimensional CAD-tools were explored in order to provide OHS practitioners with methods and tools that enhance their ability to communicate workspace proposals to end-users of new or renewed office environments. Following an exploration process, a proposed design tool; SketchUp, was preceded for Usability testing. Results of the study indicated a considerable degree of applicability to OHS practitioners, despite an expressed desire for a simpler, more learnable interface. The software was believed to facilitate in the process of visualizing and communicating workspace proposals by increasing end-users understanding of the new work environment, including an enhanced ability to relate to and communicate with Architects.

SILEX é um ambiente aberto e integrado que busca auxiliar a concepção de CIs. 0 sistema e composto por ferramentas internas (servidoras de recursos) e ferramentas do usuário (clientes de recursos). O usuário interage com o sistema SILEX através de uma interface gráfica baseada em janelas, ativando os recursos de forma padronizada e consistente. Sendo um sistema de CAD, SILEX e formado por um conjunto de módulos (ferramentas) interdependentes. Cada módulo realiza a sua função e transmite seus resultados. O usuário torna-se cliente de um conjunto de processos que concorrentemente responde as suas requisições. A ideia básica esconder do usuário os procedimentos que não estão diretamente ligados ao projeto, como: configuração e forma de interação do usuário com as ferramentas; formato, conversão e local de armazenamento dos dados. A regularidade na utilização é um dos principais objetivo do sistema, tendo em vista as constantes mudanças na forma de integração e utilização das ferramentas. Novos algoritmos, quando disponíveis, são informados aos usuários e estes decidem da inclusão em seus ambientes de trabalho, não necessitando qualquer mudança de código. O projetista de ferramentas e auxiliado no desenvolvimento e integração pois conta com um conjunto de rotinas, normas de codificação e serviços prestados. As rotinas permitem a integração das ferramentas ao ambiente, enquanto que as normas regulam a utilização dos recursos disponíveis. A utilização dos recursos dá-se pelo envio de requisições ao servidor do sistema. Os dados gerados pela interação com as ferramentas estão ligados a um projeto, inicialmente definido e cadastrado. Estes são manipulados por uma ferramenta dedicada, que realiza a leitura, escrita e conversão, liberando as ferramentas do usuário destas tarefas. Centralizados, os dados tem controle de acesso, dependência e versão facilitados. SILEX em sua implementação não se beneficia das facilidades adquiridas com a utilização de um framework comercial, visto que foi totalmente construído sobre uma plataforma Open Windows. O objetivo é inicialmente prover soluções simplificadas e eficazes, que permitam a integração de um conjunto de ferramentas e, subsequentemente, incrementar e expandir a fim de que o SILEX tenha todas as características desejadas e ainda não alcançadas pelos frameworks reportados na bibliografia.SILEX is an open and integrated system built up to aid the design of integrated circuits. The SILEX System is composed of internal resources and user tools (clients of the resources). The user has at his disposal a graphic interface based on the use of windows, activating tools in an uniform and consistent way. The SILEX CAD system is formed by a set of interdependent modules (tools), each one realizing certain function and transmitting data. The designer is client of a set of processes that answer his/her requests. The main idea of the project is to hide from the final user all tasks which are not directly related to the art of design, like format conversion, data storage and maintenance and user interaction with tools. One of the goals of the system is the regularity in its use, for there is always the need to integrate new tools. The user can suply new algorithms that may be included in the working environment without any change in the SILEX code. The system helps tool designers by suplying them with a set of routines, coding rules and resources. The set of routines allows integration of the tool with the system, while the coding rules normalize the use of the available resources. All data generated by the user interaction with the available tools is linked to a Project, previously defined and cataloged. Data is then handled by a dedicated tool performing I/O, responsible for the reading, writing and converting of data among different tools, freeing User Tools from this task. By being centralized, Project Data are controlled regarding access, dependency and versioning. SILEX is completely built on top of the OpenWindows environment. Its goal is to initially provide simple and efficient solutions that allow the integration of a set of tools. Next tasks will be the enhancement of the system so that SILEX acquires all desirable characteristics not yet reached or reported in the literature.

Collaboration has always been critical to the success of new product development teams, and the advent of geographically dispersed teams has significantly altered the way that team members interact. Multi-user computer-aided design (MUCAD) and crowdsourcing are two results of efforts to enable collaboration between geographically dispersed individuals. In this research, a study was done to investigate the differences in performance between MUCAD and single-user CAD teams, in which teams competed to create the best model of a hand drill. This was done across a three-day period to recreate the scenario found in industry. It was found that MUCAD increases awareness of teammates' activities and increases communication between team members. Different sources of frustration for single-user and multi-user teams were identified, as well as differing patterns of modeling style. These findings demonstrate that MUCAD software has significant potential to improve team collaboration and performance. A second study explored a number of potentially significant factors in MUCAD team performance, including leadership, design style, unfamiliar parts, knowledge transfer, individual experience, and team composition. In this study, teams of undergraduate mechanical engineering students worked together to complete tasks using NXConnect, a MUCAD plugin for NX developed at Brigham Young University. A primary finding was that having an appointed leader for a MUCAD team improves performance, in particular when that leader works with the team in creating the CAD model. It was also found that creating a framework to aid in organizing and coordinating the creation of the CAD model may decrease the time required for completion. In the final study, the possibility of using crowdsourcing to complete complex product design tasks was explored. In this study, a process for crowdsourcing complex product design tasks was developed, as well as a website to act as the platform for testing this process. A crowd consisting of engineering and technology students then worked together on the website to design a frisbee tracking device. The crowd was able to collaborate to accomplish some detailed product design tasks, but was not able to develop a complete product. Major findings include the need for more formal leadership and crowd organization, the need for better decision making mechanisms, and the need for a better model for engaging crowd members on a consistent basis. It was also found that crowd members had a greater willingness to pay for the product they developed than individuals who had not worked on the project. Results also show that although crowd members were often frustrated with the collaboration process, they enjoyed being able to work with a large group of people on a complex project.

Since the proliferation of CAD tools, visualizations have gained importance.. They provide invaluable visual feedback at the time of design, regardless whether it is fbi civil engineering or electronic circuit design-layout. Typically dynamic visualizations are produced in a two phase process: the calculation of positions and rendering of the image and its presentation as an animated video clip. This is a slow process that is unsuitable fbr interactive CAD visualizations, because the former two require finite element analysis Faster hardware eases the problem, but does not overcome it, because the algorithms are still too slow. Our MEMS CAD project works towards methods and techniques that are suitable for interactive design, with faster methods. The purpose of this PhD thesis is to contribute to the design of an interactive virtual prototyping of Micro Electro Mechanical Systems (MEMS) This research comprises the analysis of the visualization techniques that are appropriate for these tasks and identifying the difficulties that need to be overcome to be able to offer a MEMS design engineer a meaningful and interactive CAD design environment Such a VR-CAD system is being built in our research group with many participants in the team. Two particular problems are being addressed by presenting algorithms for truthful VR visualization methods: one is for displaying objects that are different in size on the computer screen. The other is modelling unsynchronized motion dynamics, that is different objects moving simultaneously at very high and vety low speed, by proposing stroboscopic simulation to present their dynamics on the screen They require specific size scaling and time scaling and filtering. It is these issues and challenges which make the design of a MEMS CAD tool different from other CAD tools. In the thesis I present algorithms for displaying animated virtual reality for MEMS virtual prototyping in a physically truthful way by using the simulated stroboscopic illumination to filter animated images to make it possible to show unsynchronized motion.. A scaling method was used to show or hide objects which cannot be shown simultaneously on the computer screen because of their large difference in size. The visualization of objects being designed and their animations is done with much consideration of visual perception and computer capability, which is rising attention, but not too often mentioned in the visualization domain.

Mestrado em Design de ProdutoA incorporação da área da tecnologia informática no design de produto provocou uma verdadeira revolução em todas as etapas do processo projectual, tornando-se difícil falarmos de design de produto sem nos referenciarmos com as tecnologias CAD. Estas são hoje um precioso auxílio ao designer no desenvolvimento do produto, não só na fase de projecto como nas fases sequentes obrigatoriamente relacionadas – a engenharia, a produção, o marketing, a gestão. No entanto, mais do que um mero auxílio o CAD afigura-se com capacidades de estabelecer uma lógica própria na prática projectual, com potencialidades para se tornar num verdadeiro gestor de todo o processo. De modo a explorar esta hipótese, as metodologias adoptadas foram, numa primeira fase, a elaboração de uma crítica literária, e numa segunda fase foram efectuados estudos de caso a três empresas portuguesas e a uma universidade de ensino superior público. Foi realizada uma análise dos resultados, que verificaram a nossa hipótese e levou às conclusões e a recomendações para futuras investigações. É essencial que o designer se aperceba das potencialidades das tecnologias informáticas, tanto ao nível dos sistemas CAD como a outros sistemas informáticos a jusante do projecto, de modo a poder dialogar com todos os intervenientes no processo numa concepção holística. Além do mais, é fundamental que as tecnologias CAD suportem um papel importante na coordenação de processos, produtos e conhecimentos.
ABSTRACT: The incorporation of computer technology in product design caused a true revolution in all the stages of the design process, where it is almost unthinkable to talk about product design without mention CAD technologies. These are today a precious aid to the designer in product development, not only in the project but in every parts related – engineering, manufacturing, marketing and management. Though, more than just an aid, CAD seems capable to establish his own logic in the project practice, with potential to become a true manager of the whole process. In order to explore this hypothesis, the research methods used were, in a first phase, the literature review, and in a second stage there were made case studies to three different Portuguese companies and to one public higher education university. We performed an analysis of the findings, which verified our hypothesis which leaded us to the conclusions and to future research directions. It is essential that the designer takes awareness of the importance of the computer technologies, both at the level of the CAD systems as other computer systems downstream of the project, in order to be able to dialogue with all the stakeholders in the process in a holistic conception. It is also essential that CAD technologies assume an important role in the coordination of processes, products and knowledge.

Since the proliferation of CAD tools, visualizations have gained importance.. They provide invaluable visual feedback at the time of design, regardless whether it is fbi civil engineering or electronic circuit design-layout. Typically dynamic visualizations are produced in a two phase process: the calculation of positions and rendering of the image and its presentation as an animated video clip. This is a slow process that is unsuitable fbr interactive CAD visualizations, because the former two require finite element analysis Faster hardware eases the problem, but does not overcome it, because the algorithms are still too slow. Our MEMS CAD project works towards methods and techniques that are suitable for interactive design, with faster methods. The purpose of this PhD thesis is to contribute to the design of an interactive virtual prototyping of Micro Electro Mechanical Systems (MEMS) This research comprises the analysis of the visualization techniques that are appropriate for these tasks and identifying the difficulties that need to be overcome to be able to offer a MEMS design engineer a meaningful and interactive CAD design environment Such a VR-CAD system is being built in our research group with many participants in the team. Two particular problems are being addressed by presenting algorithms for truthful VR visualization methods: one is for displaying objects that are different in size on the computer screen. The other is modelling unsynchronized motion dynamics, that is different objects moving simultaneously at very high and vety low speed, by proposing stroboscopic simulation to present their dynamics on the screen They require specific size scaling and time scaling and filtering. It is these issues and challenges which make the design of a MEMS CAD tool different from other CAD tools. In the thesis I present algorithms for displaying animated virtual reality for MEMS virtual prototyping in a physically truthful way by using the simulated stroboscopic illumination to filter animated images to make it possible to show unsynchronized motion.. A scaling method was used to show or hide objects which cannot be shown simultaneously on the computer screen because of their large difference in size. The visualization of objects being designed and their animations is done with much consideration of visual perception and computer capability, which is rising attention, but not too often mentioned in the visualization domain.Thesis (PhD Doctorate)

Este trabalho propõe e avalia uma nova abordagem para projeto de circuitos dedicados utilizando matrizes pré-difundidas. A principal vantagem desta abordagem, denominada Marcela, reside na decomposição lógica do circuito a ser implementado em termos de primitivas disponíveis na matriz escolhida. Aplicando-se tal procedimento, alcança-se grande flexibilidade em termos de posicionamento e roteamento, levando a uma melhor taxa de ocupação. Primeiramente, é feito um levantamento das abordagens para pré-difundidos correntemente encontradas e uma taxonomia baseada nas características mais relevantes é definida. As principais características da metodologia TRANCA são também mostradas. Leiautes gerados com os módulos TRAMO e TRAGO são analisados e algumas modificações na metodologia são sugeridas, visando uma exploração mais eficiente dos dois níveis de metal. As bases para o desenvolvimento da abordagem Marcela são então descritas. A abordagem consiste de uma nova arquitetura para pré-difundidos e uma estratégia específica de ocupação. As principais características da matriz de propósito geral Marcela, primeira a ser definida, são a ausência de canais de roteamento, com as conexões sendo realizadas sobre as células, e a utilização de quatro tipos de células básicas, cada uma dedicada à implementação de uma função lógica primitiva. As células básicas estão organizadas em unidades básicas, as quais são repetidas regularmente para formar a matriz, numa abordagem denominada mar de células. O problema do assinalamento de células e suas particularidades são solucionados utilizando-se uma combinação entre alocação sequencial e técnicas de particionamento. Primeiro, é alocada a mínima superfície da matriz capaz de comportar o circuito em questão, numa fase chamada pré-assinalamento. Na fase de otimização, partições são geradas respeitando a integridade das unidades básicas e trocas de células são realizadas entre os blocos de cada nova partição, em dois passos: trocas individuais, enquanto o bloco de destino não estiver cheio, e trocas de pares. Para o roteamento, foi desenvolvida no CPGCC/UFRGS uma ferramenta específica para ser utilizada em leiautes gerados segundo a metodologia TRANCA. Esta ferramenta, denominada MARTE [JOH 92a][JOH 92b], emprega o algoritmo de Lee básico com algumas modificações, tal como a geração de doglegs para trocas entre trilhas adjacentes. Com a finalidade de validar a abordagem, foram implementados alguns circuitos utilizando a abordagem Marcela e uma abordagem sea-of-gates tradicional. Para circuitos pequenos, tal como um flip-flop D, Marcela produziu uma melhor distribuição de conexões, a qual resulta em aumento da transparência. Porém, a taxa de ocupação encontrada foi menor do que a do circuito projetado com sea-of-gates. Por outro lado, para circuitos de complexidade maior, a área ocupada pode resultar bem menor do que no caso de se usar sea-of-gates, desde que sejam realizadas transformações lógicas apropriadas sobre a descrição equivalente Marcela ou uma matriz conveniente seja escolhida. Exemplos de leiautes desenvolvidos mostram que taxas de ocupação tão altas quanto 75% são atingidas. Finalmente, da observação de circuitos gerados automaticamente, foram tiradas conclusões sobre modificações na arquitetura da matriz e nos algoritmos, de forma a melhorar as taxas de ocupação para qualquer tipo de circuito.This work proposes and evaluates a new approach for the design of ASICs using prediffused masterslices. The main advantage of this approach, called Marcela, relles on logic decomposition of the circuit to be implemented into the chosen masterslice available primitives. By applying this procedure, a great placement and routing flexibility is achieved, thus leading to a better transistor utilization rate. First, a survey on current prediffused approaches is done and an specific taxonomy is defined based on the main important features encountered. Also the main features of TRANCA methodology are shown. Layouts generated using TRAGO and TRAMO modules are analyzed and some modifications in the methodology are suggested, in order to better exploit both first and second metal layers. Marcela approach development basis are described. The approach consists of a new prediffused architecture and an specific occupation strategy. The main architectural features of the general purpose Marcela masterslice are the absence of routing channels, with the connections running over the cells, and the utilization of four types of basic cells, each of them dedicated to perform one primitive logic function. Basic cells are organized into basic units, which are spread a11 over the masterslice, in a so called sea-of-cells approach. The assignment problem and its peculiarities are solved by using a combination of sequential cell allocation and quadrature partition techniques. But first of all, a minimum masterslice area is allocated in a phase called preassignment. In the optimization phase, partitions are generated respecting basic units integrity and cell interchanges are applied to each new partition, following two steps: individual changes, while the target block is not, full. and pairwise interchange. For the routing problem, an specific tool has been developed at CPGCC/UFRGS for any module generator in which TRANCA methodology is applied. This tool, called MARTE [JOH 92a][JOH 92b], employs a basic Lee algorithm with some modifications as dogleg generation for changes between adjacent tracks. In order to validate the approach, some circuits have been implemented using a traditional sea-of-gates and Marcela approaches. For small circuits, as a D flip-flop, Marcela approach has produced a better wiring distribution, which results in increase of transparency. But the occupation rate was found to be smaller than that of the sea-of-gates approach. On the other hand, for more complex circuits the amount of used area can be smaller than that of sea-of-gates case, since appropriate logic transformations are applied to the Marcela logic equivalent or a well suit masterslice is used. Implemented examples show that utilization rates as high as 0.75 are achieved. Finally, from the observation of automatically generated layouts some modifications in masterslice architecture and in the algorithms are figured out.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, NevadaConformal printed antennas of arbitrary shape are used for telemetry applications on high velocity vehicles due to their small size and light weight. The design of these antennas is difficult, however, since there are few accurate analytical models that take the effects of curvature into account. This paper discusses a computer aided design (CAD) tool for arbitrarily shaped printed antennas on cylindrical structures based on a rigorous analytical model. The tool is combined with a graphical user interface and can help antenna designers achieve close to optimal performance. An overview of the mathematical model is given here and the CAD tool is used to highlight the effects of curvature on printed antenna performance. Methods of obtaining circular polarization are reviewed.

Even though Computer Aided Design (CAD) tools have changed the way designers work in most parts of the design process, designers still mostly use pen-and-paper sketching when generating design ideas. Previous studies exploring the use of CAD tools for design ideation have concluded that the tools available at the time did not support reflective conversation, serendipitous interpretation and creativity, making them unsuited for design ideation. However, many of these studies used tools now considered obsolete, implying that the conclusions might no longer be valid. With the variety and capabilities of current CAD tools, there is an opportunity for a new exploration of CAD tools in design ideation. The aim of this licentiate thesis was to explore the use of CAD tools as externalization media in design ideation, what effect this has on the ideation process and how CAD tools might support design ideation. To this end, the thesis explored the use of CAD tools in design ideation in four studies. The first study consisted of a literature review on the strengths and weaknesses of sketches and CAD tools and a focus group discussion with three design experts. The second study compared master theses to explore how design representations used in the design process affect the breadth of design space exploration. The third study was a case study with two cases featuring the use of game engines and Virtual Reality for automotive lighting design and the fourth study compared the workflow in VR-sketching and pen-and- paper sketching. The results of the studies in this thesis suggest that the notion that CAD tools are not useful for design ideation is no longer true. Based on expert evaluations and case studies, this thesis concludes that there are several opportunities for the use of CAD tools in design ideation. This is certainly true in design fields where it is difficult to make sketches. The potential strengths of using CAD tools for design ideation includes the ability to design in full scale and the ability to perform instantaneous transform operations, such as scaling and deforming. However, the ability to instantly undo in CAD tools has been identified as both a potential strength and potential a weakness for design ideation. While being able to rapidly undo mistakes could be beneficial to the ideation process, achieving a faster workflow with less time redoing and more time working on creating, this might also result in fewer opportunities for reinterpretation. The conclusions in this thesis provide arguments for the use of CAD tools in design ideation, which could lead to new ways of generating, working with and thinking about design ideas. The findings also act as a stepping stone for further studies in the area of Computer Aided Ideation.

In this thesis, will be presented BioCAD, a novel computational tool able to design optimal and robust biological circuits. In BioCAD, the main idea is to use Pareto optimality and the Electronic Design Automation methods for Systems and Synthetic Biology.
However, BioCAD is a general purpose tool and can be seen as well as a black box able to receive in input a generic model and analyze its components and submodules, estimate its parameters, or optimize specific functions. BioCAD implements novel and state-of-the-art algorithms performing: (i) Optimization, by analyzing continuous, discrete or hybrid (continuous and discrete) variable spaces, for Single- and Multi-objective optimization problems and for local or global search; (ii) Sensitivity Analysis, for evaluating the importance of the parameters by ranking them according to their influence on the model; (iii) Robustness Analysis, for estimating the global and local fragility and robustness of optimal synthetic circuits; (iv) Identifiability Analysis, that finds functional relations among parameters, by analyzing the values of the decision variables after and before the optimization. Additionally, BioCAD implements the epsilon-dominance analysis, able to relax the Pareto condition and expand the solution space to neighborhood region of the Pareto surface. Optimization core contains novel tools for engineering enzymes, genes and fluxes in biological systems, while Sensitivity Analysis can reveal the main genes, enzymes, species or pathways.
BioCAD can be adopted and used with various modeling techniques: flux balance analysis with or without the gene protein reaction mappings, ordinary differential equations, differential algebraic equations and partial differential equations.
In this thesis will be reported several experiments applied on Synthetic Biology, such as the design of the novel 1,4-butanediol synthetic pathway.

This research presents a new method for integrating client server architectures that are used for the development of Massive Online Role Playing Games (MMORPG) into multi-user engineering software tools. The new method creates a new architecture named CAx Connect by changing the client-pull-server communication pipeline to a server-push-client communication pipeline, effectively reducing the amount of bandwidth consumed and allowing these tools to utilize multiple server processors for complex calculations. This method was used on the new NX Connect multi-user CAx prototype developed at BYU. The new method provides a road map to further implement this architecture and its services into additional multi-user CAx tools. To demonstrate the effectiveness of this technology, a prototype architecture was built to provide a front end service, a message relay service, and a database insertion service, which were integrated into the current architecture. The front end service provides load balancing of clients, while the feature administration service passes messages throughout the architecture. The database insertion service inserts features passed from the NX Connect client into the database. The results show that this architecture is more efficient and that a scalable architecture was created, successfully demonstrating the integration of this architecture with multi-user CAx tools.

Engineering aircraft systems is a complex task. Therefore models and computer simulations are needed to test functions and behaviors of non existing systems, reduce testing time and cost, reduce the risk involved and to detect problems early which reduce the amount of implementation errors. At the section Vehicle Simulation and Thermal Analysis at Saab Aeronautics in Linköping every basic aircraft system is designed and simulated, for example the fuel system. Currently 2-dimensional rectangular blocks are used in the simulation model to represent the fuel tanks. However, this is too simplistic to allow a more detailed analysis. The model needs to be extended with a more complex description of the tank geometry in order to get a more accurate model. This report explains the different steps in the developed methodology for combining 3-dimensional geometry models of any fuel tank created in CATIA with dynamic simulation of the fuel system in Dymola. The new 3-dimensional representation of the tank in Dymola should be able to calculate fuel surface location during simulation of a maneuvering aircraft. The first step of the methodology is to create a solid model of the fuel contents in the tank. Then the area of validity for the model has to be specified, in this step all possible orientations of the fuel acceleration vector within the area of validity is generated. All these orientations are used in the automated volume analysis in CATIA. For each orientation CATIA splits the fuel body in a specified number of volumes and records the volume, the location of the fuel surface and the location of the center of gravity. This recorded data is then approximated with the use of radial basis functions implemented in MATLAB. In MATLAB a surrogate model is created which are then implemented in Dymola. In this way any fuel surface location and center of gravity can be calculated in an efficient way based on the orientation of the fuel acceleration vector and the amount of fuel. The new 3-dimensional tank model is simulated in Dymola and the results are compared with measures from the model in CATIA and with the results from the simulation of the old 2-dimensional tank model. The results shows that the 3-dimensional tank gives a better approximation of reality and that there is a big improvement compared with the 2-dimensional tank model. The downside is that it takes approximately 24 hours to develop this model.Att utveckla ett nytt flygplanssystem är en väldigt komplicerad arbetsuppgift. Därför används modeller och simuleringar för att testa icke befintliga system, minska utvecklingstiden och kostnaderna, begränsa riskerna samt upptäcka problem tidigt och på så sätt minska andelen implementerade fel. Vid sektionen Vehicle Simulation and Thermal Analysis på Saab Aeronautics i Linköping designas och simuleras varje grundflygplanssystem, ett av dessa system är bränslesystemet. För närvarande används 2-dimensionella rätblock i simuleringsmodellen för att representera bränsletankarna, vilket är en väldigt grov approximation. För att kunna utföra mer detaljerade analyser behöver modellerna utökas med en bättre geometrisk beskrivning av bränsletankarna. Denna rapport går igenom de olika stegen i den framtagna metodiken för att kombinera 3- dimensionella tankmodeller skapade i CATIA med dynamisk simulering av bränslesystemet i Dymola. Den nya 3-dimensionella representationen av en tank i Dymola bör kunna beräkna bränsleytans läge under en simulering av ett manövrerande flygplan. Första steget i metodiken är att skapa en solid modell av bränslet som finns i tanken. Därefter specificeras modellens giltighetsområde och alla tänkbara riktningar hos accelerationsvektorn som påverkar bränslet genereras, dessa används sedan i den automatiserade volymanalysen i CATIA. För varje riktning delar CATIA upp bränslemodellen i ett bestämt antal delar och registrerar volymen, bränsleytans läge samt tyngdpunktens position för varje del. Med hjälp av radiala basfunktioner som har implementerats i MATLAB approximeras dessa data och en surrogatmodell tas fram, denna implementeras sedan i Dymola. På så sätt kan bränsleytans och tyngdpunktens läge beräknas på ett effektivt sätt, baserat på riktningen hos bränslets accelerationsvektor samt mängden bränsle i tanken. Den nya 3-dimensionella tankmodellen simuleras i Dymola och resultaten jämförs med mätningar utförda i CATIA samt med resultaten från den gamla simuleringsmodellen. Resultaten visar att den 3-dimensionella tankmodellen ger en mycket bättre representation av verkligheten och att det är en stor förbättring jämfört med den 2-dimensionella representationen. Nackdelen är att det tar ungefär 24 timmar att få fram denna 3-dimensionella representation.

Para entender o problema e as soluções existentes é descrita uma explanação sobre técnicas e algoritmos que são utilizados atualmente ou que são historicamente importantes, de forma a conduzir o texto para as técnicas apresentadas neste trabalho. As técnicas que serão apresentadas neste trabalho têm objetivos individualmente diferentes, porém conduzem a novos resultados e perspectivas em posicionamento. Todas as técnicas são baseadas na modificação e análise do grafo do posicionamento. Neste trabalho serão apresentadas quatro técnicas para melhorar a solução do problema de posicionamento.

A segunda técnica é a Logical Core I, ela traz um novo método de análise da dificuldade de posicionar um circuito VLSI. A terceira técnica, que tem forte conexão com a segunda, é a Logical Core II, mais focada em tempo de execução da técnica, ela gera um vetor com todas as dificuldades de posicionar cada célula no circuito. As duas técnicas aumentam o conhecimento do posicionador a respeito do problema e com isso vão de encontro a um ponto muito importante e ainda pouco abordado, a evolução da controlabilidade no posicionamento. A quarta técnica que será apresentada é a Logical Cluster. É uma técnica baseada na Logical Core II, e foi desenvolvida para otimizar os posicionadores já existentes no estado da arte. A técnica é muito eficiente e reduz o tempo de execução do posicionamento e muitas vezes reduz o comprimento de fio.This work is focused on placement problem of VLSI circuits. The goal is organize the logic gates reducing the total wirelength that connect them. A non-effective placement assignment will not only affect the circuit performance but might also make it non-manufacturable by producing excessive wirelength. Then the next step in the assembly line, the routing problem could be insolvable. In this work will be presents four differents techniques. The techniques are based on changing the graph to improve the placement results. The first one is the Critical Star that applies some extra nodes and edges to reduce the critical paths. The second algorithm is the Logical Core I which brings a new method to analyze the circuit hardness to place a circuit. The third algorithm is called Logical Core II and the focus is generate a vector with hardness to place each cell in the circuit, and increasing the placer information about the problem. The Logical Core I and II, both improving the possibility to compare the hardnesses, in different abstraction levels, and improve the placement controllability. The fourth algorithm is a fast algorithm, based on use the Logical Core II, it creates an effective clustering technique to improve the state-of-art placers results.

This thesis presents a new method that improves upon the existing approaches to developing collaborative tools. The new method uses automatically inferred and manually recorded design rationale to intelligently filter the information that is shared by a collaborative tool. This represents an improvement upon the existing state of the art in collaborative engineering tools. To demonstrate the viability of the method three collaborative tools were created. The first is a multi-user collaborative design environment tool named SimulPart and built upon the NX CAD package. SimulPart uses the new method to limit the amount of communication required to keep every user in synch during a multi-user co-design session. The second implementation is a visual history tool named VisiHistory that allows designers to watch time lapse videos of the creation of a design that are automatically generated using the new method. The final tool is an intelligent user directory named SmartHelp that uses the new method to allow designers to identify which of their peers have expertise in certain CAD operations. Validation was performed for each of these tools by benchmarking the tool against the leading commercial solution or industry process. The results of the validation showed that the new method does in fact offer a superior collaborative solution as it outperforms the existing tools and methods in several key collaborative metrics. As a result of this work future efforts are encouraged into both improving upon the quality of the inferred design rationale and increasing the functionality of the three tools created using the new method.

Mestrado em Engenharia MecânicaA few years ago drawings were made in the drawing boards and using pencils on vellum. There were no computers helping the designers in the parts modeling. After designing the object, the design was passed to the analysts. The designers and analysts were in constant communication. Nowadays, the designers used Computer Aided Design (CAD) tools in the parts modeling. For application the analysis at the geometries, initially a mesh to approximate the geometries is generated. After this, on the mesh the Finite Element Method (FEM) was applied. In complex engineering design, the generation and manipulation of meshes in FEA was estimated to take over 80% of the overall analysis time. The form to break down the barriers between engineering design and the analysis is with reconstruction the entire process, but at the same time maintaining compatibility with existing practices. Create only one geometric model is the focus of reconstruction process. This geometric model is used in the representation of the geometry, as well as in the analysis, and this concept is designated by Isogeometric Analysis (IGA). In this present work the development of the tools for generate the CAD and calculate the basis function for representation the object are proposed. Initially, the mathematical formulations for Bézier, B-Spline and NURBS, for curves and surfaces are presented. The algorithms developed to generate the curves and surfaces are demonstrated. The IGA and FEM formulation for tridimensional and bidimensional spaces are introduced. In this work, a development of a tools for application this method are proposed. The convergence of the results for FEM and IGA programs are studied and compared to the theoretical values and Abaqus comercial program. The results obtained with IGA formulation converge to the reference values.
Há alguns anos atrás, os objectos eram feitos pelos designers e a criação do desenho era feita com lápis e papel vegetal. Não existiam computadores nos gabinetes de desenho para ajudar na modelação dos objectos. Após o desenho estar concluído este era entregue aos analistas para calcularem a resistência do mesmos quando solicitados por cargas externas. Assim, o gabinete de design e o gabinete de análise estavam em constante comunicação. Nos tempos de hoje os designers utilizam as ferramentas de Computer-Aided Design (CAD) para gerar os objectos, representando assim a geometria original. Por outro lado, os analistas fazem a análise baseada no Método dos Elementos Finitos (MEF). Neste método, inicialmente, gera-se uma malha para fazer a aproximação do objecto e utiliza-se esta malha gerada na análise. A forma de combater esta barreira é a construção de um novo processo de análise, mas ao mesmo tempo manter a compatibilidade com a análise do Método de Elementos Finitos. Este novo método foca-se na geração de um modelo geométrico, sendo este modelo utilizado tanto para a representação da geometria como para a análise. A principal sustentação deste novo método é a utilização das funções de base da criação e representação dos objectos, posteriormente, utilizadas na análise dos mesmos. Este novo conceito é designado por Análise Isogeométrica. Neste trabalho é exposto o desenvolvimento de ferramentas para gerar curvas e superfícies utilizando as formulações de Bézier, B-spline e NURBS. Assim, desenvolveram-se sub-rotinas para calcular as funções de base. Inicialmente apresentaram-se as formulações matemáticas e posteriormente os algoritmos desenvolvidos para a representação das curvas e superfícies. O desenvolvimento de ferramentas de análise para problemas no espaço bidimensional e tridimensional utilizando o Método de Elementos Finitos e a Análise Isogeométrica também é abordado neste trabalho. Para ser mais fácil a sua aplicação, foi desenvolvida um interface. Por fim utilizaram-se problemas e estudaram-se as curvas de convergência dos resultados e compararando-os com as referência analíticas e com o programa Abaqus. Em termos de conclusão, os resultados obtidos com a Análise Isogeométrica convergem mais rapidamente para os valores de referência do que o Abaqus e o programa desenvolvido com base no método de elementos finitos.

Many decades ago, Carver Mead established the foundations of neuromorphic systems. Neuromorphic systems are analog circuits that emulate biology. These circuits utilize subthreshold dynamics of CMOS transistors to mimic the behavior of neurons. The objective is to not only simulate the human brain, but also to build useful applications using these bio-inspired circuits for ultra low power speech processing, image processing, and robotics. This can be achieved using reconfigurable hardware, like field programmable analog arrays (FPAAs), which enable configuring different applications on a cross platform system. As digital systems saturate in terms of power efficiency, this alternate approach has the potential to improve computational efficiency by approximately eight orders of magnitude. These systems, which include analog, digital, and neuromorphic elements combine to result in a very powerful reconfigurable processing machine.

A indústria de microeletrônica tem a sua evolução ditada pela necessidade cada vez maior de integração de circuitos como memórias e processadores, fazendo com que os dispositivos semicondutores sejam cada vez mais miniaturizados. Esta miniaturização implica processos de fabricação cada vez mais complexos, resultando em uma grande variabilidade de parâmetros. O projeto de circuitos analógicos torna-se cada vez mais complexo, pois em geral é altamente suscetível às variações de processo, o que afeta a sua produtividade. Uma das partes mais complexas deste projeto é o dimensionamento dos dispositivos que compõem o circuito, pois o espaço de projeto é altamente não-linear e nem sempre se conhece a localização do seu ponto ótimo. Neste contexto, este trabalho tem como objetivo o desenvolvimento de uma ferramenta para o dimensionamento automático de circuitos integrados analógicos, capaz de lidar com a variabilidade dos parâmetros e visando aumentar a produtividade do circuito gerado. Esta ferramenta baseia-se no dimensionamento do circuito como um problema de otimização baseado em simulação elétrica SPICE. O objetivo principal é receber as especificações requeridas de uma topologia de circuito e, através de técnicas de inteligência artificial, explorar o espaço de soluções em busca de soluções otimizadas que atendam às restrições impostas. Além disso, espera se obter soluções que atendam às especificações requeridas mesmo com variações no processo de fabricação. Para isso, são empregadas técnicas de design centering de modo a maximizar a produtividade do circuito. A ferramenta desenvolvida foi implementada de maneira modular, permitindo que a análise do dimensionamento do circuito possa ser realizada sob diferentes aspectos. Como resultado, este trabalho apresenta duas topologias de amplificadores operacionais automaticamente dimensionadas em tecnologia CMOS, tendo como objetivo a minimização da área de gate e da potência dissipada, além da maximização da produtividade. Os circuitos gerados apresentaram melhor desempenho em comparação com resultados descritos na literatura.
The microelectronics industry has the CMOS technology evolution dictated by the capability of integration of digital circuits such as memories and processors, causing the semiconductor devices miniaturization. The miniaturization leads to complex manufacturing processes with high parameters variation. Analog circuit designs are complex and highly susceptible to process variations, affecting the circuit yield. One of the most complex part of the analog design is the circuit sizing, since the possible solutions have a highly nonlinear design space and the optimal solution is not known. In this context, this work aims at developing a tool for the automatic sizing of analog integrated circuits that is able to deal with parameter variation in order to yield maximization. This tool is based on the circuit sizing as an optimization problem based on electrical SPICE simulations. The main objective is to receive the required specifications of a circuit topology and, by means of artificial intelligence techniques, to explore the design space for optimized solutions that meet the circuit constraints. Furthermore, it is expected to obtain solutions which meet the specifications required even with the presence of variations in the manufacturing process. For this purpose, design centering techniques are implemented for yield maximization. The tool is implemented with modular functions, enabling the sizing process on different configurations. As results, this work present the automatic design of two CMOS operational amplifiers topologies, with the goal to reduce the power dissipation and the gate area and to maximize the yield. The results present good performance when compared to similar designs found in literature.

During a product design and development process, design teams use a variety of tools to generate and represent multiple design options before they eventually arrive at a singular design solution. Studying how these tools can influence the design outcome has the potential to enable designers to become more aware of the choices they make when they choose to use a tool. Because so much of the cost of a product is determined during the early stages of product development, reviewing these design alternatives with stakeholders is a valuable part of the process. Understanding how stakeholders respond to a design representation is vital to interpreting potential user feedback accurately In this dissertation, I investigate these questions about early-stage design process: I. How does the use of a specific design tool influence the design outcome? II. What design attributes do designers associate with these tools? In Part I of this research, designers made sketches, foam model prototypes, or CAD models in a controlled experiment. Followed by a survey of the designs with potential users, Part I demonstrated how different design tools affect the quantity and quality of ideas, including that designs created as prototypes were recognized as more novel, more aesthetically pleasing, and more comfortable to use. In Part II, in a survey of designers with experience in sketching, foam models, and CAD, designs from Part I were re-represented as sketches. Experienced designers exhibited a better-than-random likelihood to identify the original tool used to create the design, despite viewing only the re-sketch. This suggests artifacts of a design tool persist in a design representation despite the design being translated from one medium to another.

Este trabalho trata de pesquisa de soluções para a síntese física de circuitos integrados menos susceptíveis aos efeitos de variabilidade decorrentes do uso de tecnologias de fabricação com dimensões nanométricas. Também apresenta a pesquisa e o desenvolvimento de uma ferramenta para a geração de leiautes regulares denominada R-CAT. A regularidade geométrica é explorada pela repetição de padrões básicos de leiaute ao longo de uma matriz. A regularidade é apontada como uma das melhores alternativas para lidar com os atuais problemas de fabricação em tecnologias submicrônicas. Projetos regulares são menos suscetíveis aos problemas de litografia, aumentam o yield e diminuem o tempo gasto em re-projeto. Além disso, circuitos regulares apresentam maior previsibilidade de resultados de potência, atraso e yield, principalmente pelo fato das células estarem pré-caracterizadas. A ferramenta desenvolvida visa o trabalho com dois tipos de síntese física para leiautes regulares, produzindo circuitos integrados personalizáveis por todas as máscaras ou circuitos personalizáveis por algumas máscaras. O principal objetivo deste gerador é a facilidade de conversão e adaptação dependendo da abordagem de matriz escolhida. Isso facilitará a comparação entre diferentes alternativas de matrizes, a adoção de blocos lógicos diversos e de novas tecnologias. O gerador de leiautes R-CAT identifica células adjacentes com conexões em comum entre elas e realiza a conexão entre essas células em metal 1, reduzindo o número de conexões a ser realizado pelo roteador em até 10%. A ferramenta R-CAT está inserida em um fluxo de projeto e depende do método de síntese lógica adotado. Duas ferramentas de síntese lógica foram utilizadas: SIS e OrBDDs, oferecendo duas linhas de projeto: a primeira priorizando a área e a segunda priorizando timing e interconexões curtas. Ambas respeitando a mesma regularidade geométrica imposta pela matriz. Os resultados obtidos demonstram que as matrizes SIS ocupam 53% menos área do que a estratégia orBDD e reduzem o wire length em 30%. Uma área menor é obtida devido ao fato da ferramenta SIS gerar descrições com a metade de células lógicas e nets. Entretanto, as matrizes R-CAT OrBDD apresentam menor wire length médio, menor fan-out (redução de 15%), menor delay e maior roteabilidade. As sínteses OrBDD apresentam poucas nets não roteadas sem a inserção de trilhas extras. Além disso, as matrizes R-CAT atingiram resultados até 40% menores em wire length e reduções de área de até 46% em relação às matrizes MARTELO.This work presents a research for physical synthesis of integrated circuits, which are less susceptible to the effects of variability observed in fabrication technologies using nanometers scale. Moreover, it presents a CAD tool developed to generate regular layouts, which is called R-CAT. The geometric regularity is achieved using basic patterns repeated along one matrix structure. Regularity is pointed like one of the best alternatives to deal with submicron technologies issues. Regular designs are less susceptible to lithographic problems, improve the yield and decrease the time to re-spin. Furthermore, regular circuits improve predictability of power consumption, timing and yield results, because the cells are pre-characterized. The developed tool focuses on two types of physical synthesis for regular layouts, producing either integrated circuit customized using all masks or integrated circuits customized using some masks. The main goal is the facility of conversion and adaptation depending on the chosen matrix approach. This will make easier the comparison of different matrix approaches, besides the adoption of several logic blocks and new technologies. R-CAT layout generator identifies adjacent cells that are placed in a same row and have common connections between them. In this case, the generator can make these connections in Metal 1. This technique reduces the number of connections to be done by the router. The experiments showed that this technique is able to reduce about 10% the number of connections to be done. This tool is inserted into a design flow and it is dependent of the logic synthesis methodology adopted. Two logical syntheses tools were used in the flow: SIS and OrBDDs. R-CAT SIS and R-CAT orBDD Matrices were generated for a set of circuits. The use of R-CAT tool with SIS and orBDD logical synthesis offers two design lines: the first one highlights area and the second one emphasize timing and short connections. Both of them respect the same geometric regularity. The results demonstrate that SIS matrices present 53% less area than orBDD approach and reduce the wire length by 30%. The area reduction is achieved because the SIS tool generates descriptions with the half of logic cells and nets. Nevertheless, the R-CAT orBDD matrices decreased the medium wire length, reduced the fan-out in 15%, reduced the delay and improved the routability. orBDD synthesis presents few non-routed nets without extra tracks insertion. Moreover, the R-CAT matrices obtained about 40% better results in wire length and they reduced area in 46% when compared to MARTELO matrices.

Resumo: A utilização de técnicas de Fabricação Digital está cada vez mais presente no campo da arquitetura e construção por todo o mundo, devido aos avanços tecnológicos que os sistemas CAD (Computer-aided Design) e CAM (Computer-aided Manufacturing) têm proporcionado aos processos de concepção e produção da obra arquitetônica. As possibilidades que essas ferramentas oferecem aos arquitetos e projetistas abrem caminho para novas abordagens de projeto, que permitem o uso da produção automatizada sem a necessidade de uma padronização tão rígida como aquela imposta pelo sistema industrial. Entretanto, nota-se que a aplicação dos métodos de Fabricação Digital no processo de produção do espaço edificado no Brasil é lento, quando comparado a outros países onde a tecnologia necessária para o exercício da técnica já se encontra amplamente difundida. A presente pesquisa tem como foco investigar a aplicação da Fabricação Digital, por intermédio de processos file-to-factory na produção arquitetônica de elementos para a construção civil, mais especificamente com o uso de técnicas subtrativas de corte 2D. Após um levantamento sobre o estado da arte da área e o desenvolvimento de dois estudos de caso, o método utilizado foi a pesquisa-ação, por meio de um exercício de aplicação do conceito file-to-factory. O processo de projeto foi documentado detalhadamente e analisado para a sistematização dos procedimentos, que servirão de referência para futuras aplicações no campo da arquitetura. Espera-se, com isso, contribuir para a divulgação dessas novas tecnologias na produção arquitetônica no cenário brasileiro
Abstract: The use of Digital Fabrication techniques is increasingly present in the field of architecture and construction throughout the world. Systems such as CAD (Computer-aided Design) and CAM (Computer-aided Manufacturing) have provided technological advances to the architectural design and production process. The possibilities that these tools provide to architects and designers introduce new design approaches, which allow the use of automated production without the rigid standardization imposed by the industrial system. However, it can be noticed that the use of Digital Fabrication methods in the built environment production process in Brazil is slow when compared to other countries where the technology is widely incorporated. This research focuses on investigating the application of Digital Fabrication, through file-to-factory processes in the production of architectural elements for the construction industry, specifically with the use of 2D subtractive cutting techniques. After a survey on the state of the art in the field and two case studies, the method used was an action research through a file-to-factory exercise. The design process was documented in detail and analyzed in order to systematize the procedures as a reference for future applications in architecture. As a result we expect to contribute to the dissemination of these new technologies in architectural production in the Brazilian scenario

Cell-based design is a widely adopted design approach in current Application Specific Integrated Circuits (ASIC) and System-on-Chip (SOC) designs. A standard cell library is a collection of basic building blocks that can be used in cell-based design. The use of a standard cell library offers shorter design time, induces fewer errors in the design process, and is easier to maintain.
Development of a cell library is laborious, prone to errors and even a small error on a library cell can possibly be disastrous due to repeated use of the cell in a design. In this thesis, we investigated ways to automate the process for development of a cell library, specifically TSMC 0.18-micron CMOS standard cell library. We examined various steps in the design flow to identify required repetitive tasks for individual cells. Those steps include physical verification, netlist extraction, cell characterization, and generation of Synopsys Liberty Format file. We developed necessary scripts in Skill, Tcl, Perl and Shell to automate those steps. Additionally, we developed scripts to automate the quality assurance process of the cell library, where quality assurance consists of verifying the entire ASIC design flow adopted for the Virginia Tech VLSI Telecommunications (VTVT) lab. Our scripts have been successfully used to develop our TSMC 0.18-micron library and to verify the quality assurance. The first version of the cell library was released on November 1, 2007 to universities worldwide, and as of March 2008, 20 universities have received the library from us.Master of Science

The scope of this study is to illustrate the relationship between computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, and to show how architectural modeling should be positioned in the process of computer-aided design/computer-aided manufacturing (CAD/CAM) systems. The integration of computer aided technologies with architectural design is investigated in terms of design-production/fabrication interaction. The research has been based on a case study in which the CAD/CAM process from the initial design phase to the actual manufacturing of the design object has been explored. A design object is modeled using CAD and the model is manufactured using CAM in order to illustrate the process of CAD/CAM and its potentials related to architectural design and the construction/manufacturing/fabrication process of building. Thus, the study tries to demonstrate what digital tools can provide to the field of architecture, and lists the requirements for architectural modeling to acquire compatibility among the parts of the building process.

Dissertação apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Arquitetura e UrbanismoA presente dissertação de mestrado pretende abordar a influência das ferramentas digitais durante todo o processo arquitectónico, demonstrando a evolução desde o uso do lápis à utilização da robotização, alterando assim a forma de pensar do arquiteto, não deixando de referir a influência da arte na Arquitetura. Esta mudança de pensamento não é característica apenas dos dias de hoje, sendo visível ao longo da dissertação de que os grandes nomes da aquitetura, também passaram por uma fase de mudança de paradigma, fruto da evolução tecnológica, que levou ao aparecimento de novos estilos e teorias. O paradigma actual reflecte-se na utilização das ferramentas digitais e na forma como elas vão influenciar a Arquitetura dos dias de hoje. A variedade de ferramentas existentes permite que arquiteto explore a sua criatividade, de uma forma mais complexa e precisa. Como exemplo disso foram escolhidos três casos de estudo com o objetivo de demonstrar o desenvolvimento e a utilização das ferramentas digitais e como estas influenciam o arquiteto no processo de desenhar e pensar Arquitetura. Reflete-se no caso do Museu Guggenheim, um dos ícones da Arquitetura Contemporânea, do arquiteto Frank Ghery, sendo perceptível a grande utilização do software (CATIA), como uma ferramenta digital pioneira na Arquitetura. No caso do pavilhão ICD/ITKE, o arquiteto Achim Menges demonstra que o processo de cooperação, entre as várias ciências e as ferramentas origina uma Arquitetura final inovadora, resultante dos mesmos. Finalizando com o caso de estudo da Sagrada Família, um exemplo da utilização das ferramentas no processo de finalização da obra.
This master thesis aims to address the influence of digital tools throughout the architectural process, showing the evolution from the use of pencil to use the robot, thus changing the way of thinking of the architect, not forgetting to mention the influence of art in architecture. This change in thinking is not characteristic only of today, being visible along the thesis that the big names in architecture also went through a phase change of paradigm, the result of technological developments which led to the emergence of new styles and theories. The current paradigm is reflected in the use of digital tools and how they will influence the architecture of today. A variety of existing tools allows architect to explore their creativity in a more complex and accurately way. As an example was set the three case studies in order to demonstrate the development and use of digital tools and how they influence the architect in the process of designing and thinking architecture. It is reflected in the case of the Guggenheim Museum, one of the icons of contemporary architecture, by the architect Frank Gehry, with noticeable great use of the software (CATIA), as a pioneering digital tool in architecture. In the case of ICD / ITKE pavilion, architect Achim Menges demonstrates that the process of cooperation between the various sciences and tools lead to innovative end architecture, resulting thereof. Finishing with the case of the Sagrada Família study, an example of the use of the tools in the work of finalizing the construction process.

Thesis (M. Tech. (Design and Studio Art)) -- Central University of Technology, Free State, 2014This quantitative research project investigates the utilization of emerging technologies within the arts with a view on establishing an interdisciplinary approach between ceramics and engineering. The traditional manufacturing method of producing master moulds is a time-consuming process for the studio ceramicist. This study explores whether computer-aided design (CAD) and computer numerical control (CNC) milling can accelerate the design and manufacturing process when developing master moulds as an alternative to using traditional methods. It investigates whether SolidWorks® can be applied as a suitable CAD design tool for the creation of ceramic vessel forms in order to reduce the design development time frame. It furthermore investigates whether CNC milling can be used as a viable manufacturing technology for the making of vessel prototypes and master moulds from CAD data, the overall objective being to improve and accelerate the plaster of Paris master mould manufacturing process for the batch production of studio-based ceramic artefacts. Findings from this study indicate that emerging technologies have a lot to offer the artist when it comes to providing new possibilities for the creation of artefacts and that SolidWorks® and CNC milling can be utilized as a viable interdisciplinary manufacturing approach between ceramics and digital manufacturing technologies.

Esta pesquisa procura investigar o processo de projeto na arquitetura e como o mesmo passou a ser influenciado nas últimas décadas pelas ferramentas digitais que surgiram desde então. Busca estabelecer uma visão sobre o projeto arquitetônico questionando a existência de um novo paradigma. Para isso analisa a produção acadêmica brasileira dos últimos anos que exploraram ou desenvolveram teorias sobre a utilização de ferramentas digitais afim de estabelecer um ponto de partida. Através da bibliografia expõem uma visão e uma defesa de uma forma de projetar e de como as ferramentas digitais podem auxiliar este processo sem criar deturpações de uso. Por fim o texto contrapõem duas arquiteturas: a arquitetura silenciosa - sóbria - que busca adequar-se à cidade e tão bem aguenta o passar do tempo e a arquitetura digitalista, focada no "inusitado", que está muito mais voltada à possibilidade de exploração midiática da edificação e que tantos problemas traz aos usuários e à sociedade.This research investigates the design process in architecture and how it came to be influenced in the past few years by digital tools which emerged since then. It seeks to establish a vision about the architecture design methods by questioning the existence of a new paradigm. Thereunto it analyzes the Brazilian academic production of the past few years which explored or developed theories about the use of digital tools in order to establish a starting point. Through literature, it exposes a vision and a defense of a way of designing and how digital tools can assist this process without creating distortions of its use. Finally, the text contrasts two types of architecture: the silent, sober architecture, which seeks to adapt to the city and as well support the passage of time and changes of its uses, and the "digitalist" architecture, focused on the "unusual", which turns to the possibility of the media exploitation of the building and the many problems it brings to users and society.
