Abstract:

Software testability parameter system was constructed by parameters that extracted from software testability influence factors. It established relationships between these parameters and software testability through a target layer which may reflect software inner attributes. In order to carry out the design of software testability in engineering ways, principles of software testability requirements and software testability requirement factor were presented in this article, as well as analysis method for software testability requirement. This method considered software characteristics and software test types as selection criteria to specify the target layer, and then tried to acquire software testability requirement factors with the help of software testability parameter architecture built before. Next, software testability requirement could be obtained by following the steps of software requirement engineering.

Abstract:

Requirements for software testability is an important basis of design for software design of testability. During the software-testability-design work, a series of software design for testability measures must be taken to make software testing stage less detours, and formulation and implementation of requirements for software testing is an important element. This paper introduces a kind of develop-method of requirements for software testability. According as causal analysis, basing on manifestations of software testability, the method develops appropriate requirements for software testability for software system. Preface The software testability is referred to as a kind of attribute that aims to facilitate the application test and improve the location and correction of software error [. To a certain extent, the software testability can solve some problems facing the software test, such as helping the designer to develop the software that is easier to test, so as to reduce the test difficulty, save more test time and optimize the resource allocation. Therefore, the software testability has stood out as quite an important factor that has a great effect on the cost, time and labor allocation of software test, which are also closely related to the quality of software engineering [. Since the 1990s, the software testability has been widely concerned by the scholars both at home and abroad. According to the relevant literatures collected, the general research direction has been toward the measurement and analysis of the software testability [. It should be noted that a well developed scheme of the requirement of software testability can not only enhance the testability of the target software, but also serve as the evaluation criterion of the testability, which means that it will have special reference to the improvement on the software test [. Based on the casual analysis, this paper has sought to provide a whole set of the requirement of software testability and come up with a real case so as to approach the design issues of the software testability [. 1 The requirement of software testability

Abstract:

On the basis of conception, the characteristics of current testability indicators allocation methods are analyzed. Due to their shortages, we establish a weighted allocation method based on upper and lower limitation to equipment testability indicators and present the initial value of unit’s testability indicators, upper and lower limitation, adjust means to initial value and whole calculation steps. The illustrated example shows that, by this allocation method, dependence to one’s experience can be decrease to the lowest limitation, control to unit testability indicators’ range is perfect, and we can assign the lowest unit testability indicators’ and their combination to realize system’s testability indicators.

Abstract:

To measure testability before the actual development starts will play a crucial role to the developer, designers and end users as well. Early measurement of testability, especially in early requirement stage to assist the developer for the further development process, and will also assures us to produce and deliver the high quality requirement that can surely reduce the overall cost and improves the quality of development process. Taking view of this fact, this paper identifies testability estimation factors namely understandability and modifiability and establishes the correlation among testability, understandability and modifiability. Further, a model is developed to quantify software testability in requirement phase and named as Requirement Testability Model of Object Oriented Software-RTMOOS. Furthermore, the correlation of Testability with these factors has been tested and justified with the help of statistical measures.

Abstract:

Testability demonstration plays an important role in assuring the testability capability, which can decrease the fault diagnosis time and accelerate the maintenance actions. However, testability demonstration test with classical planning method has the problems of large fault sample size, high test cost, and long test period. A new testability demonstration planning method is proposed, which takes the component level data from both virtual and physical demonstration tests as prior information. Owing to the limitations of the testability modeling technology and relevant programming tools, the virtual testability prototype of the system level cannot be established and the virtual testability test data is not totally credible. So a data conversion method based on the information entropy theory is proposed to convert the component level virtual and physical test data into equivalent system test data, in which the data credibility is taken into consideration. The equivalent system test data is then used to get the prior probability density function of the testability indexes with an empirical Bayesian method. Then, a testability demonstration planning method of Bayesian posterior risk criteria is presented. Finally, the fault detection rate demonstration tests of a flight control system and a heating controller are taken as examples to verify the proposed method. The results show that the introduction of prior test data can effectively decrease the sample size and the credibility of the virtual testability test data can affect the test plan.

Abstract:

The multisensor data fusion method has been extensively utilized in many practical applications involving testability evaluation. Due to the flexibility and effectiveness of Dempster–Shafer evidence theory in modeling and processing uncertain information, this theory has been widely used in various fields of multisensor data fusion method. However, it may lead to wrong results when fusing conflicting multisensor data. In order to deal with this problem, a testability evaluation method of equipment based on multisensor data fusion method is proposed. First, a novel multisensor data fusion method, based on the improvement of Dempster–Shafer evidence theory via the Lance distance and the belief entropy, is proposed. Next, based on the analysis of testability multisensor data, such as testability virtual test data, testability test data of replaceable unit, and testability growth test data, the corresponding prior distribution conversion schemes of testability multisensor data are formulated according to their different characteristics. Finally, the testability evaluation method of equipment based on the multisensor data fusion method is proposed. The result of experiment illustrated that the proposed method is feasible and effective in handling the conflicting evidence; besides, the accuracy of fusion of the proposed method is higher and the result of evaluation is more reliable than other testability evaluation methods, which shows that the basic probability assignment of the true target is 94.71%.

Abstract:

Due to the lack of effective modeling and analysis methods for testability of complex electronic system, a testability index model is established to resolve this problem. First of all, the existing testability demonstration test and evaluation method are analyzed. On this basis, testability indexes statistical models based on the binomial distribution, or Beta distribution and F distribution are established. What’s more, the relationship and principle between the fault detection or isolation data and the confidence level are analyzed in these models. Finally, the result of simulation shows that these models are practical and effective, which provides a new way of effectively analyzing and evaluating testability indexes of complex electronic system.

Abstract:

This paper investigates a type of STGM (system testability growth model) based on the nonhomogeneous Poisson process which incorporates TGEF (testability growth effort function). First, we analyze the process of TGT (testability growth test) for equipment, which shows that the TGT can be divided into two committed steps: make the unit under test be in broken condition to identify TDL (testability design limitation) and remove the TDL. We consider that the amount of TGF (testability growth effort) spent on identifying TDL is a crucial issue which decides the shape of testability growth curve and that the TGF increases firstly and then decreases at different rates in the whole life cycle. Furthermore, we incorporate five TGEFs: an Exponential curve, a Rayleigh curve, a logistic curve, a delayed S-shape curve or an inflected S-shaped curve which are collectively referred to as Bell-shaped TGEFs into STGM. Results from applications to a real data set of a stable tracking platform are analyzed and evaluated in testability prediction capability and show that the Bell-shaped function can be expressed as a TGF curve and that the logistic TGEF dependent STGM gives better predictions based on the real data set.

Abstract:

A digital circuit includes two main parts: a controller and a datapath. After connection of these two parts, both are subject to a sharp fall in testability due to the lack of controllability and observability at the interface. In this paper, we propose a method for specifying the control part in order to restore the testability of the datapath to a level close to the initial one, in other words its testability before connection. This testability driven specification affects the next state logic as well as the decoder part of the controller but does not make use of any scan-based element. Based on the finite automata theory and on results of a testability analysis performed on the datapath, the proposed method entails very little area penalty.

Abstract:

The testability distribution of a VLSI circuit is modeled as a series of step functions over the interval [0, 1]. The model generalizes previous related work on testability. Unlike previous work, however, we include estimates of testability by random vectors. Quadratic programming methods are used to estimate the parameters of the testability distribution from fault coverage data (random and deterministic) on a sample of faults. The estimated testability is then used to predict the random and deterministic fault coverage distributions without the need to employ test generation or fault simulations. The prediction of fault coverage distribution can answer important questions about the “goodness” of a design from a testing point of view. Experimental results are given on the large ISCAS-85 and ISCAS-89 circuits.

Abstract:

Testability should be considered as early as possible in VLSI synthesis and optimization. In most CAD tools, testability preservation is achieved as a by-product of finding a less redundant implementation. Unfortunately, this approach is not supported by theory. It is essential to have an optimization scheme that systematically preserves testability. A complete theory covering testability-preserving optimization of combinational circuits is yet to be developed.In this paper, a new testability-preserving theory is established. This theory covers most optimization cases in the synthesis of irredundant circuits. Optimization of redundant circuits is also considered. Algorithms based on this theory are proposed. Experiments to verify the theory and algorithms are reported. The developed theory and algorithms are more general than previous results.

Abstract:

A locally testable semigroup S is a semigroup with the property that for some non-negative integer k, called the order or level of local testability, two words u and v in some set of generators for S are equal in the semigroup if (1) the prefix and suffix of the words of length k coincide, and (2) the set of intermediate substrings of length k of the words coincide. The local testability problem for semigroups is, given a finite semigroup, to decide, if the semigroup is locally testable or not. Recently, we introduced a polynomial time algorithm for the local testability problem and to find the level of local testability for semigroups based on our previous description of identities of k-testable semigroups and the structure of locally testable semigroups. The first part of the algorithm we introduce solves the local testability problem. The second part of the algorithm finds the order of local testability of a semigroup. The algorithm is of order n2, where n is the order of the semigroup.

Abstract:

This paper describes a methodology based on improved genetic algorithms (GA) and experiments plan to optimize the testability allocation. Test resources were reasonably configured for testability optimization allocation, in order to meet the testability allocation requirements and resource constraints. The optimal solution was not easy to solve of general genetic algorithm, and the initial parameter value was not easy to set up and other defects. So in order to more efficiently test and optimize the allocation, migration technology was introduced in the traditional genetic algorithm to optimize the iterative process, and initial parameters of algorithm could be adjusted by using AHP approach, consequently testability optimization allocation approach based on improved genetic algorithm was proposed. A numerical example is used to assess the method. and the examples show that this approach can quickly and efficiently to seek the optimal solution of testability optimization allocation problem.

Abstract:

Resulting from the short production cycle and rapid design technology development, traditional prognostic and health management (PHM) approaches become impractical and fail to match the requirement of systems with structural and functional complexity. Among all PHM designs, testability design and maintainability design face critical difficulties. First, testability design requires much labor and knowledge preparation, and wastes the sensor recording information. Second, maintainability design suffers bad influences by improper testability design. We proposed a test strategy optimization based on soft-sensing and ensemble belief measurements to overcome these problems. Instead of serial PHM design, the proposed method constructs a closed loop between testability and maintenance to generate an adaptive fault diagnostic tree with soft-sensor nodes. The diagnostic tree generated ensures high efficiency and flexibility, taking advantage of extreme learning machine (ELM) and affinity propagation (AP). The experiment results show that our method receives the highest performance with state-of-art methods. Additionally, the proposed method enlarges the diagnostic flexibility and saves much human labor on testability design.

Abstract:

Design for testability is a very importantissue in software engineering. It becomes crucial in the case of Model Based Testing where models are generally not tested before using as input of Model Based Testing. The quality of design models (e.g.; UML models), has received less attention, which are main artifacts of any software design. Testability tends to make the validation phase more efficient in exposing faults during testing, and consequently to increase quality of the end-product to meet required specifications. Testability modeling has been researched for many years. Unfortunately, the modeling of a design for testability is often performed after the design is complete. This limits the functional use of the testability model to determining what level of test coverage is available in the design. This information may be useful to help assess whether a product meets the target requirement to achieve a desired level of test coverage, but has little pro-active effect on making the design more testable.

Abstract:

Synthesis for testability ensures that the synthesized circuit is testable by exploring the fundamental relationship between don't care and redundancy. With the exploration of the relationship, redundancy removal can be applied to improve the testability, reduce the area and improve the speed of a synthesized circuit. The test generation problems have been adequately solved, therefore an innovative testability synthesis strategy is necessary for achieving the maximum fault coverage and area reduction for maximum speed. This paper presents a testability synthesis methodology applicable to a top–down design method based on the identification and removal of redundant faults. Emphasis has been placed on the testability synthesis of a high-speed binary jumping carry adder. A synthesized 32-bit testable adder implemented by a 1.2 μm CMOS technology performs addition in 4.09 ns. Comparing with the original synthesized circuit, redundancy removal yields a 100% testable design with a 15% improvement in speed and a 25% reduction in area.

Abstract:

Circuits of VLSI complexity are designed using modules such as adders, multipliers, register files, memories, multiplexers, and busses. During the high-level design of such a circuit, it is important to be able to consider several alternative designs and compare them on counts of area, performance, and testability. While tools exist for area and delay estimation of module-level circuits, most of the testability analysis tools work on gate-level descriptions of the circuit. Thus an expensive operation of flattening the circuit becomes necessary to carry out testability analysis. In this paper, we describe a time and space-efficient technique for evaluating the well known SCOAP testability measure of a circuit from its hierarchical description with two or more levels of hierarchy. We introduce the notion of SCOAP Expression Diagrams for functional modules, which can be precomputed and stored as part of the module data base. Our hierarchical testability analysis program, HISCOAP, reads the SCOAP expression diagrams for the modules used in the circuit, and evaluates the SCOAP measure in a systematic manner. The program has been implemented on a Sun/SPARC workstation, and we present results on several benchmark circuits, both combinational and sequential. We show that our algorithm also has a straightforward parallel realization.

Abstract:

Test points choosing are the beginning of optimization of design for testability. With the consideration of uncertain influences on the tests of electronic equipment, the model for design for testability was proposed based on hybrid diagnosis modified by Bayesian network. Based on the new model, the algorithm of MBQPSO was proposed, which could take use of multi-dimension searching mechanism to choose test points according to uncertain correlation matrix between failure modes and tests. With the experiment, the result of this proposed method is closer to the reality and can provide better guidance for future design for testability.

Abstract:

By weighing reliability, maintainability, availability and life-cycle cost of equipment which are influenced by testability，the testability indexes of system level BIT are determined on the basis of maximum system reliability & maintainability and minimum the life-circle cost. The influence mathematical models of system reliability, maintainability, availability and life-circle cost are established. According to these mathematical models, the multi-objective optimization model of system-level BIT testability indexes is established. The multi-objective optimization model is solved using Non-dominated Sorting Genetic Algorithm II, and the validity of the multi-objective optimization model is proved through an example.

Abstract:

Generally, there exist random-pattern resistant faults that result in the poor fault coverage in Build-In Self-Testing (BIST) scheme. In this paper, we propose a method to enhance the random pattern testability by a circuit restructuring technique, called circuit rewiring. The basic idea of rewiring is to replace a wire by another wire with the circuit functionality remaining unchanged. For two types of rewiring, fanin rewiring and fanout rewiring, we first analyze the testability change for each type of wire replacement. Based on the analysis, an efficient algorithm is given to enhance circuit testability. For a poor observability node, we try to increase its observability by adding an additional fanout to the node and removing an alternative wire whose source node has relatively good observability. The technique does not introduce any hardware overhead and performance degradation since a wire addition is followed immediately by another wire removal. Thus, it is basically cost-free when compared to other testability enhancement techniques.

Abstract:

While the performance, density, and complexity of application-specific systems increase at a rapid pace, equivalent advances are not being made in making them more easily testable, diagnosable, and maintainable. Even though testability bus standards, like JTAG Boundary Scan, have been developed to help eliminate these costs, there exists a need for efficient hardware and software tools to support them. Hence, a testability design and hardware support environment for application-specific systems is described which provides a designer with a set of hardware modules and circuitry, that support these standards and software tools for automatic incorporation of testability hardware, as well as automatic test vector and test program generation.

Abstract:

The Multi-signal Flow Graph (MFG) is a simple and effective system modeling methodology, widely used in testability analysis and fault diagnosis field. In order to shorten the maintenance time and reduce the influence of human factors, the MFG method was introduced, and it was used to set up the testability model of aircraft Audio Management Unit (AMU) and found the fault-testability dependency matrix and the fault-fault dependency matrix. Based on dependency matrix and real unit fault message, the trapezoidal fuzzy number algorithm was introduced, thus the new fault diagnosis method was generated. Finally, an example proves that the fault diagnosis algorithm can not only locate the fault more accurately, but also improve the maintenance efficiency.
