An approach to test optimization in switched-capacitor systems based on fault simulation at switch-level is presented in this paper. The advantage of fault simulation at this granularity level is that it facilitates test integration as early as possible in the design of these systems. Due to their mixed-signal nature, both catastrophic and parametric faults must indeed be considered for test op...

This paper reports an investigation of Iddq test coverage of randomly generated test vectors and Iddq fault coverage estimation based on a new testability measure. Experimental results show that Iddq random vectors are as efficient as deterministic vectors, and that the proposed testability measure is capable of accurately estimating fault coverage of Iddq test.

We propose a dependence-based representation for object-oriented programs, named Call-based Object-Oriented System Dependence Graph (COSDG). Apart from structural features, COSDG captures important object-oriented features such as class, inheritance, and polymorphism. Novel features of COSDG include details of method visibility in a derived class, and different types of method call edges to dis...

Software Model Checkers have shown outstanding performance improvements in recent times. Moreover, for specific use cases, formal verification techniques have shown to be highly effective, leading to a number of high-profile success stories. However, widespread adoption remains unlikely in the short term and one of the remaining obstacles in that direction is the vast number of instances which ...

Prioritization of test cases is generally done to reduce the cost of regression testing. We prioritize our test cases so that those which are more important, by some measure, are made to run earlier in the testing phase. There exists a large variety of prioritization techniques in the literature, we have basically used coverage-based prioritization techniques (i.e., prioritization in terms of t...

The project focuses on examining the advantages of random verification with real examples. Random verification has two necessary parts, hierarchical testbench and coverage metrics. The layered testbench allows a verifier to improve the coverage by only modifying the randomization constraints at the highest level of abstraction. Although it might take a verifier more time to build such hierarchi...

High levels of design integration and increasing number of analog blocks within a system necessitate automated system-level analog test generation and fault simulation tools. We outline a methodology and toolset for specification-based automated test generation and fault simulation for analog circuits. Test generation is targeted at providing the highest coverage for each specified parameter. T...

In this paper, we propose a software reliability model that considers not only error generation but also fault removal efficiency combined with testing coverage information based on a nonhomogeneous Poisson process (NHPP). During the past four decades, many software reliability growth models (SRGMs) based on NHPP have been proposed to estimate the software reliability measures, most of which ha...

reducing test suite size without compromising the suite’s effectiveness in performing regression testing. This article presents a hybrid technique using the variable-based method that combines both selection and prioritization. It considers source code changes and coverage information with respect to each test case. Variables are the vital source of changes in the program, and this method captu...

“Software test-coverage measures” quantify the degree of thoroughness of testing. Tools are now available that measure test-coverage in terms of blocks, branches, computation-uses, predicate-uses, etc. that are covered. This paper models the relations among testing time, coverage, and reliability. An LE (logarithmic-exponential) model is presented that relates testing effort to test coverage (b...
