Safety critical systems must be formally verified to prove their correctness in order to avoid the loss of human life or a huge investment. Simulink is widely used in the industry to model safety-critical systems. NuSMV is the model checker which can be ...

Program equivalence [1] is the problem of proving that two programs are equal under some definition of equivalence, e.g., input-output equivalence. The field draws researchers from formal verification, semantics and logics. Program equivalence is ...

In the case of safety-critical applications, software testing plays an important role, as such applications failure results in huge financial losses or even human fatality. Hence, a systematic certification process, DO-178B that ensures safe software ...

Symbolic execution is a popular software testing technique that can help developers identify complex bugs in real-world applications. Unfortunately, symbolic execution may struggle at analyzing programs containing memory-intensive operations, such as ...

An Intermediate Representation (IR) is a data structure to represent a program. It represents each program entity as an object (IR object), having a unique identification number (ID). Static program analysis tools perform analysis on IRs of the input ...

In model-based fault diagnosis, it is assumed that a correct model of each program being diagnosed is available. That is, these models serve as the oracles of the corresponding programs. Differences between the behaviors of a model and the actual ...

Worst Case Execution Time (WCET) Analysis of real-time embedded applications is a critical task and needs to be performed on multithreaded programs, as there is a growing trend towards concurrent programming on multicore systems. This demands that ...

Automated software fault localization techniques aid developers in program debugging by identifying the probable locations of faults in a program with minimum human intervention. As software is growing in complexity and scale today, increasing the ...

Automated test generation has been proposed to allow test cases to be created with less effort. While much progress has been made, it remains a challenge to automatically generate strong as well as small test suites that are also relevant to engineers. ...
