Abstract Rapid advancements in Software Verification and Validation have been critical in the wide development of tools and techniques to identify potential Concurrent bugs and hence verify the software correctness. A concurrent program has multiple processes and

Software verification for programmable logic controllers
free download

Programmable logic controllers (PLCs) occupy a big share in automation control. Their programming languages are, however, born out of historical needs and do not comply to state-of-the art programming concepts. Moreover, programming is mostly undertaken by the

Exploiting structure for scalable software verification

Formal software verification is a software engineering technique for modeling a software systems source code, and then proving properties about it, such as freedom from security vulnerabilities. Though proofs are largely automated, formal source code modeling is time

Verification and validation of software components and component based software systems
free download

One premise with component based software technology is that the software component consumers, that is the software system builders, can decrease their effort needed for, among other things, verification of their component based software systems compared to traditional

Probabilistic techniques for software verification
free download

The various techniques for verification of proper software behaviour can be separated into probabilistic and deterministic ones. Deterministic techniques mainly qualify for small Programms with very high reliability requirements. The probabilistic ones qualify for large

Using range analysis for software verification
free download

Our main approach is based on generating a linear constraint system, which solution represents possible value ranges for program variables. The framework is an extension of the work by Radu Rugina and Martin Rinard described in Symbolic bounds analysis of

Teaching software verification and validation course: A case study
free download

Software verification and validation (V V) is one of the significant areas of software engineering for developing high quality software . It is also becoming part of the curriculum of a universities software and computer engineering departments. This paper reports theThis monograph is mainly based on the research that has been conducted in the Verification Laboratory at the University of California, Santa Barbara, in the last decade. String analysis has been an interesting and fruitful area to work on, leading to many research results some

Exploring the Software Verification and Validation Process with Focus on Efficient Fault Detection
free download

Quality is an aspect of high importance in software development projects. The software organizations have to ensure that the quality of their developed products is what the customers expect. Thus, the organizations have to verify that the product is functioning asThis Series addresses current and future challenges pertaining to embedded hardware, software , specifications and techniques. Titles in the Series cover a focused set of embedded topics relating to traditional computing devices as well as high-tech appliancesParameterisation. Many distributed systems should be correct whatever the value of some parameter. The problem is to validate the system for all possible values.(Strictly speaking, we deal here with an infinite family of systems, but the family can usually be seen as one

Using CSP for software verification
free download

In this paper, we present our approach to verifying software by synthesizing a CSP model from its compiler intermediate representation. This allows us to reason about the implementations of concurrent programs on the CSP level and to reuse existing CSP tools

Range analysis for software verification
free download

One of the main challenges of formal software verification is the ability to handle programs of realistic size. Model checking suffers from the state explosion problem which is even further exacerbated in the context of software verification . In this paper, we propose the use of

Software verification for Java 5

Purpose The enhanced for loop allows to iterate through a collection or an array without having to create an explicit Iterator or counter variable.

Efficient SAT-based Bounded Model Checking for Software Verification .
free download

This paper discusses our methodology for formal analysis and automatic verification of software programs. It is currently applicable to a large subset of the C programming language that includes bounded recursion. We consider reachability properties, in particular

Static Analysis tools, a practical approach for safety-critical software verification
free download

Static code analysis tools available today range from Lintbased syntax parsers to standards compliance checkers to tools using more formal methods for verification . As safety critical software complexity is increasing, these tools provide a mean to ensure code quality, safety

Agent-based distributed software verification

Despite decades of research, the takeup of formal methods for developing provably correct software in industry remains slow. One reason for this is the high cost of proof construction, an activity that, due to the complexity of the required proofs, is typically carried out using
