Download or read book Survey of Existing Tools for Formal Verification written by . This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: Formal methods have come into wide use because of their effectiveness in verifying "safety and security" requirements of digital systems; a set of requirements for which testing is mostly ineffective. Formal methods are routinely used in the design and verification of high-consequence digital systems in industry. This report outlines our work in assessing the capabilities of commercial and open source formal tools and the ways in which they can be leveraged in digital design workflows.

Book Synopsis Scalable Techniques for Formal Verification by : Sandip Ray
Download or read book Scalable Techniques for Formal Verification written by Sandip Ray. This book was released on 2010-08-12. Available in PDF, EPUB and Kindle. Book excerpt: This book is about formal veri?cation, that is, the use of mathematical reasoning to ensure correct execution of computing systems. With the increasing use of c- puting systems in safety-critical and security-critical applications, it is becoming increasingly important for our well-being to ensure that those systems execute c- rectly. Over the last decade, formal veri?cation has made signi?cant headway in the analysis of industrial systems, particularly in the realm of veri?cation of hardware. A key advantage of formal veri?cation is that it provides a mathematical guarantee of their correctness (up to the accuracy of formal models and correctness of r- soning tools). In the process, the analysis can expose subtle design errors. Formal veri?cation is particularly effective in ?nding corner-case bugs that are dif?cult to detect through traditional simulation and testing. Nevertheless, and in spite of its promise, the application of formal veri?cation has so far been limited in an ind- trial design validation tool ?ow. The dif?culties in its large-scale adoption include the following (1) deductive veri?cation using theorem provers often involves - cessive and prohibitive manual effort and (2) automated decision procedures (e. g. , model checking) can quickly hit the bounds of available time and memory. This book presents recent advances in formal veri?cation techniques and d- cusses the applicability of the techniques in ensuring the reliability of large-scale systems. We deal with the veri?cation of a range of computing systems, from - quential programsto concurrentprotocolsand pipelined machines.

Book Synopsis A Formal Approach to Contract Verification for High-integrity Applications by : Zhi Zhang
Download or read book A Formal Approach to Contract Verification for High-integrity Applications written by Zhi Zhang. This book was released on 2016. Available in PDF, EPUB and Kindle. Book excerpt: High-integrity applications are safety- and security-critical applications developed for a variety of critical tasks. The correctness of these applications must be thoroughly tested or formally verified to ensure their reliability and robustness. The major properties to be verified for the correctness of applications include: (1) functional properties, capturing the expected behaviors of a software, (2) dataflow property, tracking data dependency and preventing secret data from leaking to the public, and (3) robustness property, the ability of a program to deal with errors during execution. This dissertation presents and explores formal verification and proof technique, a promising technique using rigorous mathematical methods, to verify critical applications from the above three aspects. Our research is carried out in the context of SPARK, a programming language designed for development of safety- and security-critical applications. First, we have formalized in the Coq proof assistant the dynamic semantics for a significant subset of the SPARK 2014 language, which includes run-time checks as an integral part of the language, as any formal methods for program specification and verification depend on the unambiguous semantics of the language. Second, we have formally defined and proved the correctness of run-time checks generation and optimization based on SPARK reference semantics, and have built the certifying tools within the mechanized proof infrastructure to certify the run-time checks inserted by the GNAT compiler frontend to guarantee the absence of run-time errors. Third, we have proposed a language-based information security policy framework and the associated enforcement algorithm, which is proved to be sound with respect to the formalized program semantics. We have shown how the policy framework can be integrated into SPARK 2014 for more advanced information security analysis.

Book Synopsis Formal Methods for Industrial Critical Systems by : Stefania Gnesi
Download or read book Formal Methods for Industrial Critical Systems written by Stefania Gnesi. This book was released on 2012-11-27. Available in PDF, EPUB and Kindle. Book excerpt: Today, formal methods are widely recognized as an essential step in the design process of industrial safety-critical systems. In its more general definition, the term formal methods encompasses all notations having a precise mathematical semantics, together with their associated analysis methods, that allow description and reasoning about the behavior of a system in a formal manner. Growing out of more than a decade of award-winning collaborative work within the European Research Consortium for Informatics and Mathematics, Formal Methods for Industrial Critical Systems: A Survey of Applications presents a number of mainstream formal methods currently used for designing industrial critical systems, with a focus on model checking. The purpose of the book is threefold: to reduce the effort required to learn formal methods, which has been a major drawback for their industrial dissemination; to help designers to adopt the formal methods which are most appropriate for their systems; and to offer a panel of state-of-the-art techniques and tools for analyzing critical systems.
