Frama-C, A Collaborative Framework for C Code Verification: Tutorial Synopsis

摘要

Frama-C is a source code analysis platform that aims at conducting verification of industrial-size C programs. It provides its users with a collection of plug-ins that perform static and dynamic analysis for safety- and security-critical software. Collaborative verification across cooperating plug-ins is enabled by their integration on top of a shared kernel, and their compliance to a common specification language, ACSL. This paper presents a three-hour tutorial on Frama-C in which we provide a comprehensive overview of its most important plug-ins: the abstract-interpretation based plug-in Value, the deductive verification tool WP, the runtime verification tool E-ACSL and the test generation tool PathCrawler. We also emphasize different possible collaborations between these plug-ins and a few others. The presentation is illustrated on concrete examples of C programs.
