We present a tool, called cascade, to check assertions in C programs as part of a multi-stage verification strategy. cascade takes as input a C program and a control file (the output of an earlier stage) that specifies one or more assertions to be checked together with (optionally) some restrictions on program behaviors. For each assertion, cascade produces either a concrete trace violating the assertion or a deduction (proof) that the assertion cannot be violated.

Verification of C Programs Using Automated Reasoning2007 •
This paper presents a formal approach to detect vulnerabilities in a C program using the B formal method. Vulnerabilities denote faults that may be introduced uninten-tionally into programs making them behave incorrectly. Such faults (or programing errors) may lead to unpredictable be-havior and even worse well-motivated attackers may exploit them later to cause real damage. Basically, the proposed approach consists in translating the vulnerable aspects of a C program into a B specification. On this B specification proof and model checking activities are performed in order to detect the presence or absence of vulnerabilities. Com-pared to the existing vulnerability detection techniques, a proof-based approach permits to eliminate false alarms and denial of service attacks.

Verification and refutation of C programs based on k-induction and invariant inference2020 •
DepthK is a source-to-source transformation tool that employs bounded model checking (BMC) to verify and falsify safety properties in single- and multi-threaded C programs, without manual annotation of loop invariants. Here, we describe and evaluate a proof-by-induction algorithm that combines k-induction with invariant inference to prove and refute safety properties. We apply two invariant generators to produce program invariants and feed these into a k-induction-based verification algorithm implemented in DepthK, which uses the efficient SMT-based context-bounded model checker (ESBMC) as sequential verification back-end. A set of C benchmarks from the International Competition on Software Verification (SV-COMP) and embedded-system applications extracted from the available literature are used to evaluate the effectiveness of the proposed approach. Experimental results show that k-induction with invariants can handle a wide variety of safety properties, in typical programs with loop...
