Predicate abstraction is a major method for verification of software. However, the generation of the abstract Boolean program from the set of predicates and the original program suffers from an exponential number of theorem prover calls as well as from soundness issues. This paper presents a novel technique that uses an efficient SAT solver for generating the abstract transition relation of ANSI-C programs. The SATbased approach computes a more precise and safe abstraction compared to existing predicate abstraction techniques.
