Abstract

Resolution-based proof analysis techniques have been proposed recently to identify a sufficient set of reasons for unsatisfiability derived by a CNF-based SAT solver. We have adapted these techniques to work with a hybrid SAT solver. We use the proof analysis technique with SAT-based BMC, in order to generate useful abstract models. Our abstraction procedure is used iteratively in a top-down framework, starting from the concrete design, where we apply BMC on increasingly more abstract models. We apply various SAT-based and BDD-based verification methods on these abstract models, in order to obtain proofs of correctness, or to perform deeper searches for counterexamples. We demonstrate the effectiveness of our prototype implementation on several large industry designs.
