CPAchecker with sequential combination of explicit-value analyses and predicate analyses (Competition contribution)

Abstract

CPAchecker is a framework for software verification, built on the foundations of Configurable Program Analysis (CPA). For the SV-COMP'14, we file a CPAchecker configuration that runs up to five analyses in sequence. The first two analyses of our approach utilize the explicit-value domain for modeling the state space, while the remaining analyses are based on predicate abstraction. In addition to that, a bit-precise counterexample checker comes into action whenever an analysis finds a counterexample. The combination of conceptually different analyses is key to the success of our verification approach, as the diversity of verification tasks is taken into account. © 2014 Springer-Verlag.
