CPAchecker with explicit-value analysis based on CEGAR and interpolation: (Competition contribution)

Abstract

CPAchecker is a freely available software-verification framework, built on the concepts of Configurable Program Analysis (CPA). Within CPAchecker, several such CPAs are available, e.g., a Predicate-CPA, building on the predicate domain, as well as an Explicit-CPA, in which an abstract state is represented as an explicit variable assignment. In the CPAchecker configuration we are submitting, the highly efficient Explicit-CPA, backed by interpolation-based counterexample-guided abstraction refinement, joins forces with an auxiliary Predicate-CPA in a setup utilizing dynamic precision adjustment. This combination constitutes a highly promising verification tool, and thus, we submit a configuration making use of this analysis approach. © 2013 Springer-Verlag.
