More effective interpolations in software model checking

Abstract:

An approach to CEGAR-based model checking which has proved to be successful on large models employs Craig interpolation to efficiently construct parsimonious abstractions. Following this design, we introduce new applications, universal safety interpolant and existential error interpolant, of Craig interpolation that can systematically reduce the program state space to be explored for safety verification. Whenever the universal safety interpolant is implied by the current path, all paths emana...
