Hybrid cegar: combining variable hiding and predicate abstraction
2007
Computer-Aided Design (ICCAD), IEEE International Conference on
Variable hiding and predicate abstraction are two popular abstraction methods to obtain simplified models for model checking. Although both methods have been used successfully in practice, no attempt has been made to combine them in counterexample guided abstraction refinement (CEGAR). In this paper, we propose a hybrid abstraction method that allows both visible variables and predicates to take advantages of their relative strengths. We use refinement based on weakest preconditions to add new
