In this paper we study coverage metrics for model checking from a practical point of view. Coverage metrics are based on modifications we apply to the system in orde

A layer is the set of BDD nodes labeled by a given variable, and its characteristic function is represented using BDDs. Meta-BDDs are implemented upon a standard BDD library and they support layered (decomp

Unfortunately, these algorithms may produce false negatives. Significant effort must then be spent for determining whether the failures are indeed real

In contrast to other abstraction refinement algorithms, we always work with abstract models whose sizes depend only on the length of the formula θ (but not on the size of the system, which might be infinite).
