Abstract

In a previous paper we presented a method which allows to compute abstractions for parameterized systems modeled in the decidable logic WS1S. These WS1S systems provide an intuitive way to describe parameterized systems of finite state processes. The abstractions can be used to establish properties of the parameterized network. To be able to prove liveness properties, an algorithm is used which enriches the abstract system with fairness constraints. We summarize this verification method and present its application by the verification of both safety and liveness properties of a non-trivial example of a cache coherence protocol, provided by Steve German.
