Abstract

In [1] Bounded Model Checking with the aid of satisfiability solving (SAT) was introduced as an alternative to symbolic model checking with BDDs. In this paper we show how bounded model checking can take advantage of specialized optimizations. We present a bounded version of the cone of influence reduction. We have successfully applied this idea in checking safety properties of a PowerPC microprocessor at Motorola's Somerset PowerPC design center. Based on that experience, we propose a verification methodology that we feel can bring model checking into the mainstream of industrial chip design.
