Combining partial orders and symbolic traversal for efficient verification of asynchronous circuits
Aleksei L Semenov, Alex Yakovlev · 2002
We propose an algorithm combining two approaches to PN verification: PN unfolding and BDD-based traversal. We introduce a new application of the PN unfolding method. The results of unfolding construction are used for obtaining the close-to-optimal ordering of BDD variables. The effect of this combination is demonstrated on a set of benchmarks. The overall framework has been used for the verification of circuits in an asynchronous microprocessor.
