Unfolding Models of Asynchronous Systems: Applications to Analysis and Synthesis Victor Khomenko Newcastle University School of Computing victor.khomenko@ncl.ac.uk Abstract. Analysis and synthesis of concurrent systems suffers from combinatorial state space explosion. That is, even a relatively small sys- tem specification can (and often does) yield a very large state space. One of the prominent techniques for alleviating this problem is based on complete prefixes of Petri net unfoldings. It relies on the partial order view of concurrent computation, and represents system states implicitly, using an acyclic Petri net. This talk describes applications of the un- folding technique to analysis of concurrent systems in general, and to verification and synthesis of asynchronous circuits in particular.
