Abstract

This article discusses a new approach to model checking of real-time systems. One of the novel aspects of our approach is the fact that an unconventional approach is chosen to deal with representing symbolic state spaces. Its key feature is that it does not use a canonical representation for representing symbolic nodes, but an alternative representation based on splitting trees. We describe this approach in terms of the verification problem of parametric reacheability of systems described in an extension of timed automata. Additionally, we describe how we extended this approach to deal With more complex verification problems, namely the parametric verification of an extension of the real-time temporal logic TCTL. This resulted in a model checking tool called PMC. The practical application of our approach is addressed through the analysis and verification of the root contention protocol of the IEEE1394 (FireWire) standard using this tool.
