Integrating real-time into Spin: a prototype implementation

We present a discrete-time extension of Promela, a high level modelling language for the specification concurrent systems, and the associated Spin model checker. Our implementation is fully compatible with Spin's partial order reduction algorithm, which is indeed one of its main strengths. The real time package is for most part orthogonal to the other features of the tool, resulting in a modular extension. We have evaluated it by several experiments, with encouraging results
