Abstract

We present an approach to automatically generating invariants for timed automata models. The CIPM algorithm that we propose first computes new invariants for timed automata control locations taking their originally defined invariants as well as the constrains on clock variables imposed by incoming state transitions into account. In doing so the CIPM algorithm also prunes idle transitions, which are transitions that can never be taken, from the automaton. We discsuss a prototype implementation of the CIPM algorithm as well as some initial experimental results.

Keyphrases: invariant generation, program verification, real-time systems
