Verifying a Time-Triggered Protocol in a Multi-language Environment

The multi-language environment Synchronie supports the design and formal veriication of synchronous reactive systems. Presently, Synchronie integrates three synchronous languages, Esterel, Lustre, and Argos. In the synchronous approach, not only the system but also its properties can be speciied using a synchronous language. In Syn-chronie properties can be formalised textually as Esterel or Lustre programs, or graphically as Argos programs. Moreover, properties may also be speciied as temporal logic formulas with past or future operators. It is shown how to specify and automatically prove properties of a time-triggered protocol taking advantage of this environment.
