Abstract
Message Sequence Charts (MSC) is a graphical trace language for describing and specifying the communication behaviour of distributed systems by means of message interchange. (Timed) Maude is a formal object-oriented specification language which combines algebraic specification techniques for describing complex data structures with (timed) term rewriting to deal with dynamic behaviour. In this paper we show first how to formalize MSC in Timed Maude. Then we give a translation of timed rewriting to untimed rewrite systems and use this translation to execute Message Sequence Charts with the Elan system, a powerful tool which combines Rewriting Logic with a language of rewriting strategies. We illustrate our approach with the bench mark example of a railroad crossing.
