Abstract: We present a state space method for Petri nets having a time concept based on a global clock and associating time stamps to tokens. The method is based on equivalence on states and makes it possible to condense the usually infinite state space of such timed Petri nets into a finite state space without loosing analysis power. The practical application of the method is demonstrated on a large example of an audio/video protocol by means of a computer tool implementing the method.
