Computing timed transition relations for sequential cycle-based simulation
Gianpiero Cabodi, Paolo Enrico Camurati, C. Passerone, Stefano Quer · 2003
In this paper we address the problem of computing silent paths in an Finite State Machine (FSM). These paths are characterized by no observable activity under constant inputs, and can be used for a variety of applications, from verification, to synthesis, to simulation. First, we describe a new approach to compute the Timed Transition Relation of an FSM. Then, we concentrate on applying the methodology to simulation of reactive behaviours. In this field, we automatically extract a BDD-based behavioral model from the RT or gate level description. The behavioral model as able to "jump" in time and to avoid the simulation of internal events. Finally, we discuss a set of promising experimental results in a simulation environment under the Ptolemy simulator.
