Preserving Partial-Order Runs in Parametric Time Petri Nets

Abstract

Parameter synthesis for timed systems aims at deriving parameter valuations satisfying a given property. In this article, we target concurrent systems. We use partial-order semantics for parametric time Petri nets as a way to both cope with the well-known state-space explosion due to concurrency and significantly enhance the result of an existing synthesis algorithm. Given a reference parameter valuation, our approach synthesizes other valuations preserving the partial-order executions of the reference parameter valuation. We show the applicability of our approach using a tool applied to asynchronous circuits.
