Abstract: In some phases of system development state-based methods are adequate; in others event-based methods are adequate. Petri nets provide a system model which supports both methods and thus allow a smooth transition between the different phases of system development. Most temporal logics for Petri nets, however, do not support both methods.
In this paper we introduce a temporal logic for Petri nets which allows to argue on states as well as on events. This way, specifications in the early phases can be event based and verification in later phases can be state-based within a single formalism.
