CPN-AMI
CPN-AMI is a computer-aided software engineering environment based on Petri Net specifications. It allows the ability to specify the behavior of a distributed system and then to evaluate properties such as invariants (preservation of resources), absence of deadlocks, liveness or temporal logic properties (relations between events in the system) on it.
CPN-AMI relies on AMI-Nets, that are Well Formed Petri Nets with syntactic facilities. Well Formed Petri Nets were jointly elaborated between the University of Paris 6 (Université P. & M. Curie) and the University of Torino in the early 1990s. This Petri Net class is of interest since it enables the use of symbolic techniques for model checking and thus allow a very compressed way to store all the states of a system.
