RT-Studio: A Tool for Modular Design and Analysis of Realtime Systems Using Interpreted Time Petri Nets

RT-Studio (Real Time Studio) is an integrated environment for modeling, simulation and automatic verification of realtime systems modeled as networks of Interpreted Time Petri Nets (ITPNs). The tool allows to construct several abstractions for ITPNs suitable to verify reachability, linear and branching properties, in addition to a TCTL model checker. In this paper we describe the ITPN model as a proposed extension to the classical TPN model and describe the modular modeling capabilities of RT-Studio. The classical railroad crossing model is used to illustrate these capabilities.
