Abstract: This paper presents reachability tree logic (RTL) and its integration with time Petri nets to specify and verify temporal behavior of high-assurance systems. In addition, the paper demonstrates how to reduce the complexity of model checking algorithm by using the reachability tree. A specification and verification toolkit, called NCUPN (National Central University Petri Net toolkit), has been implemented using Java. NCUPN is available on the Internet at

Keywords: NCUPT toolkit, Petri nets, RTL, formal methods, high-assurance systems, temporal logic.
