Modeling Timed Automata Theory in PVS

A mechanized system called FVofTA (Formal Verification of Timed Automata) for specifying and reasoning about real-time systems using TA (Timed Automata) theory in PVS (Prototype Verification System) is proposed in this paper. This system includes two parts: one for modeling real-time system using TA template in PVS and the other for proof intending for formal verification of real-times system. The first part of this system is given via a case study in this paper. The formal verification results for this case study show that our modeling method is effective. The method used in this system reflects the nature of the theory TA modeling and is easily grasped by the general user.
