The Design and Implementation of the Model Checking Algorithm for Real-time System Based on Timed Automata

This paper first gives a brief introduction of timed automata,clock region,region equivalence and clock zone. According to the region equivalence,the infinite state space of the timed automata can be transferred to the finite. Then through a typical example it describes the model checking technique for real-time system.We uses Visual C++ to implement the data structures and algorithms in the model checking of real-time properties. The correctness of these algorithms are proved by experience.
