Abstract:

This paper proposes a novel approach to modeling and verifying real-time systems for high reliability. To do so, we first extend projection temporal logic to timed projection temporal logic. Further, we define a timed modeling, simulation, and verification language (TMSVL) for real-time systems. As a result, both systems and desired properties can be expressed in TMSVL. In particular, real-time behaviors such as delay, timeout, and interrupt can be formalized. Compared with commonly used property specification language, TMSVL is capable of specifying more sophisticated properties such as quantitative timing properties, interval-related properties, and periodically repeated properties. Moreover, the unified model checking approach to verifying real-time systems via dynamical program execution is implemented. In addition, a case study for modeling and verifying a μC/OS-III multitask system with interrupt is conducted to demonstrate how the proposed approach works.
