A UNIFIED FRAMEWORK FOR PROGRAM VERIFICATION
一个统一的程序验证框架

This paper presents a simpler approach in which both a program and its properties are specified by formulas in the same logic: the temporal logic. A transition module of a program is defined and the notion of temporal run semantics, which is a temporal formula precisely characterizing the program is presented. Taken temporal logic as specification language, the correctness of a program means that the formula specifying the program implies the formula specifying the property, where implies is ordinary logical implication. Therefore this approach gives a unified framework for specifying and verifying concurrent programs and allows a full utilization of the existing comprehensive proof systems developed for proving temporal properties of systems. A simple example of a buffer system is presented to illustrate this method and show that the approach is very promising.
