Abstract

We point out deficiencies of previous treatments of liveness. We define a new liveness condition in two forms: one based on finite trace theory and the other on automata. We prove the equivalence of these two forms. We introduce a safety condition and derive modular and hierarchical verification theorems for both safety and liveness. Finally, we give an algorithm for verifying liveness.
