Compositional Specification and Model Checking in GSTE

We propose a compositional specification and verification approach based on GSTE (Generalized Symbolic Trajectory Evaluation). There are two main contributions. First, we propose a specification language that allows concurrent properties be described succinctly in a compositional algebraic manner. Second, we show a precise model checking solution for a compositional specification through automata construction, but much more importantly and practically, we develop an efficient model checking algorithm for directly verifying the compositional specification. At the end, we show the result of our approach in the verification of a micro-instruction scheduler in a state-of-the-art microprocessor.
