Compositional Reactive Semantics of SystemC and Verification with RuleBase

We present a behavioral semantics of SystemC that succinctly captures its reactive features, clock and time references, macroand micro-time model, and allows the specification of a network of synchronous and asynchronous components communicating through either high-level transactions or low-level signal and event communications. The proposed semantic framework demonstrates the anomalies introduced by the simulation kernel, in spite of the macroand micro-time scales. The framework further relates the simulation and logical correctness and provides a technique for scaling up the verification while keeping the correctness intact. Furthermore, we translate SystemC components to RuleBase using our semantic characterization that permits testing and verification of heterogenous designs. We illustrate the verification of a Central Locking System (CLS) designed in SystemC.
