Executive Summary

In this paper, the authors present a framework aimed at simulating control logics specified in the higher-order logic of the Prototype Verification System. The framework offers a library of predefined modules, a method for the composition of more complex modules, and an event-driven simulation engine. A developer simulates the specified system by providing its input waveforms as functions from time to logic levels. Once the simulation experiments give sufficient confidence in the correctness of the specification, the model can serve as a basis for the formal verification of desired properties of interest.
