Evaluating, Testing, and Animating PVS Specications

Abstract

We explore ways to enhance the utility of PVS for evaluating, testing, and animating PVS specifications. The PVS ground evaluator is the focus of the work. We describe a mechanism to provide semantic attachments for PVS symbols while preserving soundness, and discuss strategies to provide a generic framework for integrating independently developed applications with PVS. We explore these capabilities in the current system, but conclude that more effective functionality requires extensions to PVS. Recommendations for these extensions are outlined.
