A Less Elementary Tutorial for the PVS Specication and Verication System

PVS is averication systemthatprovides aspecication languageintegrated with support tools and a theorem-prover. It has been used at SRI and elsewhere to perform verications of several signicant algorithms primarily for fault-tolerance and large hardware designs. Using the more powerful strategies of PVS to automate easy proofs and the easypartsofhardproofs freesusers toconcentrateontruly dicult proofs. Automation also makes proofs more robust to changes in the specication, thereby facilitating active design exploration and adaptation to changed requirements. [via]
