Verification of Real-Time Control Software Using PVS

by M. Lawford and H. Wu

Abstract: This paper provides preliminary results from an investigation of the use of PVS for the specification and verification of the real-time behavior of control systems software. Preliminary definitions are developed for specifying real-time software requirements. The definitions are used to specify a subsystem of an industrial real-time control system and then PVS is used to detect several errors in a proposed implementation and the original specification. Finally we prove that a corrected version of the implementation satisfies the updated version of the specification.
