VALKYRIE: a validation subsystem of a version server for computer-aided design data

Abstract

Design methodologies specify the sequence in which verification programs must be successfully executed to determine a design's correctness. We present a mechanism for assisting designers in adhering to their methodology, specified as Prolog rules that must match a verification event log. A new version cannot be released if a methodology violation is detected. Designers can query for the source of their violation. The system has been implemented within a prototype Version Server.
