ABSTRACT

Hoare triples (precondition, program, postcondition) have been incorporated in the verification system PVS (Prototype Verification System). Two approaches are presented: the conventional one, with a clear distinction between syntax and semantics, and another where programs are identified with their semantics. In the last approach specifications are embedded in the semantic framework, leading to a formalism where specifications and programming constructs can be mixed freely. This framework forms the basis of a formal method for the design of distributed real-time systems.
