Abstract

This paper provides a denotational semantics to a subset of Timed RAISE Specification Language(RSL) using Extended Duration Calculus(EDC) model. We use some novel features of EDC which play the vital role in formalizing real-time programs and verification of real-time properties. Some characteristic algebraic laws of Timed RSL is presented, which can be proved from the denotational semantics, and be used in program transformation and optimization.
