A Semantic Embedding of the Ag Dynamic Logic in PVS


Carlos López Pombo, Sam Owre, and Natarajan Shankar


Ag is a specification language presented as a syntactic sugaring of the First-Order Dynamic Logic of Fork Algebras. This language is particularly attractive due to its expressive power, easy-to-understand semantics, and the existence of a complete deductive system. We will briefly present the language together with a complete deductive calculus and some theoretical results about its expressive power. We then show how the higher-order logic theorem prover PVS can be used to build a semantic framework for reasoning about specifications written in Ag by encoding the semantics within this powerful general-purpose tool. We then illustrate how this semantic embedding can be used by means of a case study of a cache system specification.
