The Circus specification language combines elements for complex data and behavior specifications, using an integration of Z and CSP with a refinement calculus. Its semantics is based on Hoare and He’s unifying theories of programming (UTP). Isabelle/Circus is a formalization of the UTP and the Circus lan-guage in Isabelle/HOL. It contains proof rules and tactic support that allows for proofs of refinement for Circus processes (involving both data and behavioral aspects). This environment supports a syntax for the semantic definitions which is close to textbook presentations of Circus. These theories are presented with details in [9]. This document i
