Abstract

CSP-OZ is an integrated formal method which combines the state-oriented method Object-Z with the process algebra CSP, thereby allowing a description of static as well as dynamic aspects of a system. Checking correctness of CSP-OZ specifications can be done via a translation into (FDR-)CSP, on which automatic verification can be performed with the tool FDR if the resulting CSP process is not too large to be processed. This paper investigates how data abstraction techniques can be used to bring a translated specification within range of automatic verification.
