Abstract

Event-B is a state-based formal method for system development. The Event-B mathematical language does not support a syntax for the direct definition of structured types such as records. This paper proposes extending the Event-B language with direct record definitions.A key feature is the ability to extend records with new fields in refinement steps. The XEvent-B tool, which supports a textual representation of Event-B models, is extended to provide support for direct record definition and automatic transformation of record structures into standardEvent-B elements. We demonstrate this work by modelling of the Tokeneer case study.
