SEB-cg: Code generation tool with algorithmic refinement support for event-b

Abstract

The guarded atomic action model of Event-B allows it to be applied to a range of systems including sequential, concurrent and distributed systems. However, the lack of explicit sequential structures in Event-B makes the task of sequential code generation difficult. Scheduled Event-B (SEB) is an extension of Event-B that augments models with control structures, supporting incremental introduction of control structures in refinement steps. SEB-CG is a tool for automatic code generation from SEB to executable code in a target language. The tool provides facilities for derivation of algorithmic structure of programs through refinement. The flexible and configurable design of the tool allows it to target various programming languages. The tool benefits from xText technology for a user-friendly text editor together with the proving facilities of Rodin platform for formal analysis of the algorithmic structure.
