Abstract
This paper presents a migration approach from a class of hierarchical B models to CSP. The B models follow a so-called polling pattern, suitable for reactive systems, and are automatically translated into a set of communicating CSP processes with the same behaviour. The structure of the CSP model matches that of the B model and may be formally analysed using model checking. Selected CSP processes may then be further refined and synthesised to hardware, while the remaining modules would be mapped to software using B refinements. The translation proposed here paves the way for a model-based approach to hardware and software co-design employing complementary formal methods.
