Verification of design decisions in ForSyDe

The ForSyDe methodology has been developed for system level design. Starting with a formal specification model that captures the functionality of the system at a high abstraction level, it provides formal design transformation methods for a transparent refinement process of the specification model into an implementation model that is optimized for synthesis. A transformation may be semantic preserving or a design decision. The latter modifies the semantics of the system level description and changes the meaning of the model. The main contribution of this paper is the incorporation of model checking to verify that refined system blocks satisfy the design specification. We illustrate the translation of the ForSyDe code to the SMV language and the verification of local design decisions with a case study of a ForSyDe equalizer model.
