A common semantic framework for the representation of the source code and the generated target code.
A formalization of the notion of “correct implementation” as a refinement relation.
A syntactic simulation-based proof method which allows to automatically verify that one model of the semantic framework, representing the produced target code, correctly implements another model which represents the source.
These, and other ingredients are elaborated in this paper, in which we illustrate the new approach in a most challenging case. We consider a translation (compilation) from the synchronous multi-clock data-flow language Signal to asynchronous (sequential) C-code.
