Abstract
We build on existing work in structured and formal methods integration by proposing a formal denotational semantic function between the syntax of Ward/Mellor SA/RT models and the syntax of the Synchronous Calculus of Communicating Systems (SCCS). In order that our semantic will encompass the whole of the Ward/Mellor essential model, we discuss how the mini-specifications and data dictionary which accompanies SA/RT dataflow diagrams, might be formalised using extensions to Bruns' Value-Passing CCS value expressions. We outline our own Value-Passing extensions to SCCS, and overview a semantic function, written in the Z specification language, from Ward/Mellor to Value-Passing SCCS. Finally, we document our conclusions.
