On deriving equivalent architecture model from system specification

This paper presents a formal approach to correctly refine a system specification to an architecture model. The tasks in the system specification are distributed onto components of the system architecture to derive the architecture model. We present this refinement step and use formalisms to prove that the derived architecture model is equivalent to the specification. This approach aims at solving the verification problem in system level design through gradual refinements that produce an equivalent output model at each step.
