Abstract

We present an approach to the top-down construction of process terms from trace specifications. Process terms are built from operators of CCS, CSP and COSY, and denote labelled Petri nets. Trace specifications are first order formulas of Zwiers' trace logic and denote sets of finite communication sequences. The link between process terms and trace specifications is given by a new notion of process correctness which deals with both safety and liveness properties. The top-down construction proceeds by an application of compositional transformation rules which refine the given trace specification stepwise into a process term satisfying the safety and liveness requirements of the specification.
