Interfacing software libraries from non-deterministic prototypes

Modeling software systems is one of the most obvious uses of a formal specification language. A software prototype, automatically generated from the specification, enables the developer to validate the system in real environment. However, real software systems are seldom developed from scratch, but rather built using existing libraries. In this paper we show how a program based on existing software libraries is modeled in the CO-OPN specification language and how a prototype code is generated from the specification. In particular, we study the interface between nondeterminist synchronous prototypes and deterministic asynchronous software libraries.
