CASE (computer aided software engineering) tools based on the Specification and Description Language (SDL) are nowadays serving increasingly as the engineering platforms for rapid application development (RAD). This paper presents some general concepts for achieving the modelling and simulation of B-ISDN signalling protocols on such an SDL'92 engineering platform (SDL'92 toolset). The designed simulation model is completely specified in SDL'92. The corresponding discrete-event simulator is automatically generated from the SDL'92 specifications. Using the abstract data types (ADT) of SDL'92, the queuing models can be coded within SDL'92 specifications for performance modelling. To make the most of the SDL'92 engineering platform, a working paradigm for developing and verifying a discrete-event simulator is proposed.
