Automating checking of models built using a graphically based formal modeling language

摘要

RDT is a graphical formal modeling language in which the modeler works by constructing diagrams of the processes in their model which they join together to form complete systems. Aside from the benefits which accrue as a side effect of building a formal model of a proposed systems, these diagrammatic models can be useful as a means of communication between the development team and the users. However one of the greatest benefits of a formal model is that it can be subjected to rigorous examination to ensure that it satisfies properties required of the system. This paper describes the transformation used by the RDT toolset to generate Promela code (the input language of the SPIN model-checker) automatically from a model.
