Abstract
The SPECS tool is a window-oriented, menu-driven net editor and an integrated simulator with animation support for high-level Petri nets, embedded in an object-oriented programming environment and extended with a hierarchical structuring facility. However, the use of the tool is not limited to Petri-net based specifications. It is possible to describe the basic modeling elements of other specification methods with Petri nets. The initial results of emulating the real-time structured analysis and structured design method on the SPECS environment are presented. The basic elements of the method are modeled as high-level Petri nets to meet the execution rules, known as the Ward transformation schema. The SPECS simulator is adapted to support the scheduling principle of those execution rules. The well-known cruise control system specification is presented in a form which allows its execution on the SPECS tool.<>
