SVM is a stand-alone simulator that does not depend on any other modeling and simulation tool. However, it can be seamlessly integrated with AToM. A plugin for AToM generates DCharts model descriptions from its graphical representation in AToM. The user may then save the descriptions in text files to be simulated by SVM. Alternatively, the generated model descriptions can also be stored in memory and be simulated by SVM immediately without being saved. In the latter case, SVM highlights the current states and enabled transitions in AToM during the simulation (Figure 6.4).
The SVM plugin adds a DCharts meta-model to AToM. It is developed on the basis of Spencer Borland's statecharts meta-model for AToM . Three buttons are available to simulate the model in the current canvas immediately, generate .des model description to a text file, and generate Java source code from the current model with SCC (discussed later). The designer is thus able to design the model in the AToM visual environment, and access to these functions simply by clicking on the corresponding buttons.
