RESUMO

A Graphic Editor of Statecharts is presented. Statecharts are an extension of conventional state diagrams where the concepts of hierarchy, concurrency and communication have been added. We present a particular graphic interface which supports the specification of reactive systems by means of the statechart notation. At the end of an editting session we offer a statechart simulation option. During a simulation the states, which the system is at, are highlighted and the state swappings due to event occurrences are performed. A textual description of an edited statechart may as well be generated. This description is liable to be converted into an executable program which behaves in a functionally equivalent manner. It is possible to execute this program at the same time the simulation of the original statechart is running. The program sends to the simulator the events identifiers, by means of the sockets mechanism, as soon as they occur. The simulator then applies the state swapping operation. With this kind of simulation it is possible to provide some support to debug programs at the statechart level
