A simulation scope can combine any number of Statecharts and Activity-charts or portions of these. A portion a chart is a box (Activity and State) with its descendents. The simulation scope may include:
This scope is used when analyzing a component of the system or when the behavior of the entire system is described by a single Statechart. The single Statechart need not be connected to a control activity. This scope illustrates the interaction between components that are described by the different Statecharts. This technique is also useful when a Statechart represents the system and another represents the external environment. This scope is useful when the specification is incomplete but you want to analyze the completed portion. For example, simulate one orthogonal component of a vast Statechart. This scope is used to analyze the interaction of various parts of the system each described in a different Statechart or mini-spec corresponding to the control activities.
