The Time-Scaled Activity Diagram Simulator software simulates and animates time-tagged events as an overlay on activity and internal block diagrams in MagicDraw as a plugin application. “Events” are quite generic and include atomic actions, compound actions, signal and message exchanges, invocations, and more. Events are specified in a schedule in a text file, which is ingested by the plug-in application. Concurrent and synchronized execution specified in the event schedule is illustrated within and across diagrams. Events correspond to nodes and edges of hierarchical activity models and corresponding structural decomposition. This software can be used to visually communicate the execution and timeline of any collection of scheduled events, including business, software, and spacecraft processes and procedures, and is applicable to most if not all missions.

This software is deterministic where others, like Cameo Simulation Toolkit, are not and where constraining events to a specified, editable schedule is not possible.
