Active elements on a diagram will be annotated during simulation using the same annotation mechanism used in the active validation:
Active and visited elements will be annotated with red and green respectively.
Runtime values will be visible in the tooltip text of annotated elements.
Values flown through pins of action will be visible in the tooltip of annotated actions.
Duration of called activities will be visible in the tooltip of annotated call behavior actions if you simulate the activity with a specific duration mode.
If you select true as the value of the silent tag in the simulation configurations, Cameo Simulation Toolkit will not animate simulation and will simulate models in silent mode (see Simulation configuration and UI modeling for more information).
