When simulating a model, you can display and manipulate simulation information in diagrams a similar way you do it in the Simulation window. For example, you can see and edit runtime values directly on Part shapes or send a trigger and see a flowing item with its name on a path.
In diagrams, the following simulation information can be displayed:
You can display and manipulate simulation information only in diagrams that are based on a Composite Structure Diagram. However, the flowing information on paths can be displayed both in diagrams based on a Composite Structure Diagram and an Activity Diagram.
This sample model simulation demonstrates how you can use diagrams to view and manipulate the same simulation information as in the Simulation window.
