As Enterprise Architect uses a dynamic, script driven Simulation mechanism that analyzes and works with UML constructs directly, there is no need to generate intermediary code or compile simulation 'executables' before running a Simulation. This results in a very rapid and dynamic Simulation environment in which changes can be made and tested quickly. It is even possible to update Simulation variables in real time using the Simulation Console window. This is useful for testing alternative branches and conditions 'on the fly', either at a set Simulation break point or when the Simulation reaches a point of stability (for example, when the Simulation is 'blocked').
- Dynamically execute your behavioral models
- Define and fire triggers into running Simulations
- Define and use sets of triggers to simulate different event sequences
- Auto-fire trigger sets to simulate complex event histories without user intervention
- Update Simulation variables 'on the fly' to change how Simulations proceed
- Create and call COM objects during a Simulation to extend the Simulation's reach and input/output possibilities
- Inspect Simulation variables at run time
- Set a script 'prologue' for defining variables, constants and functions prior to execution
- Use multiple Analyzer Scripts with differing 'prologues' for running the Simulation under a wide range of conditions
In the Unified and Ultimate Editions it is also possible to simulate BPMN models.
Using the Model Simulator, you can simulate the execution of conceptual model designs containing behavior. When you start a Simulation, the current model Package is analyzed and a dynamic Simulation process is triggered to execute the model.
To get up and running with Simulation, the only steps required are:
- Build a behavioral diagram (State or Activity for manual or dynamic execution, Sequence for manual interaction only)
- Optional: load the 'Simulation Workspace' layout - a fast way of bringing up all the frequently used Simulation windows
- Click on the Simulator
If the diagram contains any external elements (those not in the same Package as the diagram) you will have to create an Import connector from the diagram's Package to the Package containing the external elements. To do this, drag both Packages from the Browser window onto a diagram and then use the Quick Linker arrow to create the connector between them.
