Stateflow

Debug the Model During Simulation

The Stateflow Debugger supports functions like single stepping, animating, and running up to a designated breakpoint and then stopping.

These steps show how to step through the simulation using the Debugger:

1. Display the Debugger by choosing Debug from the Tools menu of the graphics editor.
2. Select the Breakpoints: Chart Entry check box to tell the Debugger you want it to stop simulation execution when the chart is entered.
3. Select Start to start the simulation.

1. Informational and error messages related to the S-function code generation for Stateflow blocks are displayed in the MATLAB Command Window. When the target is built, the graphics editor becomes read-only (frozen) and the Debugger window is updated and looks similar to this.

   

4. Select Step to proceed one step through the simulation. The Debugger window displays the following information:
• Where the simulation is stopped
• What is executing
• The current event
• The simulation time
• The current code coverage percentage

1. Watch the graphics editor window as you click the Step button to see each transition and state animated when it is executing. After both Power_off and Power_on have become active by stepping through the simulation, the code coverage indicates 100%.

5. Choose Stop from the graphics editor Simulation menu to stop a simulation. Once the simulation stops, the model becomes editable.
6. Select Close in the Debugger window.
7. Choose Close from the File menu in the Simulink model window.
