Using Simulink

Using the Simulink Accelerator with the Simulink Debugger

If you have large and complex models that you need to debug, the Simulink Accelerator can shorten the length of your debugging sessions. For example, if you need to set a time break that is very large, you can use the Accelerator to reach the breakpoint more quickly.

To run the Simulink debugger while in Accelerator mode:

1. Select Accelerator from the Simulation menu, then enter

• sldebug modelname
  

• at the MATLAB prompt.

2. At the debugger prompt, set a time break:

• tbreak 10000
  continue
  

3. Once you reach the breakpoint, use the debugger command emode (execution mode) to toggle between Accelerator and Normal mode.

Note that you must switch to Normal mode to step the simulation by blocks. You must also switch to Normal mode to use the following debug commands:

• trace
• break
• zcbreak
• nanbreak
• minor

For more information on the Simulink debugger, see Simulink Debugger.
