SimEvents Debugger

Debug SimEvents models

• 

Libraries:
SimEvents

Description

The SimEvents Debugger block enables the debugger for your SimEvents^® model. Using this block, you can:

• Inspect entities and their attribute values in storage blocks

• Set breakpoints on blocks and events

• Watch entities

Note

The SimEvents debugger is a preliminary version.

To start debugging your model:

1. From the SimEvents Library, add the SimEvents Debugger block into your SimEvents model.

2. In the Simulink^® Editor, click the Step Forward button.

   The debugger interface appears.

   

• Click the Continue simulation button () to begin the simulation in the debugger. When the simulation completes, the debugger interface closes.

• To explore their data and behavior, the model tree displays in the left pane. Select the elements in the tree.

• When done, on the Simulink editor, click the Stop button to stop the simulation.

Inspect Entities

To inspect entities in the debugger:

• To step to the next time step and inspect entities, in the Simulink editor, click the Step Forward button again. This action skips over all events at tnow.

• To step to the next event and inspect entities, in the debugger, click .

• To set a breakpoint:

  • At a particular time, use the Simulation Stepper to set breakpoints.

  • At an event on the event calendar, in the debugger, in the left pane, click an event calendar.

  • At every event, in the debugger, in the left pane, select the event calendar. In the Event Calendar Events pane, select the Break before event execution check box.

  • When an entity enters a block, in the debugger, select the block. At the bottom of the Inspector pane, select the Break upon entry check box.

  • When an entity leaves a block, in the debugger, select the block. At the bottom of the Inspector pane, select the Break prior to entity exit check box.

• To go to a breakpoint, in the debugger, click the Continue button ().

  Note

  When you stop the debugger at a breakpoint, the Simulink editor and the MATLAB^® Command Window appear unresponsive. However, you can inspect entities, set new breakpoints, and continue the simulation from the debugger window.

• To watch entities, in the left tree, click the block. In the Inspector pane, select the check box of the entity you want to watch.
