Debug Simulations in the Simulink Editor
Using debugging tools available in the Simulink® Editor, you can:
Set breakpoints to pause a simulation at a point of interest.
View and manage breakpoints throughout your model.
Step through a simulation one time step at a time or one block at a time.
Add port value labels to signals to see how signal values change as you step through the simulation.
The model canvas shows breakpoints and port value labels in context within the block diagram so you can analyze, debug, and modify your model in one place.
|View, configure, and manage breakpoints for debugging models (Since R2022a)
|Simulation Stepping Options
|Enable stepping back and configure number of time steps to move when stepping through simulation
|Simulation Pacing Options
|Slow simulation to a specified ratio of simulation time to wall clock time
Pause and Step in Simulation
- Step Through Simulation
Step through major time steps, view signal values in the block diagram, and configure simulation stepping options.
- Debug Simulation Using Signal Breakpoints
Set breakpoints to pause simulation then step through simulation block by block.
