The Simulink debugger allows you to run a simulation one method at a time, and examine the results of executing each method. As the model simulates, you can display information on block states, block inputs and outputs, and block method execution within the Simulink Editor. This allows you to pinpoint problems in your model to specific blocks, parameters, or interconnections.
Use the Simulink debugger to:
Monitor single block dynamics (for example, output and update) during a single major time step.
Look at state of system while executing a major time step.
Observe solver dynamics during a single major step.
Simulink Debugger must be active (started) for all the debugger commands to run.
Simulink also supports debugging with the Simulation Stepper, which lets you step back and forth through your simulation, viewing data and inspecting how and when the system changes states. For information, see How Simulation Stepper Helps With Model Analysis.
