Debugging

Analyze chart simulation for design inconsistencies

Set breakpoints to stop execution in specific objects, such as charts, states, transitions, graphical functions, truth table functions, local events, and input events. Enable, disable, and set conditions on breakpoints in the Breakpoints and Watch window. Add data that you want to monitor during simulation in the Breakpoints and Watch window. After execution stops at a breakpoint, change data values and step through the simulation.

In addition, during simulation, you can display and change the values of Stateflow^® data in the MATLAB^® Command Window.

For information on debugging Stateflow chart objects that you execute in MATLAB, see Debug a Standalone Stateflow Chart.
