Set or clear breakpoint to pause when state limits step size in simulation debugging session



xbreak sets or clears a breakpoint that pauses simulation when the value of a state in the model limits the step size in a simulation debugging session that uses a variable-step solver.

  • If the breakpoint was not set, the command sets the breakpoint.

  • If the breakpoint had been set, the command clears the breakpoint.

The step-size limiting state breakpoint can help debug and analyze models that require more steps than expected in a variable-step simulation.


This function is supported only for simulation debugging sessions started programmatically using the sldebug function or using the sim function with the 'debug' name-value argument.
