For R2022b and later:
As of R2022b, Simulation pacing is supported in Rapid Accelerator and Simulink Compiler. This setting can be used to run a model in Simulation pacing at a "soft real-time" pace.
For R2022a and earlier:
If you are using R2022a or earlier, Simulation Pacing is not supported in Rapid Accelerator or Simulink Compiler. You can achieve a similar effect by adding a "pause()" to the postStepFcn of the compiled app to slow the simulation. Attached is an example that shows the basics of this method and controls the pause time using a slider. The "Sim Pacing" display in the app displays the total wall clock time divided by the total simulation time.
This is a simple control scheme that requires manual tuning but you can adapt the example to have the app attempt to tune the pause time automatically to reach a desired simulation rate.
