Tunable Parameters

There are some parameters, such as the Sine Wave block's Frequency parameter, that you can change or tune while a simulation runs. Many parameters cannot be changed while a simulation is running. This is usually the case for parameters that directly or indirectly alter a signal's dimensions or sample rate.

Note    Opening a dialog box for a source block causes the simulation to pause. While the simulation is paused, you can edit the parameter values. However, you must close the dialog box to have the changes take effect and allow the simulation to continue.

How to Tune Tunable Parameters

To tune a tunable parameter during a simulation, double-click the block to open its Block Parameters dialog, change any tunable parameters to the desired settings, and then click OK. The simulation continues to run, but with the new parameter settings.

Tunable Parameters During Simulation

Block parameters can be tunable in simulation, in the Simulink Performance Tools Accelerator, and in Real-Time Workshop external mode. When a parameter is marked "Tunable" in a reference page, it is tunable only in simulation, unless indicated otherwise.
