Speed Up Variant Component Simulation

Improve simulation speed with fast restart, accelerator, and rapid accelerator modes

Use fast restart to perform iterative simulations on Simulink^® models containing variants without compiling the model or terminating the simulation each time you make changes to the model. You can change values for root inports, for model initial states, and from Workspace block data; tune parameters and root inputs; and simulate the model again without spending time on recompiling. For more information on fast restart mode, How Fast Restart Improves Iterative Simulations.

To speed up simulation of models where runtime is long compared to the time associated with compilation and checking to see if the target is up to date, use accelerator and rapid accelerator modes. For more information on accelerator modes, see How Acceleration Modes Work.

To speed up simulation, set the variant activation time of variant blocks to startup.

Featured Examples

Run Iterative Simulations Without Recompiling Model for Variant Systems Using Fast Restart

Run iterative simulations on a fog lamp controller system using fast restart. The fog lamp controller system can operate in Driver Switch mode or in Sensor Connected mode. In Driver Switch mode, the driver controls the intensity of the fog lamps. In Sensor Connected mode, a sensor adjusts the intensity of the fog lamps based on the intensity of ambient light in the external environment.
