Conditional input branch execution

Description

Improve model execution when the model contains Switch and Multiport Switch blocks.

Category: Simulation Target

Settings

Default: On

On

Executes only the blocks required to compute the control input and the data input selected by the control input. This optimization speeds execution of code generated from the model. Limits to Switch block optimization:

  • Only blocks with -1 (inherited) or inf (Constant) sample time can participate.

  • Blocks with outputs flagged as test points cannot participate.

  • No multirate block can participate.

  • Blocks with states cannot participate.

  • Only S-functions with option SS_OPTION_CAN_BE_CALLED_CONDITIONALLY set can participate.

Off

Executes all blocks driving the Switch block input ports at each time step.
