Option to optimize input paths for Switch and Multiport Switch blocks
Model Configuration Pane: Simulation Target
Description
This parameter specifies whether the software optimizes input paths forSwitch and Multiport Switch blocks. The software optimizes by executing only the blocks required to compute the control input and the data input selected by the control input. This optimization improves execution speed of simulation and generated code. It has these limitations:
- Blocks that determine the input values must:
- Have inherited (
-1) or constant (inf) sample time - Not have output signals designated as test points
- Not be multirate
- Not have states
- Have inherited (
- Model blocks are not supported.
- S-Function blocks are supported only when you enable the
SS_OPTION_CAN_BE_CALLED_CONDITIONALLYoption.
Settings
on (default) | off
on
The software optimizes the execution of blocks that determine the control and data inputs for Switch and Multiport Switch blocks.
off
The software executes blocks driving the Switch andMultiport Switch block input ports at each time step.
Recommended Settings
