Known Limitations of
startup variant activation time
The following are currently not supported with
Blocks with continuous states when they receive the
Blocks with Simscape™ physical connection ports.
The variant condition expression can contain only "
||" and "
Simulink.Parameterwith custom storage classes having
macrotypes are not supported for ERT based code generation.
Variant conditions with mix of code compile and startup gets combined during variant activation during propagation. Variant condition propagation with mix of code compile (
#if) and startup (
if) is not supported. Whenever code compile and startup gets combined it results in update diagram error. For more information, see Considerations and Limitations for startup Variant Activation Time.
Multi-input variant source with ‘Output function call’ selected to merge function-call signals is not supported.
A Variant Subsystem block with
startupactivation time and more than one variant choice does not support function-call signals on its outports.
Variant Manager constraints are not validated when variant control variable values are changed as part of fast restart workflows for variant blocks with
startupactivation time. For information on constraints, see Define Constraints for Variant Configurations.
