Utility methods to work with variant elements

Since R2023b

Description

The Simulink.VariantUtils class provides a set of utility methods to work with variant blocks in Simulink®. With these methods you can:

• Convert a Subsystem, Model, or Configurable Subsystem block to a Variant Subsystem block.
• Convert a Variant Subsystem block to a Variant Assembly Subsystem block.
• Display or change behavior of variant condition legend.
• Update ports in a Variant Subsystem block to match its variant choices.

Methods

Examples

collapse all

Convert the Subsystem block Controller in the f14 model to a Variant Subsystem block.

open_system('f14'); Simulink.VariantUtils.convertToVariantSubsystem('f14/Controller');

Convert the Subsystem block Controller in the f14 model to a Variant Subsystem block in expression mode with control expression as V==1, and the Variant activation time as update diagram and Built-in empty choice turned on.

open_system('f14'); Simulink.VariantUtils.convertToVariantSubsystem('f14/Controller', "VariantControlMode", ... 'expression', 'VariantControl', 'V==1', 'VariantActivationTime', 'update diagram', 'AllowZeroVariantControls', 'on', 'PassThrough', 'off');

Convert the Model block CounterA in the sldemo_mdlref_basic model to a Variant Subsystem block.

open_system('sldemo_mdlref_basic'); Simulink.VariantUtils.convertToVariantSubsystem('sldemo_mdlref_basic/CounterA');

You can convert a Configurable Subsystem block to a Variant Subsystem block using the convertToVariantSubsystem method. See Convert Configurable Subsystem to Variant Subsystem.

Version History

Introduced in R2023b

The convertToVariant,convertToVariantAssemblySubsystem, and variantLegend methods will be removed from the Simulink.VariantManager class in a future release. The method calls continue to work with a warning.

Use the Simulink.VariantUtils class to access these methods. TheconvertToVariant method in the Simulink.VariantManager class has been renamed to convertToVariantSubsystem in theSimulink.VariantUtils class.
