Variant Event-Based Components

Execute initialize, reset, and terminate events and Simulink functions conditionally

You can activate or deactivate the execution of subsystems on a model initialize, reset, and terminate events depending on the variant control you select. You can also execute Simulink^® functions conditionally.

The code that you generate for event-based variant blocks can contain all the variant choices of a system. You can switch between the choices prior to code compile. For information on generating code with event-based variant blocks, see Variant Systems (Simulink Coder).

Blocks

Initialize Function	Execute subsystem on model initialize event
Reset Function	Execute subsystem on model reset event
Terminate Function	Execute subsystem on model terminate event
Simulink Function	Define a function using Simulink blocks

Classes

`Simulink.VariantControl`	Create a variant control variable object (Since R2021a)
`Simulink.Parameter`	Store, share, and configure parameter values
`Simulink.Variant`	Specify conditions that control variant selection

Functions

enumeration Class enumeration members and names

Objects

struct Structure array

Topics

Conditionally Execute Custom Initialize, Reinitialize, Reset, and Terminate Routines
The custom routine blocks(Initialize Function, Reinitialize Function, Reset Function, and Terminate Function) blocks are preconfigured subsystem blocks that enable you to add custom routines to the default initialize, reset, and terminate routines to change or read block states.
Conditionally Execute Simulink Functions
With variant blocks, you can conditionalize functions defined using Simulink Function blocks.
