Examples
Make Variant Component
Create a top-level architecture model.
modelName = "archModel"; arch = systemcomposer.createModel(modelName); systemcomposer.openModel(modelName); rootArch = get(arch,"Architecture");
Create a new component.
newComponent = addComponent(rootArch,"Component");
Add ports to the component.
inPort = addPort(newComponent.Architecture,"testSig","in"); outPort = addPort(newComponent.Architecture,"testSig","out");
Make the component into a variant component.
[variantComp,choices] = makeVariant(newComponent)

Make Variant Component in Expression Mode
Create a top-level architecture model.
modelName = "archModel"; arch = systemcomposer.createModel(modelName); systemcomposer.openModel(modelName); rootArch = get(arch,"Architecture");

Input Arguments
component
— Component
component object
Component to be converted to variant choice component, specified as a systemcomposer.arch.Component
object.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: [variantComp,choices] =
makeVariant(newComponent,Name="NewVariantComponent",Label="NewVariantChoice",Choices=["NewVariantChoiceA","NewVariantChoiceB","NewVariantChoiceC"],ChoiceLabels=["Choice
A","Choice B","Choice C"])
Name
— Name of variant component
character vector | string
Name of variant component, specified as a character vector or string.
Example: [variantComp,choices] =
makeVariant(newComponent,Name="NewVariantComponent")
Data Types: char
| string
Label
— Label of variant choice
character vector | string
Label of variant choice from converted component, specified as a character vector or string.
Example: [variantComp,choices] =
makeVariant(newComponent,Name="NewVariantComponent",Label="NewVariantChoice")
Data Types: char
| string
Choices
— Variant choice names
cell array of character vectors | array of strings
Variant choice names, specified as a cell array of character vectors or an array of strings. Additional variant choices are also added to the new variant component, along with the active choice from the converted component.

,
code compile
, startup
,
runtime
, and inherit from
Simulink.VariantControl

More About
Definitions
Term | Definition | Application | More Information |
---|---|---|---|
architecture | A System Composer™ architecture represents a system of components and how they interface with each other structurally and behaviorally. |
Different types of architectures describe different aspects of systems. You can use views to visualize a subset of components in an architecture. You can define parameters on the architecture level using the Parameter Editor. | |
root | A root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports that surround the system of interest. | The root architecture has a system boundary surrounding your architecture model. You can add architecture ports that define interfaces across the boundary. | |
model | A System Composer model is the file that contains architectural information, such as components, ports, connectors, interfaces, and behaviors. |
Perform operations on a model:
A System Composer model is stored as an SLX file. | Create Architecture Model with Interfaces and Requirement Links |
component | A component is a replaceable part of a system that fulfills a clear function in the context of an architecture. A component defines an architectural element, such as a function, another system, hardware, software, or other conceptual entity. A component can also be a subsystem or subfunction. | Represented as a block, a component is a part of an architecture model that can be separated into reusable artifacts. Transfer information between components with:
| |
port | A port is a node on a component or architecture that represents a point of interaction with its environment. A port permits the flow of information to and from other components or systems. |
| |
connector | Connectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures. | A connector allows two components to interact without defining the nature of the interaction. Set an interface on a port to define how the components interact. |
Term | Definition | Application | More Information |
---|---|---|---|
variant | A variant is one of many structural or behavioral choices in a variant component. | Use variants to quickly swap different architectural designs for a component while performing analysis. | Create Variants |
variant control | A variant control is a string that controls the active variant choice. | Set the variant control programmatically to control which variant is active. | Set Variant Control Condition |
