makeVariant

Convert component to variant choice

Syntax

[variantComp,choices] = makeVariant(component)

[variantComp,choices] = makeVariant(component,Name=Value)

Description

[variantComp,choices] = makeVariant(component) converts the component component to a variant choice component and returns the parent Variant Component block object variantComp and available variant choice components choices.

[variantComp,choices] = makeVariant(component,Name=Value) converts the component component to a variant choice component with additional options and returns the parent Variant Component block object variantComp and available variant choice components choices.

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)

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.

Example: [variantComp,choices] = makeVariant(newComponent,Choices=["NewVariantChoiceA","NewVariantChoiceB","NewVariantChoiceC"])

Data Types: char | string

ChoiceLabels — Variant choice labels

cell array of character vectors | array of strings

Data Types: char | string

VariantControl — Variant control expression

true or false (default) | boolean condition expression | a Simulink.VariantExpression object representing a boolean condition expression

Variant control expression, specified as boolean expression. The active variant choice is determined based on the evaluation of the boolean expression. The variant component created is in expression mode.

Example: [variantComp,choices] = makeVariant(newComponent, VariantControl = ‘V==1’)

Data Types: char | string

VariantActivationTime — Variant activation time

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.	Compose Architectures Visually Author Parameters in System Composer Using 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.	Compose Architectures Visually
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: Extract root-level architecture. Apply profiles. Link interface data dictionaries. Generate instances from model architecture. 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 interfaces using the Interface Editor Parameters using the Parameter Editor	Compose Architectures Visually
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.	Component ports are interaction points on the component to other components. Architecture ports are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model. The root architecture has a boundary defined by its ports.	Compose Architectures Visually
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.	Compose Architectures Visually

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
