Add components with alternative designs
Use a Variant Component block to create multiple design alternatives for a component.
To add or connect System Composer™ components:
Add an architecture Variant Component block from the Modeling tab or the palette. You can also click and drag a box on the canvas, then select the Variant Component block. You can also create a variant component from a component or reference component. Right-click on the component and select Add Variant Choice.
To add a port, select an edge of the component and choose a direction from the menu:
Click and drag the port to create a connection. Connect to another component. You can also create a new component to complete the connection.
To connect Variant Component blocks to architecture or composition model root ports, drag from the component ports to the containing model boundary. When you release the connection, a root port is created at the boundary.
To manage Variant Component choices:
By default, two variant choices are created when you create a Variant Component block. Right-click the Variant Component block and select Variant > Label Mode Active Choice, then select the active choice.
To add an additional variant choice, right-click on the Variant Component block and select Variant > Add Variant Choice.
Double-click into the Variant Component block to design the variants within it.
Use the Variant Manager to easily switch between variant choices in a complex model hierarchy. Right-click on the Variant Component block and select Variant > Open in Variant Manager. For more information, see Variant Manager for Simulink.
Source — Input connection from another component
If you connect to a source component, the interfaces on the ports are shared.
Destination — Output connection to another component
If you connect to a destination component, the interfaces on the ports are shared.
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.
A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.
Perform operations on a model:
A System Composer model is stored as an SLX file.

A component is a nontrivial, nearly independent, and 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, a 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:
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.
There are different types of ports:
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.
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.
A variant control is a string that controls the active variant choice.
Set the variant control to programmatically control which variant is active.
