Add components to an architecture model
Use a Component block to represent a structural or behavioral element at any level of an architecture model hierarchy. Add ports to the block to connect to other components. Define an interface for the ports and add properties using stereotypes.
To add or connect System Composer™ components:
Add an architecture Component block from the Modeling tab or the palette. You can also click and drag a box on the canvas, then select the Component block.
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 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 add component-level parameters, use the Parameter Editor tool.
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.
Physical — Physical connection to another component
If you connect to another component, the physical 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. You can represent specific architectures using alternate views.
Different types of architectures describe different aspects of systems:
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 physical subsystem is a Simulink® subsystem with Simscape™ connections.
A physical subsystem with Simscape connections uses a physical network approach suited for simulating systems with real physical components and represents a mathematical model.
|Implement Component Behavior Using Simscape|
A physical port represents a Simscape physical modeling connector port called a Connection Port (Simscape).
Use physical ports to connect components in an architecture model or to enable physical systems in a Simulink subsystem.
|Define Physical Ports on Component|
A physical connector can represent a nondirectional conserving connection of a specific physical domain. Connectors can also represent physical signals.
Use physical connectors to connect physical components that represent features of a system to simulate mathematically.

A physical interface defines the kind of
information that flows through a physical port. The same interface can be assigned to multiple
ports. A physical interface is a composite interface equivalent to a
Use a physical interface to bundle physical elements to describe a physical model using at least one physical domain.
|Specify Physical Interfaces on Ports|
A physical element describes the
decomposition of a physical interface. A physical element is equivalent to a
