Create and connect two ports in System Composer™.

Create a top-level architecture model.

modelName = "archModel";
arch = systemcomposer.createModel(modelName);
rootArch = get(arch,"Architecture");                  

Create two new components.

names = ["Component1","Component2"];
newComponents = addComponent(rootArch,names);

Add ports to the components.

outPort1 = addPort(newComponents(1).Architecture,"testSig","out"); 
inPort1 = addPort(newComponents(2).Architecture,"testSig","in");

Extract the component ports.

srcPort = getPort(newComponents(1),"testSig");
destPort = getPort(newComponents(2),"testSig");

Connect the ports.

conns = connect(srcPort,destPort);

View the model.


Improve the model layout.

TermDefinitionApplicationMore Information

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.


The root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports surrounding 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


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.

  • Attach 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

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:

Compose Architectures Visually


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


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.
