Examples

Create and connect two ports in System Composer™.

Create a top-level architecture model.

modelName = 'archModel';
arch = systemcomposer.createModel(modelName,true);
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.

systemcomposer.openModel(modelName);

Improve the model layout.

Simulink.BlockDiagram.arrangeSystem(modelName)

Definitions

TermDefinitionApplicationMore Information
architectureA 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:

  • Functional architecture describes the flow of data in a system.

  • Logical architecture describes the intended operation of a system.

  • Physical architecture describes the platform or hardware in a system.

Compose Architecture Visually
modelA System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.

Perform operations on a model:

  • Extract the root-level architecture contained in the model.

  • Apply profiles.

  • Link interface data dictionaries.

  • Generate instances from model architecture.

System Composer models are stored as SLX files.

Create an Architecture Model with Interfaces and Requirement Links
componentA 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 architecture 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.Components
portA 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:

  • 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.

Ports
connectorConnectors 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.Connections
