Add ports to architecture



ports = addPort(architecture,portNames,portTypes) adds a set of ports with specified names portNames and types portTypes.

ports = addPort(architecture,portNames,portTypes,stereotypes) also applies stereotypes specified in stereotypes to a set of new ports.

Create a model, get the root architecture, add a component, and add a port.

model = systemcomposer.createModel('archModel',true);
rootArch = get(model,'Architecture');
newComponent = addComponent(rootArch,'NewComponent');
newPort = addPort(newComponent.Architecture,'NewCompPort','in')
newPort = 

  ArchitecturePort with properties:

Input Arguments

collapse all

Architecture, specified as a systemcomposer.arch.Architecture object. addPort adds ports to the architecture of a component or the root architecture of the model. Use <component>.Architecture to access the architecture of a component.

Names of ports, specified as a cell array of character vectors or an array of strings. If necessary, System Composer™ appends a number to the port name to ensure uniqueness. The size of portNames, portTypes, and stereotypes must be the same.

Data Types: char | string

Port types, specified as a cell array of character vectors or an array of strings. Available port types follow:

  • "in"

  • "out"

  • "physical"

Data Types: char | string

Stereotypes to apply to ports, specified as an array of systemcomposer.profile.Stereotype objects. Each stereotype in the array must either be a stereotype that applies to all element types or a port stereotype.

Output Arguments

Created ports, returned as an array of systemcomposer.arch.ArchitecturePort objects.

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.

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

physical subsystemA 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.Describe Component Behavior Using Simscape
physical portA 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 a Component
physical connector

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.Architecture Model with Simscape Behavior for a DC Motor
physical interface

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 Simulink.ConnectionBus object that specifies at least one Simulink.ConnectionElement object.

Use a physical interface to bundle physical elements to describe a physical model using at least one physical domain.Specify Physical Interfaces on the Ports
physical element

A physical element describes the decomposition of a physical interface. A physical element is equivalent to a Simulink.ConnectionElement object.

Define the Type of a physical element as a physical domain to enable use of that domain in a physical model.Describe Component Behavior Using Simscape

TermDefinitionApplicationMore Information
stereotypeA stereotype is a custom extension of the modeling language. Stereotypes provide a mechanism to extend the architecture language elements by adding domain-specific metadata.Apply stereotypes to elements: root-level architecture, component architecture, connectors, ports, data interfaces, and value types of a model. A model element can have multiple stereotypes. Stereotypes provide model elements with a common set of property fields, such as mass, cost, and power.Extend Architectural Design Using Stereotypes
propertyA property is a field in a stereotype. For each element the stereotype is applied to, specific property values are specified.Use properties to store quantitative characteristics, such as weight or speed, that are associated with a model element. Properties can also be descriptive or represent a status. You can view and edit the properties of each element in the architecture model using the Property Inspector.
profileA profile is a package of stereotypes to create a self-consistent domain of element types.Author profiles and apply profiles to a model using the Profile Editor. You can store stereotypes for a project in one profile or in several. Profiles are stored in XML files when they are saved.
