setInterface

Set interface for port

Since R2019a

Syntax

setInterface(port,interface)

Description

setInterface(port,interface) sets the interface for a port.

Examples

Set Interface for Port and Remove Interface on Port

Create a model and get the root architecture.

model = systemcomposer.createModel("archModel",true);
rootArch = get(model,"Architecture");

Add a component and add a port to the component.

newComponent = addComponent(rootArch,"newComponent");
newPort = addPort(newComponent.Architecture,"newPort","in");

Add a data interface and set the interface for the port.

newInterface = addInterface(model.InterfaceDictionary,"newInterface");
setInterface(newPort,newInterface)

Remove the data interface on the port.

newPort.setInterface("")

Input Arguments

port — Port

port object

Port, specified as a systemcomposer.arch.ArchitecturePort or systemcomposer.arch.ComponentPort object.

interface — Interface

data interface object | value type object | physical interface object | service interface object | empty string | empty character vector

Interface to set, specified as a systemcomposer.interface.DataInterface, systemcomposer.ValueType, systemcomposer.interface.PhysicalInterface, or systemcomposer.interface.ServiceInterface object. Passing in an empty string or character vector removes the interface on the port.

Term	Definition	Application	More Information
architecture	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.	Compose Architectures Visually Author Parameters in System Composer Using Parameter Editor
model	A 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. A System Composer model is stored as an SLX file.	Create Architecture Model with Interfaces and Requirement Links
component	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: Port interfaces using the Interface Editor Parameters using the Parameter Editor	Components
port	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: 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
connector	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.	Connections

interface data dictionary	An interface data dictionary is a consolidated list of all the interfaces and value types in an architecture and where they are used.	Local interfaces on a System Composer model can be saved in an interface data dictionary using the Interface Editor. You can reuse interface dictionaries between models that need to use a given set of interfaces, elements, and value types. Linked data dictionaries are stored in separate SLDD files.	Manage Interfaces with Data Dictionaries Reference Data Dictionaries
data interface	A data interface defines the kind of information that flows through a port. The same interface can be assigned to multiple ports. A data interface can be composite, meaning that it can include data elements that describe the properties of an interface signal.	Data interfaces represent the information that is shared through a connector and enters or exits a component through a port. Use the Interface Editor to create and manage data interfaces and data elements and store them in an interface data dictionary for reuse between models.	Create Architecture Model with Interfaces and Requirement Links Define Port Interfaces Between Components
data element	A data element describes a portion of an interface, such as a communication message, a calculated or measured parameter, or other decomposition of that interface.	Data interfaces are decomposed into data elements: Pins or wires in a connector or harness. Messages transmitted across a bus. Data structures shared between components.	Create Interfaces Assign Interfaces to Ports
value type	A value type can be used as a port interface to define the atomic piece of data that flows through that port and has a top-level type, dimension, unit, complexity, minimum, maximum, and description.	You can also assign the type of data elements in data interfaces to value types. Add value types to data dictionaries using the Interface Editor so that you can reuse the value types as interfaces or data elements.	Create Value Types as Interfaces
owned interface	An owned interface is an interface that is local to a specific port and not shared in a data dictionary or the model dictionary.	Create an owned interface to represent a value type or data interface that is local to a port.	Define Owned Interfaces Local to Ports
adapter	An adapter helps connect two components with incompatible port interfaces by mapping between the two interfaces. An adapter can act as a unit delay or rate transition. You can also use an adapter for bus creation. Use the Adapter block to implement an adapter.	With an adapter, you can perform functions on the Interface Adapter dialog box: Create and edit mappings between input and output interfaces. Apply an interface conversion UnitDelay to break an algebraic loop. Apply an interface conversion RateTransition to reconcile different sample time rates for reference models. Apply an interface conversion Merge to merges two or more message or signal lines. When output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.	Interface Adapter Adapter
