    Description

    example

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

    Examples

    collapse all

    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

    collapse all

    Interface to set, specified as asystemcomposer.interface.DataInterface,systemcomposer.ValueType,systemcomposer.interface.PhysicalInterface, orsystemcomposer.interface.ServiceInterface对象。通过在一个空的年代tring or character vector removes the interface on the port.

    architecture

    A System Composer™architecturerepresents 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 architecturedescribes the flow of data in a system.

    • Logical architecturedescribes the intended operation of a system.

    • Physical architecturedescribes the platform or hardware in a system.

    Compose Architecture Visually
    model

    A System Composermodelis 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.

    component

    Acomponentis 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.

    Components
    port

    Aportis 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 portsare interaction points on the component to other components.

    • Architecture portsare ports on the boundary of the system, whether the boundary is within a component or the overall architecture model.

    Ports
    connector

    Connectorsare 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.

    interface data dictionary

    Aninterface data dictionaryis 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 theInterface Editor. Interface dictionaries can be reused between models that need to use a given set of interfaces, elements, and value types. Data dictionaries are stored in separate SLDD files.

    data interface

    Adata interfacedefines 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 theInterface Editorto create and manage data interfaces and data elements and store them in an interface data dictionary for reuse between models.

    data element

    Adata elementdescribes 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.

    value type

    Avalue typecan 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 theInterface Editorso that you can reuse the value types as interfaces or data elements.

    Create Value Types as Interfaces
    owned interface

    Anowned interfaceis 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

    Anadapterhelps 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 theAdapterblock to implement an adapter.

    With an adapter, you can perform functions on theInterface Adapterdialog:

    • Create and edit mappings between input and output interfaces.

    • Apply an interface conversionUnitDelayto break an algebraic loop.

    • Apply an interface conversionRateTransitionto reconcile different sample time rates for reference models.

    • When output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.
