Description

example

removeElement(interface,name) removes an element with name name from an interface interface.

Examples

collapse all

Add a data interface newInterface to the interface dictionary of the model. Add a data element newElement with data type double to the data interface, then remove the data element.

arch = systemcomposer.createModel("newModel",true);
interface = addInterface(arch.InterfaceDictionary,"newInterface");
element = addElement(interface,"newElement",DataType="double");
removeElement(interface,"newElement")

Add a physical interface newPhysicalInterface to the interface dictionary of the model. Add a physical element newElement with domain type electrical.electrical to the physical interface, then remove the physical element.

arch = systemcomposer.createModel("newModel",true);
interface = addPhysicalInterface(arch.InterfaceDictionary,"newPhysicalInterface");
element = addElement(interface,"newElement",Type="electrical.electrical");
removeElement(interface,"newElement")

Input Arguments

TermDefinitionApplicationMore Information
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.

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.

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.

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:

  • 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.

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