Save interfaces to dictionary
saves all locally defined interfaces to a shared dictionary with additional options.
Save to Dictionary
Create a model and a shared dictionary. Add an interface to the model's interface dictionary, and add an element. Save all interfaces defined in the model to the shared dictionary.
arch = systemcomposer.createModel("newModel"); dictionary = systemcomposer.createDictionary("myInterfaces.sldd"); interface = addInterface(arch.InterfaceDictionary,"newSignal"); element = addElement(interface,"newElement",Type="double"); saveToDictionary(arch,"myInterfaces")
model — Architecture model
Architecture model, specified as a
dictionary — Data dictionary
Data dictionary, specified as a
systemcomposer.interface.Dictionary object. You can specify the default
data dictionary that defines local interfaces or an external data dictionary that
carries interface definitions. If the model links to multiple data dictionaries, then
dictionary must be the dictionary that carries interface
definitions. For information on how to create a dictionary, see
dictionaryName — Dictionary name
character vector | string
Dictionary name, specified as a character vector or string. If a dictionary with this name does not exist, one will be created.
Specify optional pairs of arguments as
the argument name and
Value is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name in quotes.
CollisionResolutionOption — Option to resolve interface collisions
Option to resolve interface collisions between the local model data dictionary and the shared data dictionary linked to the model, specified as one of these values:
systemcomposer.interface.CollisionResolution.USE_MODELprioritizes interface duplicates using the local interfaces defined in the model.
systemcomposer.interface.CollisionResolution.USE_DICTIONARYprioritizes interface duplicates using the interfaces defined in the shared dictionary.
If interface collisions are present and you do not specify a value for the
CollisionResolutionOption name-value argument, the
saveToDictionary function generates an error and prompts
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.
A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.
Perform operations on a model:
A System Composer model is stored as an SLX file.

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:
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.
These are different types of ports:
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.
|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.
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.
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:
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|
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|
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:
