Get default stereotype for elements

Since R2021b



stereotype = getDefaultElementStereotype(stereotype,elementType) gets the default stereotype stereotype of the child elements whose parent element of type elementType has the stereotype stereotype applied.

Create a profile for latency characteristics and save it.

profile = systemcomposer.profile.Profile.createProfile("LatencyProfile");

latencybase = profile.addStereotype("LatencyBase");

connLatency = profile.addStereotype("ConnectorLatency",...

nodeLatency = profile.addStereotype("NodeLatency",...

portLatency = profile.addStereotype("PortLatency",...

Specify the LatencyProfile.NodeLatency stereotype as a component stereotype. Set the default component stereotype.

nodeLatency.AppliesTo = "Component";

Get the default component stereotype on nodeLatency.

stereotype = getDefaultElementStereotype(nodeLatency,"Component")
stereotype = 

  Stereotype with properties:

                    Name: 'NodeLatency'
             Description: ''
                  Parent: [1×1 systemcomposer.profile.Stereotype]
               AppliesTo: 'Component'
                Abstract: 0
                    Icon: 'default'
    ComponentHeaderColor: [210 210 210]
      ConnectorLineColor: [168 168 168]
      ConnectorLineStyle: 'Default'
      FullyQualifiedName: 'LatencyProfile.NodeLatency'
                 Profile: [1×1 systemcomposer.profile.Profile]
         OwnedProperties: [1×1 systemcomposer.profile.Property]
              Properties: [1×3 systemcomposer.profile.Property]

Input Arguments

Data Types: char | string

Stereotype, specified as a systemcomposer.profile.Stereotype object.

Output Arguments

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.


The root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports surrounding the system of interest.

The root architecture has a system boundary surrounding your architecture model. You can add architecture ports that define interfaces across the boundary.

Compose Architectures Visually


A System Composer model is the file that contains architectural information, such as components, ports, connectors, interfaces, and behaviors.

Perform operations on a model:

  • Extract root-level architecture.

  • Apply profiles.

  • Attach 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

A component is a 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, another 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:

Compose Architectures Visually


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.

  • 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. The root architecture has a boundary defined by its ports.

Compose Architectures Visually


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.

Stereotypes provide a mechanism to extend the core language elements and add domain-specific metadata.

Apply stereotypes to core element types. An element can have multiple stereotypes. Stereotypes allow you to style different elements. Stereotypes provide elements with a common set of properties, such as mass, cost, and power.


A property is a field in a stereotype. You can specify property values for each element to which the stereotype is applied.

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.


A profile is a package of stereotypes.

You can use profiles to create a domain of specialized element types. Author profiles and apply profiles to a model using the Profile Editor. You can store stereotypes for a project in one or several profiles. When you save profiles, they are stored in XML files.
