addComponent

Add components to architecture

Syntax

components = addComponent(arch,compNames)

components = addComponent(arch,compNames,stereotypes)

components = addComponent(___,Name=Value)

Description

components = addComponent(arch,compNames) adds a set of components specified by the names compNames.

To remove a component, use the destroy function.

components = addComponent(arch,compNames,stereotypes) applies stereotypes specified in stereotypes to the new components.

components = addComponent(___,Name=Value) specifies options using one or more name-value arguments in addition to the input arguments in previous syntaxes.

Examples

Create Model with Two Components

Create a model, get the root architecture, and create components. Arrange the layout to view both components.

model = systemcomposer.createModel("archModel");
systemcomposer.openModel("archModel");
arch = get(model,"Architecture");
names = ["Component1","Component2"];
comps = addComponent(arch,names);
Simulink.BlockDiagram.arrangeSystem("archModel");

Input Arguments

arch — Architecture

architecture object

Architecture, specified as a systemcomposer.arch.Architecture object.

compNames — Names of components

cell array of character vectors | array of strings

Name of components, specified as a cell array of character vectors or an array of strings. The length of compNames must be the same as stereotypes.

Data Types: char | string

stereotypes — Stereotypes to apply to components

cell array of character vectors | array of strings

Stereotypes to apply to components, specified as a cell array of character vectors or an array of strings. Each element is the qualified stereotype name for the corresponding component in the form "<profile>.<stereotype>".

Data Types: char | string

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is 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.

Example: comps = addComponent(arch,compNames,Position=[100 100 200 300])

Position — Position of component on canvas

numeric vector

Position of component on canvas, specified as a vector of coordinates, in pixels [left top right bottom].

Each vector specifies the location of the top left corner and bottom right corner of the component, specified as a 1-by-4 numeric array. The array denotes the top left corner in terms of its x and y coordinates followed by the x and y coordinates of the bottom right corner.

When adding more than one component, you can specify a matrix of size N-by-4, where N is the number of components being added.

Data Types: numeric

Output Arguments

components — Created components

array of component objects

Created components, returned as an array of systemcomposer.arch.Component objects.

Definitions

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
Root	A root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports that surround 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
Model	A System Composer model is the file that contains architectural information, such as components, ports, connectors, interfaces, and behaviors.	Perform operations on a model including extracting root-level architecture, applying profiles, linking interface data dictionaries, or generating 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 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 port interfaces using the Interface Editor, and parameters using the Parameter Editor.	Compose Architectures Visually
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.	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
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.	Compose Architectures Visually

Stereotype	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.	Define Stereotypes and Perform Analysis for Mobile Robot Extend Architectural Design Using Stereotypes Change Stereotypes Based on Stereotype Hierarchy in Portable Blender Architecture
Property	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. For more information, see Use Property Inspector in System Composer.	Set Properties Add Properties with Stereotypes Set Properties for Analysis
Profile	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.
