Define Profiles and Stereotypes
To verify structural and functional requirements, you must capture nonfunctional properties on elements in an architecture model. For example, if there is a limit on the total power consumption of a system, the model must capture the power rating of each electrical component. This requires extending built-in model element types with properties corresponding to requirements, in this case, an electrical component type as an extension of components. You can introduce a self-consistent domain of model element types into System Composer™ using a group of property sets, or stereotypes, called a profile.
System Composer provides these architectural model elements to describe an architecture model:
Component
Port
Connection
You can view the properties of each element in the architecture model using the Property Inspector. Open Property Inspector using View > Property Inspector.
You author profiles using the Profile Editor. Profiles are saved separately from the architecture model and are available to all architecture models.
When you create a profile, you define:
Stereotypes — Customize built-in model element types
Property sets — Add analysis properties to an architecture model element
Data types, dimensions, etc — Define property values
You can define stereotypes to extend built-in elements and capture additional data about
an element. Element stereotypes define the class of the elements to which they apply. For
example, a MechanicalComponent stereotype with properties such as
Weight and Volume applies only to components.
A stereotype does not have to define a class. For example, a
ProjectItem stereotype can add generic properties such as catalog number
or unit cost, a BorrowedItem stereotype can add properties such as
BorrowedSource and ReturnDeadline. A model element can
have multiple stereotypes.
Stereotypes can extend other stereotypes to include their properties. For example, a
UserInterface stereotype can be an extension of a
SoftwareComponent stereotype, and add a property called
ScreenResolution.
You can collect stereotypes in profiles.
Create a Profile and Add Stereotypes
Create a profile to define a set of component, port, and connection types to be used in an architecture model. For example, a profile for an electromechanical system, such as a robot, could consist of these types:
Component types:
Electrical component
Mechanical component
Software component
Connection types:
Analog signal connection
Data connection
Port types
Data port
Define a profile using the Profile Editor. In any architecture model, select Architecture > Profile > Profile Editor. Click New Profile. Select new profile to start editing.
Name the profile and provide a description. Add stereotypes by clicking New
Stereotype. You can delete stereotypes and profiles by clicking 
in their respective menus.
Save the profile. The file name is the same as the profile name.
Add Properties with Stereotypes
Select a stereotype in a profile to define it:
Name — The name of the component type, for example,
ElectricalComponent.Applies to — The model element type to which the stereotype applies. This field can be an architecture, component, port, connector, or interface. You can apply this stereotype only to a model element of this type.
Icon — Icon to be shown on the model element.
Base stereotype — Other stereotype on which this stereotype is based. This can be empty.
Abstract stereotype — A stereotype that is not intended to be applied directly to a model element. You can use abstract stereotypes only as the base stereotype for other stereotypes.
Add properties to a stereotype using 
. Define these fields for each property:
Property name — Valid variable name
Type — Numerical, string, or enumeration data type
Unit — Value units as a string
Default — Default value
Add, delete, and reorder properties using the property toolstrip:
You can create a stereotype that applies all model element types by setting the Applies to field to <nothing>. With these stereotypes, you can add properties to elements regardless of whether they are components, ports, connectors, or architectures.
Default Stereotypes
Each profile can have a set of default stereotypes. Use default stereotypes when each new element of a certain type must assume the same stereotype. System Composer applies a default stereotype to the root architecture when you import the profile. You can set this default in the Profile Editor using the Stereotype applied to root on import field.
This default stereotype is for the top-level architecture. If a model imports multiple profiles, the default component stereotype for all profiles apply to the architecture.
Each component stereotype can also have defaults for the components, ports, and
connections added to its architecture. For example, if you want all new connections in an
electrical component to be analog connections, set AnalogConnection as a
default stereotype for the ElectricalComponent stereotype.
After you import the profile into a model, all new connections assume the
AnalogConnection stereotype.
Stereotype-Based Styling
Profiles and stereotypes are used to apply custom metadata on the architecture model elements. Element styling is an additional visual cue that indicates applied stereotypes
You can use provided icons for the component stereotypes or use you own custom icon
images. Custom icons support .png, .jpeg, or
.svn image files of size 16-by-16 pixels. The custom icons are
displayed as badges on the components for which the stereotypes are applied.
You can associate a color with component stereotypes. Element styling is an additional visual cue that indicates applied stereotypes.
Use a preconfigured set of color options for component stereotypes to style the architecture component headers. You can use a preconfigured set of color options for component stereotypes to style the architecture component headers. Below is an example that displays the applied component stereotypes with icons and color. See Use Stereotypes and Profiles to learn how to use stereotypes in your model.
Similarly, you can style architecture connectors using the stereotype settings. You can style connectors by using connector, port, or port interface stereotypes. Customize styling provides various color and line style choices. Connector styles are also reflected in architecture and spotlight views.
