System Composer™ provides built-in element types: components, ports, connectors, and interfaces. Create stereotypes (2) to extend element types with additional architectural metadata (5). Package related stereotypes into profiles (1) for use with multiple models. Share profiles between models to ensure consistency within a project.

Stereotypes (3) provide a template to represent certain concepts and terminologies. Assign custom stereotypes to a model element to define the element's relation to the system. Additional quantitative properties (5) defined within the stereotype with values specified on a per-element basis can be used for early analyses (4), such as budget allocation, latency tradeoffs, and other parametric design concerns. You can add engineering units to property values to establish context.
