Get Started with System Composer

Design and analyze system and software architectures

System Composer™ enables the specification and analysis of architectures for model-based systems engineering and software architecture modeling. With System Composer, you allocate requirements while refining an architecture model that can then be designed and simulated in Simulink®. 

Architecture models consisting of components and interfaces can be authored directly, imported from other tools, or populated from the architectural elements of Simulink designs. You can describe your system using multiple architecture models and establish direct relationships between them via model-to-model allocations. Behaviors can be captured in sequence diagrams, state charts, or Simulink models. You can define and simulate the execution order of component functions and generate code from your software architecture models (with Simulink and Embedded Coder®).

To investigate specific design or analysis concerns, you can create custom live views of the model. Architecture models can be used to analyze requirements, capture properties via stereotyping, perform trade studies, and produce specifications and interface control documents (ICDs).


How to Create Compositions in System Composer
Sketch hierarchical system and software decompositions of components using a familiar component, port, and connector modeling approach.

Extend Your Architecture with Domain-Specific Design Data
Add custom properties to architectural elements using stereotypes.

Spotlight Views in System Composer
Automatically create Spotlight views in System Composer that show the context of a specific architectural component.

How to Create and Link Simulink Components
Create, link, and manage Simulink behavioral components and interfaces as part of your top-down architecture design.
