Software Architecture Modeling

Model and simulate AUTOSAR software architecture (requires System Composer™)

An AUTOSAR architecture model provides resources and a canvas for developing AUTOSAR composition and component models. From the architecture model, you can:

  • Add and connect AUTOSAR compositions and components, or import a composition from ARXML files.

  • Create profiles, stereotypes, and views for architecture analysis.

  • Link components to requirements (requires Requirements Toolbox™).

  • Define component behavior by creating, linking, or importing Simulink® models.

  • Configure scheduling and simulation.

  • Export composition and component ARXML descriptions and generate component code (requires Embedded Coder®).

Architecture models provide an end-to-end AUTOSAR software design workflow. In Simulink, you can author a high-level application design for the Classic or Adaptive Platform, implement behavior for application components, and simulate the application. For classic architecture compositions, you can add Basic Software (BSW) service calls and service implementations.
