Author, analyze, and manage requirements within System Composer™ using Requirements Toolbox™. Create rich text requirements or import them from external sources. View the requirements and design together, establish links for allocated or derived requirements, annotate diagrams with requirements content, analyze the traceability of requirements, and navigate between requirements and designs.

Edit and manage requirements using the Requirements Editor (Requirements Toolbox). Link requirements to components and ports in a System Composer architecture diagram. Interactively link requirements using the diagram, link from an external document selection, and update reference requirement links to make them locally available in the model. A Requirements Toolbox license is required to activate these features.

Use Simulink^® Test™ to perform requirement-based testing workflows that include inputs, expected outputs, and acceptance criteria. You can create a test harness for a System Composer component to validate simulation results and verify design in the Test Manager (Simulink Test). A Simulink Test license is required to activate these features.
