Requirements Traceability

Link requirements to designs, code, and tests, specify relationships, add markup, review traceability to models and code, check consistency

Create requirement links to establish traceability to model elements, test cases, test harnesses, MATLAB^® code lines, data dictionaries, Stateflow^® elements, System Composer™ architecture models, and other requirements. Specify the link type to convey the nature of the relationship, such as a model element that implements a functional requirement or a test harness that verifies a test specification requirement. Create custom requirement and link types to extend the default linking capabilities.

Use the Requirements Editor to create and view links, and use the Requirements Perspective to view requirements in the model context.
