Requirements Definition

Author requirements, create requirements from external documents, and define requirements hierarchy

You can create requirements from within Simulink®, by using the Requirements Browser pane or the Requirements Editor. Add detailed text, images, and keywords to describe requirements. Add child requirements to specify lower-level functionality. Add context to your model by showing requirements and descriptions on the Simulink canvas.

If you have requirements documented externally, import requirements to Simulink from Microsoft® Word or Microsoft Excel® documents. You can revise requirements by using the Requirements Editor, or by synchronizing changes from the external document.
