Manage requirements and architecture model together in the Requirements Perspective from Simulink® Requirements™. Select Apps > Requirements Manager.
When you click a component in the Requirements Perspective, linked requirements are highlighted. Conversely, when you click a requirement, the linked components are shown.
To directly create a link, drag a requirement onto a component.
You can close the annotation that shows the link as necessary. This does not delete the link.
You can exit the Requirements perspective by clicking the perspectives menu on the lower-right corner of the architecture model and selecting Exit perspective.
For more information on managing requirements, see Manage Navigation Backlinks in External Requirements Documents (Simulink Requirements).
