Simulink® Requirements™ provides you with Implementation Status rollups for your requirement sets. You can use these status rollups to identify gaps in requirement implementation in your design. Requirements that have the link type set to Implemented by contribute to the Implementation Status rollup metric.
The Implementation Status metrics for a requirement set are cumulatively aggregated over all the requirements in the set. Each child requirement belonging to a parent requirement must be implemented for the parent requirement to be considered as implemented.
You can view the Implementation Status metric for your requirement sets from both the Requirements Editor and the Requirements Browser in the Requirements Perspective View. To toggle the metric display, select Display > Implementation Status from the Requirements Editor menu. You can update the Implementation Status metric for all the requirement sets you have loaded in the Requirements Editor by clicking the icon in the toolbar. Hover your mouse over the Implemented column in the Requirements Editor or Requirements Browser for each requirement or requirement set to view the Implementation Status metric associated with it.
