Model Checks for Requirements Links
To check that every requirements link in your model has a valid target in a requirements document, from the Simulink Toolstrip, open the Requirements app. Click Check Consistency to run the Requirements Consistency Checking checks in the Model Advisor.
In the Model Advisor, the requirements consistency checks are available in:
By Product > Requirements Toolbox > Requirements Consistency
By Task > Requirements Consistency Checking
For more information about these Model Advisor checks, see Requirements Consistency Checks (Requirements Toolbox)
When modeling for high-integrity systems, to check that model elements link to requirement documents, run Check for model elements that do not link to requirements.
