You can continue to use the legacy Requirements Management Interface (RMI):
Simulink® Requirements™ includes the RMI available with versions 2017b and later.
Simulink Check™ retains the legacy RMI interface version R2017a and earlier. See Simulink Verification and Validation Transition.
You can use the RMI to:
Associate model-based design elements with requirements.
Create links between model-based design elements.
Navigate from model-based design elements to requirements in external requirements documents.
Navigate from an embedded link in a requirements document to the corresponding model-based design element.
Review requirements links in your model by using highlighting and tags that you define.
Create reports showing which model objects link to which requirements.
