When you open a Simulink® model that does not have internally
stored requirements links, the RMI tries to load requirements links
.req file — either the default file
or a previously specified file. If that file does not exist, the RMI
assumes that this model has no
To explicitly load requirements links from an external file:
Select Analysis > Requirements Traceability > Load Links.
The Select a file to load RMI data dialog box opens, with the default file name or the previously used file name loaded into the File name field.
Select the file from which to load the requirements links.
Click Open to load the links from the selected file.
Caution: If your model has unsaved changes to requirements links and you try to load another file, a warning appears.
