Hi,
the drs or constraints, as they are named in more recent releases, are saved in an xml file: https://de.mathworks.com/help/codeprover/ug/xml-format-of-drs-file.html
If you have two of these xml files, you could use the MATLAB comparison tool to compare them: https://www.mathworks.com/help/matlab/matlab_env/comparing-files-and-folders.html
Best regards,
Tjorben
