When I try to compare a simulink model and its ancestor by using "compare to ancestor" in the simulink project interface I get a binary comparison of both files and not a model comparison.

What should I do to get the correct comparison ?

Check my answer below and try the process with the demo files available. If they are files of different names you want to compare there is a seperate process you can follow to compare the xml files.

Followup to previous comment. For the XML file comparison you need Simulink Report Generator. The compare to ancestor can be a bit confusing here. It does the binary comparison when you do not have the report generator, but if you do have report generator it will do the xml comparison instead.

This launches an appropriate comparison using the MATLAB Comparison Tool, comparing the modified version of the file in your sandbox against its ancestor stored in your version control tool. If you select a Simulink model, and you have Simulink Report Generator™ installed, this runs a Simulink XML Comparison.

Try doing the process on this demo to make sure everything in MATLAB/Simulink is working properly.

I tried the demo and it worked out fine comparing simulink files.

Hi, It seems form the model comparison diff report, at a time only one Item can be selected to see the highlighted portion in the Original Models. Is there a way to select all Diff Items both from left and right sides to see the complete impacted blocks highlighted in models?

Thank you.
