You can create an HTML or Word report of the differences between two Simulink models using the ‘comparison’ output argument of the visdiff function (R2017b or newer).
For example, you can try something like this
>> comparison = visdiff(model1, model2);
>> % Publish the results of the comparison to a file:
>> reportFile = publish(comparison, 'Format', 'HTML', 'Name', 'myreport.html')
For more information, see the ‘Publish Comparison Report’ section of the visdiff documentation page:
