How do we compare simulink models to find differences

I would like to compare two simulink models to find differences. I would expect that there is a utility that does that and highlight the modified sections.

Moving the blocks should not be a trigger as the exact loactions of the blocks is not important.

The changes to the logic and avriables should be highlighted as done in all the C compilers on the market.

There used to be a comparator built in for the XML results but it has disapeared from the 2012B version.

Anybody know a way to tell what changed in my files from the earlier saved version?

Thank you

There is an XML comparator that is part of Simulink Report Generator. Unfortunately I don't believe you can tell it not to notice difference in block position as it is recorded in the XML and will show as a difference.

You may also use the Diff and Merge tool of ikv++technologies ag - medini unite. http://www.ikv.de/index.php/en/products/unite

DiffPlug can do Simulink comparisons, and you can configure it to ignore position (or any other property you don't care about).
