is there any nice way to compare simulink model files to
highlight changed blocks??

Hi David,
There is a very nice (and expensive) way to compare Simulink models,
it's a tool called SimDiff (http://www.ensoftcorp.com/SimDiff/
Overview.gen.html). The way I usually compare 2 Simulink models is to
just open them up in any diff utility and look through the
differences. Since the model files are just ASCII text files this
works quite well if there aren't too many changes.

HTH,
Ashish.

yeah, i do that also... unfortunately these models are
huge and with even small changes they are hard to sort out
with normal diff tools, especially if the only diffs are
block locations.

David,

If you are ever in a pinch and you really need to know what changed ASAP you
can get a free trial of SimDiff at:

A new program called ecDIFF can highlight changed blocks and also report a list of model differences for documentation and review. It is available through FunctionSIM.

Hey David,
The program ecDIFF has been crunching through 100MB+ mdl files in search of differences, will output them in a list and display them graphically. It is available through FunctionSIM.

Hi David,

medini unite may help you to compare two simulink models.
You can easily filter graphical information to show only the "real" differences of
your models.

There is a free trial available at:
