Subversion and mdl files

3 views (last 30 days)
Hello
Does anybody know how to have real "merge" action between two .mdl files? Specifically if you are using subversion version control how can we handle a .mdl file share between two users? Thanks

There is a third-party application known as SimMerge (<http://www.ensoftcorp.com/SimMerge/Overview.gen.html>) that is quite helpful for this. (I'm a user, not affiliated with the company.) It's a bit expensive, but well worth the cost if working on a team. It supports two- and three-way diff and merging as you would expect with any other source code management tool.

Thanks Stuart. I did look into the SimMerge tool and it should od the trick. Probaly will only be able to implement it next year as the cost, as you said, is high.

Hi Carlo,
I'm not aware of a way to do this. However, an alternative would be to break apart your model into multiple .mdl files and use model reference to combine them. This would allow different users to work on their own separate pieces of the model, and not have to worry about merging later.
This approach is also useful in that it allows you to test smaller components of your model individually.
Hope this helps! -Jarrod

Hi Carlo,
Check out the release notes for the latest version of Simulink (look under "Model Management"):

Hello Jarrod,
Thanks for the hint. It's not what I am looking for, even though it would limit the impact.

In general, doing text merges on ".mdl" files doesn't go well, so I would strongly advise against this. The primary issue is that text in ".mdl" files isn't as "local" as text in a regular source code file would be. As a result, text in one part of a model file may also influence the meaning of text elsewhere in the model. It isn't as convenient, to be sure, but it is probably best to configure your version-control system to treat ".mdl" files as binary even though they are text-based.

medini unite also provides SIMULINK model merge capabilities. It can be integrated in a number of SCM tools, such as CVS, SVN, ClearCase, Visual Source Safe and more. You can request a trial here http://www.ikv.de/mediniunite/
