Dear community,

I must protect the intellectual property of a Simulink Model. I have already generated a Model Reference Protected (a new feature of Simulink 7.4) that works very well. But now I want to introduce in my model an expiration date, just like a temporary license.
Do you have any suggestion to do this?

Thank you

I don't believe that is possible. I would suggest that you raise an
ehnacement request at:
http://www.mathworks.com/support/bugreports/

Click on "report a bug" (top right corner). Choose "technical support" under
"select type of request," and then "request an enhancement".

As far as I know this capability does not exist. I agree with Arnaud's
suggestion of contacting technical support; you can get a definitive
answer, perhaps some workarounds, and submit an enhancement request.

Some possible workarounds:

- Include a switch in the protected model that disables it if the
current date is past the expiration date.
- Issue a command to delete the mdlp file is the expiration date has passed.

These approaches might still be bypassed. Technical Support may be able
to provide some more details in possible workarounds.
