Setup a Simulink model to work only with a license file

Hi,
I would like to setup a Simulink model to work only in presence of a license file.
This license file shall have an expiry date, such that the Simulink model does not work when the license is expired.
Is there a way to implement such a feature in Simulink?
Thanks.
Best regards

Hi Alessandro,
Without having a valid license MATLAB and Simulink can't be installed, so if you try to run the model without a valid license, it will not run.
Thanks,
Utkarsh

Hi,
thanks for the answer. Actually I am meaning a different thing. I am not talking about Mathwork's license for running Simulink, but an ad-hoc license (of mine) for running a Simulink model.
Example: assume such a feature exists, I would be able to create a Simulink model and associate an ad hoc license file to it; then I then I could send the model and the ad hoc license file to another person. In this way, I would be able to impede that people without the ad hoc license file can execute the model, and ensure that only people with the ad hoc license file can.
Note: the license file shall not be Mathworks' license file but any suitable file (e.g. containing a key) allowing doing it.

I think that you want to protect your model. You can use the following four approaches to protect the intellectual property of a Simulink model:
  1. Protected Model
  2. S-Function Target
  3. Shared Library
  4. Read/Write Access for Subsystems
Please refer to the following link to get more information about these methods: https://www.mathworks.com/matlabcentral/answers/414694-how-can-i-protect-the-intellectual-property-of-my-simulink-model
