How to lock code generation support for specific simulink models/subsystems?

Is it possible to lock specific models e.g. from a library for code generation to avoid reuse in productive code - only use them in Simulink simulations?

Hi Simon, can you give more details for what exactly you are looking for?

Hi Simon, I understand you want to protect a simulink block/model so that it is only used during simulation and is not used while code generation.

Simulink provides a feature called "Model Protection" that allows you to lock models and restrict their usage. Here is how you can use it:

1. Open the model that you want to lock in Simulink.
2. Go to the "Model Block" tab in the Simulink Editor.
3. You will find the "Protection" section.
4. In the "Protection" section, check the relevant options (Simulate / Generate Code) .
5. Optionally, you can set a password to further restrict access to the locked model. Enter the password in the "Password" field.
6. Click "OK" to save the changes and lock the model.

Once the model is locked, it cannot be modified or regenerated for code generation. However, it can still be used for simulations within Simulink.

Thanks for your response.

But as far as i understand - the model protection is only for referenced models. The other option as you described,to protect the full .slx file ... but that is also not my intention.

In my case, i created (and work with) a own customized simulink library with various masked library blocks inside (in different levels of abstraction for some functionalities) - and i want only some of this library blocks (high level abstraction blocks) lock against code-generation (or even poping up an error if used in code-generation) to avoid in my team to use the wrong models for use e.g. in the rapid prototyping....
