Hello @monchito911,
Have you checked the provided documentation to install and run the Model-Based Design Toolbox for S32G chips?
Please check the following links:
Model-Based-Design-Toolbox Main page, for S32G chips support check HCP:

Where you can find the following:
NXP Model-Based Design Tools/HCP How to: in here you can see that the version you downloaded is in fact correct, and in the same page from which you downloaded the zip file you can find the documentation I mentioned before:

In this guide you will see how to install the MATLAB package and you will also see an example on how to debug a PIL target in section 2.3 A “Hello World” Example, page 26.
This being an urgent topic I recommend you posting your questions in the MBDT community as we can only support you with basic MBDT information in the S32G community.
Let me know if this information was helpful.
