After trying some solutions, I've managed to solve the problem using the suggestion from https://www.mathworks.com/matlabcentral/answers/1590659-code-generation-information-file-does-not-exist
Basically you have to set the path from your Mathworks Workspace the same of your Simulink Model file saved.
So in my case MATLAB workspace path was ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1434593/image.png)
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1434593/image.png)
And I've saved the Simulink .slx file on the same path C:/Teste![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1434598/image.png)

And then it works like charm.
Thanks,
