This is the Aruba CX simulator community, so your question is a bit misplaced.
Your request for help requires more time and resources you can expect from a community like this. Perhaps you could reach out to a local Aruba partner to get help?
As a starting point you also need to look into how the proposed connections are. The drawing look like you want to connect 10G and 1G interfaces. It will not work, you need to have the same speed on connected interfaces.
4G total in to your core from access switches look like it may be a bad way to wire it together.
