How to get more detailed information about spatz

[YiZhi_W]

Hello! I'm a student studying RVV, and I'm very interested in spatz. I have obtained some materials about spatz, including papers, materials in the github repository, PPT on the official website, etc. however, I found that the documentation provided in the github repository is not comprehensive. The introduction in the papers also has some differences from the current hardware design.
I want to know the hardware design details of spatz and how spatz works with snitch. Could you please provide me with more detailed documentation? It will be very helpful to me. 
Thank you very much!
