Hi Nick, thank you for review. I have added a description and charts regarding the PLD values in go/custompldrequirement. Basically, I traced each port in schematics, searched for it in board layout, and compared it with ports on actual physical device.

Do you think I should add a hw engineer as reviewer to verify these positions?
