There was a thread with this subject line last September. Steve Knapp from Xilinx responded in the thread as follows:
"I have a separate document that I will send you that includes all the relevant PCI 3.0 timing and which parameters that you can ignore if you're on the same PC board."
I sent Steve an email last week but haven't gotten a response yet. If anyone has a copy of this document I'd much appreciate a copy. You can send it to email@example.com.
By the way, anybody running PCI in Spartan-3 at 66MHz? If so, which core are you using?
Thanks, Bob S.
