Spartan3 pci above 33MHz

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 snipped-for-privacy@sandel.com.



By the way, anybody running PCI in Spartan-3 at 66MHz? If so, which core are you using?



Thanks, Bob S.

I have just sent you the file that I was sent.

At about the same time I wanted to find a dev board where a SPARTAN could control a PCI CONNECTOR so that I could do FPGA to something where I had bought the something on a PCI card. I never found one so I designed it, SPARTAN 3, 32bit PCI CONNECTOR, RS232 some SDRAM, LEDs and switches.

I haven't used a core. If you are doing point to point PCI which your post suggests then you don't want most of the features it would give you. I haven't even done parity as the chip I'm talking to can be told to ignore it.

However 25MHz gets me all the bandwidth I need at the moment.
