Without having used the Cyclone, I can say that if the PCI interface is
a standard one, the pull ups/downs required are in the PCI spec (which
I strongly suggest you read). Available at:
http://www.pcisig.com/specifications
Whether you need series resistors depends ont he physical
characteristics of the drivers and the board.

Hi,everybody.
I have some questions about pci interface on Cyclone.Would someone help
me?
First,Which pins of PCI should be pull-up or pull-down on the board?
Second,Do some resistors(33ohms or 50ohms) to be series between EP1C6
and PCI?
Thanks.
