[pci] 3.3V to 5V bus problem

[Marco Buffa <marcobuffa@lombardiacom.it>]

Hi,
I have a trivial problem designing a PCI board with the PCI bridge 
implemented on a Xilinx Spartan IIE.

The problem is that this FPGA (3.3V) is not 5V tolerant, but I suppose 
the PCI bus signals are 5V scaled. (Is it correct? I can't find any 3.3V 
PCI bus connector, with the correct keyways, on my mother-board)

Did someone know the solution?

Thank's.
