Hello guys, Can anyone please suggest guideline for routing the PCI signal from fpga to the connector.
Thanks in advance, regards williams
Guideline for PCB routing for PCI signal

If you're building a daughtercard (as opposed to a motherboard) you should follow the maximum lengths per the PCI specification. Also note that the clock line is a length matching spec, not just a maximum. Briefly, the bulk of the 32-bit signals spec 1.5" max to the connector. Clock is 2.5" (matched length), and the 64-bit extension signals spec
2" maximum. Exceptions include interrupt lines and the reset signal.With any luck your FPGA pinout helps you meet these requirements.
