PCI Express

I want to know PCIE I/O standard in virtex-6,who can tell me?

PCIe uses the GTP or GTX high-speed dedicated signals.  You can't change the IO standard

for these pins.  It uses CML (current-mode logic) differential signalling.  PCIe requires capacitive

coupling between transmit and receive pairs.  The capacitors are located near the transmitters.
