PCIe Switch implementation on FPGA

Hi, I want to implement a PCIe Switch with one Upstream and with four Downstream port one lane each. My question is can I locate all four diffrential pairs pins in one IO-Bank using one clock. T...

There's no way anyone can answer this question. You have not mentioned the FPGA device you are planning to use.

Please use Quartus to answer this question; instantiate the PCIe cores and synthesize the design. If Quartus lets you do it, then you can :)

Note that you don't have to put logic on the fabric side of the interface, just drive signals to valid logic levels. When I've done this with ALTGX components, they are preserved (even though the logic does nothing).

Cheers,
