VREF

Hi

1) Is there option to define which VREF the FPGA use ? (interal FPGA vref or external IO pin )

If yes - where should I define it in the Quartus

2)Do all the banks should get same vref ?

3)How can I make same vref value when I transfer SERDES data from FPGA to other ( each FPGA locate in other board)
