Hello,
I want to design a PCB for FPGA prototyping. Please help me understand if I need to supply these voltages and why?
Vref
Vrefp
Vin
These voltages are from the Artix-7 Datasheet. I'm using the Artix - 7 236 pin BGA FPGA. I'm only using the FPGA for gigabit ethernet purpose, no LCD screen, no SUB, no other peripherals.
Your help is much appreciated.
