Hi, We are using Intel Cyclone FPGA having part number 5CGTFD7C5U19A7N in our board. Is it necessary to provide power supply to VCCIO7A and VCCIO8A rails for the proper functioning of FPGA..? Thanks & Regards, Vyshnav

Hi Vyshav,

The VCCIO power is not monitored by the POR circuitry (reference page no: 322) , so it nos necessary to provide the voltage
