Hi, i want to use eMMC 5.1 IC with Artix-7 200T, which bank of FPGA is recommended. can i use Gigabit Transciever bank (i.e. bank 216) for this purpose? and can we use Gigabit transciever bank for normal GPIOs?
No, you cannot use the Gbit pins for an eMMC interface or for GPIO pins. To figure out which banks and pins to use you'll have to reference the Artix-7 data sheet DS181 and take a look at UG471 to understand more details about the I/O behaviors on 7-Series FPGAs.
