So i made this Open source Board, With three separate switching regulator for each bank VCCIO on 4 Layer Gold finish board with most of microZed pins broken out in LVDS pair. PCB is 4 Layer impedance control for 100R LVDS pair. Board has 3 solder jumpers per regulator to change bank voltage of each bank separately.
There is not much in schematic , only few switching regulator for all Bank Voltage and IO headers .
