The FMC HPC0 (J5) and FMC HPC1 (J4) VADJ pins are wired to the programmable rail
VADJ_FMC_BUS. The VADJ_FMC_BUS rail is programmed to 1.80V by default. The VADJ_FMC
derivative rail powers the XCZU9EG HP banks 64 - 67 (refer to

Monitoring Voltage and Current

Voltage and current monitoring and control are available for the Maxim power system
controllers through the Maxim PowerTool graphical user interface. The on-board Maxim
InTune power controllers listed in
PMBus connector J84, which is provided for use with the Maxim PowerTool USB cable
(Maxim part number MAXPOWERTOOL001#), which can be ordered from the Maxim
website [Ref 21]. The associated Maxim PowerTool GUI can be downloaded from the Maxim
website. This is the simplest and most convenient way to monitor the voltage and current
values for the Maxim PMBus programmed power rails listed in
Each PMBus programmable Maxim controller programmable is capable of reporting the
voltage and current of its controlled rail to the Maxim GUI for display to the user. A subset
of the programmable rails and two fixed rails have a TI INA226 PMBus power monitor circuit
with connections to the rail sense net and taps on a series current sense resistor. This
arrangement permits the INA226 to report the sensed parameters on the PMBus. The
subset of rails configured with the INA226 power monitors is shown in
