The ZCU111 evaluation board uses power management ICs (PMIC) and power regulators from Infineon
[Ref 26]
to supply the core and auxiliary voltages listed in
Table: Power System Devices
. See schematic 0381811.

The FMCP HSPC (J26) and VADJ pins are wired to the programmable rail VADJ_FMC. The VADJ_FMC rail is programmed to 1.80V by default. The VADJ_FMC rail also powers the XCZU28DR HP banks 65 and 66 (see
Table: I/O Voltage Rails
). Documentation describing PMBus programming for the Infineon power controllers is available at the Infineon website
[Ref 26]
. The PCB layout and power system design meets the recommended criteria described in the
UltraScale Architecture PCB Design User Guide
(UG583)
[Ref 4]
.
