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 25]. The PCB layout and power system design meets the recommended criteria described in the UltraScale Architecture PCB Design User Guide (UG583) [Ref 4].
