More information about the power system regulator components can be found at the Infineon Integrated Circuits website.
The FMCP HSPC (J51 and J53) VADJ pins are wired to the programmable rail VADJ_FMC. The VADJ_FMC rail is programmed to 1.50V by default. The VADJ_FMC rail also powers the XCVM1802 FMCP interface banks 706, 707, and 708 (see the table in I/O Voltage Rails). Documentation describing PMBus programming for the Infineon power controllers is available at the Infineon Integrated Circuits website. The PCB layout and power system design meet the recommended criteria described in the Versal Adaptive SoC PCB Design User Guide (UG863).
