    Okay. One more question about the LTC3633 circuit. It seems that at the PHMODE pin INTVCC and GND seem to be shorted together through the 0 ohm resistances and that is unacceptable according to the LTC3633 datasheet?

    Hello I am trying to implement a similar power sequence scheme as in Basys in a custom PCB of mine for a bigger Artix-7 chip. My concern is what is the purpose of FDV301N transistor on page 8 of the public schematic revision D. It's base seems to be tied to RUN2 of LTC3633. RUN2 is an input so what exactly is supposed to enable the 3.3V rail in this circuit? Sincerely, Maksim Bondaruk
