If I use 1.35V for DDR3L and 3.3V for other IOs, what should be the voltage on VCCPD rail.

Recommended operating conditions of datasheet(av_51002) says "VCCPD must be 2.5 V when VCCIO is 2.5, 1.8, 1.5, 1.35, 1.25, or 1.2 V. VCCPD must be 3.0 V when VCCIO is 3.0 V. VCCPD must be 3.3 V

when VCCIO is 3.3 V."

    Hi Sir,

    With this combination, are you able to let the Quartue compilation pass fitter?

    If it pass, then you can check the .pin file and see what voltage level should connect to the VCCPD pin.
