VDDHIGH_IN supply for i.MX6Q

Hi,

Does VDDHIGH_IN input supply for i.MX6Q required to be monotonic during rise time?

Any specifications on that?

In my design, VDDHIGH_IN is supplied by PMIC MMPF0100ANES VGEN5 (2.8V).

With just connection to the i.MX6Q input supply, a dip during the VDDHIGH_IN is observed.

Is this expected behavior?
