On multiple PicoZed SDR's we are observing VCCINT-0P95V at 0.919V, which is below min spec (0.93V). I traced the problem to excessive voltage drop across inductor E6. (VOUT3 is at 0.964V).
Just an observation so far, we seem to be operating fine despite the low rail.
I would use the ADM1166 margining feature to boost the rail, but I am worried about over-voltaging VCC-BRAM, which is also fed from VOUT3. VCC-BRAM is only exposed on the bottom of the SOM (E5 and C194) in the middle of the connectors, so is a difficult rail to probe.
