But noise on the ground plane means the voltage drop between ground and +1.xV is not stable, and not reliably above 1.yV as well as causing general noise induced errors, so if it is just a matter of not maintaining the sufficient voltage drop due to the ground level bobbling up and down, then pumping up +V would fix that. The voltage drop would be too high most of the time, but not when ground is +0.15V or whatever on one particular chip for an instant.And 1.5V is not really an option, but a test...
However: If that works, it probably means that our voltage drop is too high but the noise is not that much of an issue.
That should be an easier fix.
