Hi Pat,
This is a little different than the original question but will
the PI tool allow to check for IR drop across the distribution
path to make sure that the last load has enough voltage to
operate properly or that overboost of the regulator output
to compensate for same wont provide too much V for the
first load. I have run into a couple of situations where this
has caused problems on Very low voltage (say 1Vish) and
high currents for the loads in the path. Thanks.
It's digital logic power so what could possibly happen, ryt?
Obligatory and global ;-) 8-P
Best Regards,
Michael C. Greim
