Normally I just connect the power supply pin(s) of each chip to a "power 
port" (fourth button down, right-hand toolbar), selecting a different 
pin name for each power rail.   This works perfectly for me.   It sounds 
like you're doing the same, but since it doesn't work for you I presume 
you're doing something different.   If it helps, my last board used VCC, 
VAA, and GNDPWR.

Regards,

Robert.
