in some words, my circuit is feeded from battery (VBATT). The VBATT is taken with a voltage divider for read voltage by Atmega, and is routed into a voltage regulator (from 0.8/3.2 to 3.3) VREG.
All net for voltage and GND have their names and labels (I need "only" to do the signal routes and voltage divider) as you can see.
Checking for errors, DRC errors complains with
supply pin vcc overwritten with more than one signal
This is the image (if needed I can also give sch and brd)
On board all airwires seems ok, instead.
Thank you for your effort and support.

It means exactly what is says.
You have several VCC pins. One is connected to Vbat (on the supply symbol) and the others to Vreg, that's all.
