What are you trying to do here?

What these symbols do is to give a net a name. That=92s all. Naming the =
net connected to a pin GND connects it to all other nets named GND. If =
you have more than one such symbol, and the names don=92t match, =
gnetlist will choose the first one it sees.

Is your net connected to anything?
