gEDA-user: Power nets in hierarchy

[Bill Cox <bill@viasic.com>]

Hi.

I'd like to have a device type like 'power' for power bus symbols like 
vdd and vss.  Rather than trying to overwrite the name of the net 
connected to these symbol's pins, I'd like to leave them alone until 
after flattening.  Then, I can have a simple pass that changes the name 
of power nets to that of the power symbol.  I would merge multiple 
instances of such nets at this time.

This is different functionality that that given with the 
net=<netname>:<pinlabel> attribute.  That attribute assigns pins on 
footprints to signals, even when they are not available on the symbol. 
Power devices would globally override nets after flattening, but would 
have no effect until then.

What do you think?

Bill
