I call this kind of nets as AVCC and DVCC. When I have more than one supply net I call them AVCC1, AVCC2, etc. I know this is a bit uncommon, because you have to have a table somewhere (at least one in your mind) which links which supply is what. AVCC2=5V, AVCC1=12V etc. Same goes for ground connections. AGND and DGND.

Re: gEDA-user: Voltage symbols and Spice
Different places have different standards, but it is not that uncommon to use the Blah Blah A designation in some form to indicate an analog supply as opposed to a digital supply. If you really want to get folks frothing about conventions, just bring up the split ground planes vs solid ground plane.

gEDA-user: Voltage symbols and Spice
I am trying to use the "generic-power.sym" in my schematic. I am setting the net attribute to 5VA (for 5V analog). I was hoping this would make all the nets with such a symbol. When I try to run gnetlist with the spice-sdb backend I get this error printing out several times. Got an invalid net= attrib [net=5VA] Missing : in net= attrib The nets don't appear connected in the spice file. Do folks have any suggestions on how to solve this?
