Hi Paul, Originally posted in cdnusers.org by CharlieE
I guess what you didn't know yet, is that the ground (and power) symbols task is To Name The Net! What they do, is say ""This net is a ground net, and has the name earth_ground."" So, when you then try attaching ANOTHER name to the net, the software has to say, 'Which name do I use?' and in this case says 'I use the ground symbol.'
If you need to have nets named something else, and then connect it to your ground net CHGND, then use and ALIAS or SYNONYM part to make that connection. If you wanted the net to be CHGND from the beginning, then rename the symbols name to CHGND.
