I have a schematic where I've created and named a net for each pin on a controller. I now want to tie one of those pins ("enable") to ground, but I don't want the name of the net to change to "GND", it needs to stay "enable".
Can you please tell me how to assign two names into one net? (without putting a 0R resistor between the two :-) )
Thanks,
DougM

Well... you can't. But there is a workaround to accomplish your goal.
Use a short from the shorts library. The symbol is essentially two pins
connected to each other, and the package is overlapping pads. This
generates an overlap DRC error which can be safely approved.
Wire one side of the short to your controller, and the other side to ground.
This method is often used to connect multiple grounds (DGND, AGND, GND2,
etc) to a single ground (GND) potential. There's plenty of threads in
this forum about connecting two grounds.
There is a thread about this titled "Merging nets" that was started on
03-Apr-2011. You can download a SHORTS library from Olin Lathrop at
http://www.embedinc.com/pic/dload.htm. I took Olin's library and added
a few packages to it myself on an as-needed basis.
