Multiple Pins with the Same Name
When making a part in EAGLE, you may have several pins with same name (such as multiple ground pins on a single part). EAGLE will complain if you try to name them all the same name as you can't have multiple pins with the same identifier. One way to get around this is just to name them GND1, GND2, etc. They will show up in your schematic as such. However, there is a niftier way of doing this.
While making the schematic symbol, label the redundant pins using the @ symbol. GND@1, GND@2, GND@3.... NC@1, NC@2, NC@3.... and so forth.
When you make the device from its schematic symbol and PCB footprint the name@numeral format will still appear on the schematic symbol for the device. Associate the name@numeral pins with the appropriate pins on the pcb footprint. You will still see the full name@numeral designation in the schematic symbol editor and in the library device editor. However....
When you place the part on an actual schematic, the @numeral suffix will be dropped from all pins. The schematic will show the part as having multiple pins all named GND, NC, etc.
If you liked this tip, gimme some rep!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
