Eagle QuickTip: Identical Pin Names

If you’ve ever tried to make a footprint in Eagle with more than one GND, VCC, VDD, NC, etc., pin, you might have noticed that you can’t have two pins with the same names, and you ended up having to name all your GND pins GND1, GND2, GND3, etc.  If you’re mildly OCD like me, this is irksome, but thankfully there’s an easy workaround to this in Eagle.  When defining your schematic symbol and naming each pin, rather than naming pins GND1 take the common name that you want to appear in your schematics and append it with @n.  For example.  GND@1, GND@2, GND@3.  This ensures that each pin has a unique name, but they will all render as GND when placed on your schematic.  Read on to see an image of the the schematic symbol defined for the power pins above (an LPC4350 for the overly curious).

  1. Eureka!

    Thank you so much for this! I must have the same OCD that you do.

  2. Eagle version 6 also supports assigning multiple pads to the same pin which makes for even nicer schematics.
