star grounds?
« on: July 04, 2019, 05:14:44 am »
I was wondering how to make star grounds in Eagle 7...


probably on a similar note, I find myself sometimes wanting to have a different name for a net without putting something like a 0 ohm resistor in

thanks

No idea if there's a way to achieve this in Eagle 7, but the general method would be to place a fake 0R resistor to connect two different nets, and short this resistor out in the layout when everything else is done (will create a DRC error).

Edit: I remember someone created a special component to achieve this - just two (or n) different pins in the schematic symbol, but shorted by solid copper in the component package footprint.

Yeah, I that's what I've been doing but was hoping there was a less kludgy way of going about it... I've been using a cutable trace since it doesn't take much physical space

Well, you can get one of these made.  A physical star ground component.  I found it inside an old Sony piece.  Never saw anything like it before.

You can draw a component that has a few SMD pads that link together with a bit of copper layer.
It might toss some DRC warnings, but you can make a star ground go to one point with different net names.
