Eagle power trace on 2 layers with vias
« on: October 30, 2013, 05:57:06 am »
I am making a pcb which needs more trace width and want to place the power traces on both layers overlapping and vias connecting the 2  from place to place.
1 layer routing works ok but for the 2 nd layer eagle won`t allow routing the same trace only if I disconnect from the schematic and put wire.
is there a workaround for this?

I am a hobbyist so perhaps some more professional can help you better but what i usually do:
You can manually place a "wire" on the pcb wherever you want on which layer you want, you just have to "name" it the same labelname as the power trace and then you can manually place as many via's as you want. But it is totally seperated from the normal "route" way of doing.

This works but when placing a wire it says can`t backannotate this operation. please do this on the schematic.
if I close the schematic it severs the connection and I can`t add any other parts/traces.

But there is nothing to backannotate because you don't alter the schematic, you alter the pcb design, if you rename the wire to the powerlabel it should all be fine. If you place a wire eagle gives it a new netname but that should be altered by you to the exact same name as the trace on the other side.

You may have missed it but there is a separate area for Eagle. Maybe you should take this where it rightly belongs?

If I need to do something like this, I usually just rip-up a trace near where I want to connect to, and run the second trace, then reconnect the ripped up trace.

Then just hit vias on the trace as needed. No need to name them if you place them on the centre of the trace.
