Yes.  Report(NetLength), added 2007-03-03 by djdelorie.
I have used it to phase a clock fan-out.

I'm curious as to what sort of structures and if they are ones supported 
by wcalc (wcalc.sf.net).

Yes -- on an upcoming project I'm going to need to make some equal-distance RF 
waveguides, and having a feature like this would be a great help with that!

gEDA-user: pcb question: matching differential lines

2008-09-06 Thread jean,,,
Greetings to everyone here. 

I'm working on a new board and I have a couple differential lines in my
design.  Is there anyway in pcb to measure the length of the traces and
see how different they are?  I'd like to have them match up as close as
possible instead of just eyeballing it.
