Yea - I wish I had the time to write one which understands differential impedence, matched lengths etc.

Perhaps one exists, I don't know as I try to only use open source.

I am pretty sure that I saw some ads for a commercial PCB cad program that showed functionality for exactly that.

But yes ... probably not open source.
