Speaking of relevance to the discussion, I highly doubt the PO is using something as expensive as Mentor Graphics' Pads.
You are turning the PO's original discussion into a "my dad can beat up your dad" conversion. Suck up your pride and agree that this guy is obviously not a professional with the required software to literally "do everything for him" and he should probably do it himself.
Real engineers don't need these tools and if you still disagree I can almost guarantee I can model anything relevant that software can with my own state space equations.
I said that is what I use for tinkering because it is free, not what I have seen by PCB professionals (again relevance to PO and what he is probably using).If your experience with autorouting ends with packages such as Eagle or Kicad then you are playing in the bush leagues using amateur tools.
