We do the full schematic thing for even the tiniest boards.

I've probably asked before, but what did you say your schematic capture tool
of choice is?

We never autoroute, and almost always go with the pins as originally
assigned on the schematic, ie no pin or gate swapping.

Is that because... you're thinking the particular pin or gate used might have
been done so for a reason?

In general I find pin and gate swapping of great help, and the guy who entered
the schematic can just set the appropriate attribute if he doesn't want the
pin or gate swapping enabled for the net in question.

We use ORCAD and PADS for production PCBs, but have no path to back-annotate
reference designator changes in PADS back to the schematic (other than doing
it manually, of course). We've occasionally looked around at third-party
tools such as Prescience to do this, but no one ever had enough time to do a
serious eval.
