I've done some PCB work before, but never anything too challenging - a basic linear power supply board with LM317s and basic caps/through-hole resistors, so on. All stuff that was easy and in the parts library of ExpressPCB. Mostly, though, I'm used to IC workflow.
Now, though, I find myself trying to cad up a design involving a few off-the-beaten-path parts. Some specific ADCs from National and Analog, a filter from Maxim, and so on. Stuff that I can't easily find schematic symbols for. In fact, I can't find the AD7685 symbol in ANY format.
So my question is what's YOUR PCB workflow? Specifically, what do you do about schematic symbols and footprints?
