Hi Jim, You've got a problem if you're intending to go as far as the schematic for a netlist. That you'll be building from scratch, and you'll be spending the extra time trying to 'sync' it to the layout. That will probably account for 70-80% of your time if you go that route. I'd done plenty of reverse (or inverse) engineering of layout. Never wanted to go for schematic connectivity, and as never asked for it. If you've got the gerbers and a 'generic, "was" built BOM' you're set. The gerbers will transfer into Allegro fairly easy (might take a little trial and error to determine the settings), and cleanup is all that's required past that. Cleanup most likely will involve that plane layers, but that's what gerbers give you. As for connectivity, I don't see the need unless you're being paid the extra cash to make it happen, and I do hope this is a moonlighting job. Good day.
