On the other hand, if that common part was a separate tool using a canonical netlist format, every flow involving a layout program that can export an as-built netlist could use it. All you’d need is a translator from each tool’s export format to the canonical format. Igor has a short cut for pcb, but that short cut is not available to any other flow.

No you were clear. I started writing replies to a bunch of stuff the
other night and just now started re-reading and sending. I hit send on
the wrong one. sorry.
