In particular, gsch2pcb right now I think needs to know too much about pcb, its file formats, library paths, etc. What I'd like is to generate a file which tells pcb - instantiate U1 which is a SO8, device type = <some vendor #>, and here are the pin names to use: 1 -> NC 2-> IN-, 3-> IN+, etc. Then I want pcb to have to figure the rest out. It seems with some planning that this intermediate file, similar to the ECO files used by pads, could have a pretty long life without a need for lots of incremental changes. -Dan --
