Netlist looks like this $PACKAGES footprint_symbol_name ! device_type ; REF1 REF2 $NETS NET1 ; REF1.1 REF2.1 $END For each device type you'll need a file called devicetype.txt . If you have the footprint symbols created, you can dump the device file from the footprint and just rename it. Jean Bratton Senior PCB Designer Freedom CAD Services, Inc.

I want to create a 3rd party netlist file (i.e. not schematic driven), and the Help mentions the "Transferring Logic Design Data user guide in your documentation set" (in yellow below). Does anyone know where this "documentation set" is located, or have an example format for a netlist file?
