You mean between = gnetlist and PCB. A good use for the requested neutral netlist format. = But I don=92t see how back annotation could play well with hierarchy. = What happens if the same segment in different instances of a subcircuit = has different properties, for example?

It would read = in a unpackaged gschem netlist =

Also = BOM.

and  write out the PCB file formats so it = would be loosley coupled to gschem and tightly coupled to PCB. =
