Thanks, I will check those links.
Whether it's schematic to PCB or netlist to PCB doesn't matter, LTspice's schematic encoding is proprietary so would require a dedicated script. But that would be redundant since the netlist already contains that information in a format closer to traditional layout software. But a schematic version would be more flexible.
I have been doing freehand layout, but I need a ratsnest to cut down on errors, or else a very methodical manual error checking procedure.

With my limited experience with traditional SPICE netlists, I estimate an 
awk script that produces a netlist pcb can read would take maximum 4 horus 
to develop, minimal testing included.

This wouldn't add compontents obviously, as there's no footprint 
information available.

It also wouldn't solve your undisclosed problems with the rats.

Regards,

Igor2
