Hi. I recently (well, a year ago now) came across this

https://github.com/RobertBaruch/polychip

In theory it can be used to construct a netlist (or something that looks like 
it) from inkscape chip drawings. I made some adjustments so that it would 
understand certain constructions in the VIC-II chip (and others) and also made 
some speed improvements. The fork is at https://github.com/michielboland/polychip

Some years ago I got bored and drew the polysilicon and diffusion traces on the 
visual6502.org 8565R2 die shot. In fact I started with the metal layer, but then 
I figured that did not actually contain the interesting bits. But obviously if 
you want some sort of automated processing you need metal as well, and contacts 
too. So that kept me busy for a while last month. But the result is now 
something that looks like a netlist of the 8565R2. In theory you could use this 
as an input for a visual6502-like visualizer, but I got a bit bored with it now 
so maybe someone else wants to look at this? (If at all possible, obviously the 
analog bits won't work.)

A processed 8656R2 drawing is here:

Note that this is oriented with the output section at the bottom right, like the 
older VIC-II die shots)

Highlighted parts should display a title if you hover over them. I'm not aware 
of official net names so I mostly made stuff up based on various documents.

Ground and power are omitted, the color of the transistor should indicate what 
is on the other side of it (blue=vcc, teal=ground, purple=pull-up, pink=diode, 
white=pass transistor or part of complex gate)

Cheers
Michiel
