I'm running into more property errors with netgen which I can't explain and which appear to be as simple as swapping transistors. I'm also confused though because the comp.out file refers to the exact same two devices twice (M27 in the schematic and M40 in the layout) but extracts different lengths in the two error lines. I've double-checked both the layout and schematic files and it should be able to match the two dummy devices: one of the dummy devices has length 1um and the other has length 4um. I've attached the comp.out file and the two netlist files in the comments.

It looks exactly like the situation that I corrected in a previous commit to netgen, so I must have missed something.

Yeah, I had already pulled your previous commit, so this must be something else.

It's similar, but before I was specifically solving for the case of capacitors, which are set up a bit differently because you can't add widths together like transistors. So it looks like something I did for sorting property values for capacitors ended up breaking the sorting for property values of transistors.

Awesome thanks!

Well, sorry about the mess I made of that previous update. It's no fun spending time trying to figure out what's wrong with your circuit only to finally decide it's the tool that's screwing up.

No problem, I really appreciate your responsiveness to these issues.

I know you're under a tight deadline. : )
