: Please grab the latest versions of magic, netgen, and open_pdks. I spent a lot of time over the weekend and into yesterday fixing some major issues that cropped up during the run-up to the first MPW tape-out. Early on, I discovered that large digital standard-cell layouts were taking forever to run through LVS, and I introduced a "quick hack" solution which I only got around to analyzing thoroughly yesterday. I now have a fixed version of netgen that resolves that issue, although it depends on an updated setup file for sky130 on netgen. If after the update, you still have issues with LVS, then send me an example.
