@User: That script will do an extraction of caravel from magic but with the I/O cells "black-boxed". Then it runs LVS on the top-level (gate level) verilog, but first reading in the SPICE subcircuits for all the standard cells and primitive devices from the PDK, so that the LVS will be done down to the transistor level.

@Tim Edwards Looks like a pretty comprehensive script. There may be a few LVS issues that aren't included yet, but maybe you've updated the script. Looks like you've logged most, if not all, of the problems I've encountered. Here's my summary of the device name/type/parameter discrepancies. https://github.com/google/skywater-pdk/issues/276

@Mitch Bailey: Thanks, that issue is pretty comprehensive. I merged one of my recent issues into it.
