This is the original netlist for that cell. It seems that the automatic parsing script that generated that spice file cut off one of the terminals. In general, I would not use that

cells

folder. Like I mentioned earlier, there seems to have been some repository merging/transferring artifacts, because both repositories do not currently contain what I would expect them to. That

folder is outdated at best. That's at the top of my list to fix as soon as possible.
