@User: Not supported in any mode. See, however: https://github.com/google/skywater-pdk/issues/309. This is ongoing work and I think Brad Minch is now working on getting the wafer-level (process) statistics working. Also the script needs to be walking the "models/" directory as well as the "cells/" directory, but I think for mismatch, this gets much more complicated because the AGAUSS() lines need to be inside the model itself for ngspice to apply a new random value for every instance of the device. For places where the mismatch {} block are not in the same cell as the model (which is everything down the "models/" path), some complicated bookkeeping will be required. But it's a start.
