Hi everyone, I am trying to optimize the parameters for each device in my schematic. After some googling around I found this link http://www.h-renrew.de/h/python_spice/optimisation.html I also found some tutorials on how to do local optimization using cadence, but not much info on spice. How do I do it using ngspice/xschem?

Maybe for a first insight go to Chapter 23 "Circuit optimization with ngspice" in the ngspice user manual.
