I was thinking in another option to provide .CIF inductors from a .tek file based on process stack-up that is the ASITIC tool. I used in the past and had acceptable variations compared to Momentum. Since it use lumped equivalent circuit models maybe can be useful to provide an "inductor generation flow", or to use the first run to characterize some inductors in order to create better models for next runs... @User did you use or have any feedback comparison with fastsolvers?
