Hallo,
It is sometimes hard to choose the good ferrite material or the good size (1812 instead of 1008) for the different inductors involved in a filter (ie: for the transfo and inductors involved a group delay equalizer...).
Micrometals and other manufacturers give Q curves but they don't provide spice models or Sdata. It would be nice to be able to use a fix or tuneable inductance value (ie:250nH) while using a ascii file to define its Q at different frequencies (freq,Q). Genesys would interpolate between these frequencies and keep the last Q value for upper frequencies.

What you're asking about is akin to high level modeling, where you do not really mind the "why/how it works?", just the fact that it does.
Although this is an "easy" way to do it, it detracts from fully understanding why it does work. Which to me is key when you're doing circuit design. There are few models out there for ferrites and such, and you would normally take one that fits your application and fit the model to the data provided by the manufacturer. This gives good insight into how it works, and when it doesn't; why it does not.
