MosFet "LEVELS" in LTSpice compared to other spice simulators

 

Hello,


I am getting confusing hints from search results: ..

So a mosfet "level" is a way to model a mosfet using a set of defined parameters. (?)

There are many so called "levels" and there have been numbers assigned to them, without this meaning that one is necessarily an evolution of the previous. I see on this manual for example (http://ecee.colorado.edu/~mathys/ecen1400/pdf/scad3.pdf) that ltspice can understand at least 10 of these levels.


1)Is this numbering kept same across LTSpice, PSpice, HSpice?

2)Do all simulators use all the parameters with the same name or are they free to introduce/remove/mix parameters?

3)Will LTSpice complain if we pass to it a parameter name that it cannot understand in a model, or just ignore it without reporting?

4)Is there some solid documentation on ALL of the ltspice mosfet levels?


Any hints welcome, thanks!
