Hi Thomas,
This is great, I also like the way you generated that plot with matplotlib.
How about instead of building special diode classes using a dict like this for
the models?
d_1N914 = {'IS':'2.52n', 'RS':0.568, 'N':1.752, 'CJO':'4p', 'M':0.4, 'TT':'20n'}
Then to use the model:
cct.Dx = eispice.D(1, eispice.GND, area=1, **d_1N914)
I can't think of any real advantage to using dictionaries instead of classes,
but it would line up a little closer with traditional spice model definitions.
I think I prefer converting into Python code like you're doing as opposed to
keeping models in spice and running right away after the conversion. That way
you can make hand modifications to the model if you want, and save it for later
when it can be loaded with an import command, i.e.
import mylib.diodes.D_MURS120 # (or something like that)
I've been thinking about eventually having a separate eispice library package,
this is a great step in that direction.
Thanks!
Charles
