That one is strange .... I don't know why it was 2*T0.
Some regressions changed. The new results look like probably an
improvement, so I updated that, updated testing status of
d_poly_cap, and pushed to unstable.
Thanks.
This one was the last of the attempts to port spice models using
modelgen. I think the errors happened because I was interrupted
for some time, then when I went back to it forgot where I was.
This is the one that convinced me that this is not the way to do
it, prompting the development of spice_wrapper as a hopefully
better way to port spice models.
