Models
Hi Folks,
on the model front, the issue as I see it with the
current model implementation is (unless you've fixed
it) that at the end of each model there's a bunch of
code to adjust each calculated current source, and
then add it or subtract it in to the correct places
in the matrix. It's getting the correct sign, and
applying it to the right place in the matrix, as
well as performing the correct adjustment that I
found difficult in my model implementation. It seems
to me that for each conductance or transconductance
in a model, all that work should be part of the
simulator, not part of the model. That way, all the
model implementer has to do is come up with the
right value of current and linearized
(trans)conductance for a given set of input conditions,
i.e. terminal voltages and rates of change of terminal
voltages.
Cheers,
Alan
