I've never used the CMI (Common Model Interface), but
my impression is that the CMI facility can allow one to
define their own custom models defined in C or C++ which
can be called from within an Hspice deck. As far as defining
some arbritrary math function in C, and then accessing that
function from Hspice to apply to a model parameter, I'm not
sure you can do that. I'm thinking that you cannot. Perhaps
someone from Synopsys can comment with a definitive answer.
Is the math of the function you are trying calculate such that
it can't be performed within the spice deck in a .param statement ?
