Thank you! I am using the MC analysis option now. I have not found a
way to specify the THD as the evaluated function for MC/WC; the only
working method I've identified is to tell PSpice to output the results
of all the MC runs, and then look myself at the FFT graphs.. Would be
great to be able to script somehow finding the minimax of THD w.r.t. a
set of part values (resistances) (i.e. minimum wrt resistances of the
maximum wrt bjt variations)...
