The IDS0 block computes the drain-source current of a MOSFET. Depending on the modeling level, a different algorithm is being used. The equations for each of these algorithms are programmed in functions, called MOSeq1 .. MOSeq3 that implement the particular model in question. These functions have been carefully documented to make it easier on future developers to add additional models of their own by providing corresponding MOSeq_i functions.
