AUTOMATIC-GENERATION OF ANALYTICAL MODELS FOR INTERCONNECT CAPACITANCES

An analytical-model generator for interconnect capacitances is presented. It obtains analytical expressions of self and coupling capacitances of interconnects for commonly encountered configurations, based on a series of numerical simulations and a partial knowledge of the flux components associated with the configurations. The configurations which are currently considered by this model generator are: a) single line; b) crossing lines; c) parallel lines on the same layer; and d) parallel lines on different layers (both overlapping and nonoverlapping).
