As printed circuit conductors are popularly used, the modelling of the electrical behaviour of these interconnect is getting attention. The authors present a method by which SPICE compatible lumped equivalent circuit can be extracted from two-dimensional FEM simulation of transmission line interconnects in a fast and efficient manner. The lumped parameters of the transmission line are obtained by applying a certain type of moment matching to the FEM results. It will also be pointed out that the impedance has only stable poles even though there are unstable poles in both the inductance and the resistance.
