Extraction of the capacitance matrix of multiconductor interconnection lines for high-speed IC system design

A simplified and very effective method for the extraction of the capacitance matrix of multiconductor interconnection lines for high-speed integrated circuit (IC) system design is described in this paper. Because of the combination of the approximate spatial domain Green's function of multilayered dielectric media and the three physically meaningful charge basis functions per conductor edge, preprocessing can take place. Thus, the capacitance matrix can then be quickly computed with high accuracy. Examples show that this method is very efficient and accurate for circuit parameter extraction of high-speed IC interconnect structures
