Introduction: 
As semi-conductor industries embark to the giga hertz era, correct modeling and simulation of digital circuit that incorporate inductance becomes indispensable issue.  Simple RC extraction and simulation can no longer cope with the ever-increasing operating frequencies.  With the introduction of more metal layers, lowered operating voltage, thinner and longer interconnect wires for global signals and clock distribution seem to even aggravate the inductance effect.  Inductance effect impacts various aspects in digital design in terms of propagation delay, degradation of signal integrity due to undershoots, overshoots and oscillations, and increasing power gird noise and worsening signal cross talk.  However, due to the long-range effect of inductance, simulating the dense partial inductance matrix is difficult and impractical when applying simulation to entire chip.  A recent proposed circuit element K [1], which defined as inverse of partial inductance matrix L, has properties reminiscent of capacitance extraction such as locality and stability.  Based on K-method matrix sparsification technique, we developed a robust, efficient, and accurate extraction tool that could directly extract multi-conductors system into K circuit compliance circuit simulation tool, QuickHenry and can be simulated by INDUCTWISE [2]. The experimental results show that circuit extracted under K-method that simulate using INDUCTWISE has over 146X speedup compared to Tanner SPICE with less than 0.1% error.
