Crosstalk modeling for coupled RLC interconnects with application to shield insertion

On-chip interconnect delay and crosstalk noise have become significant bottlenecks in the performance and signal integrity of deep submicrometer VLSI circuits. A crosstalk noise model for both identical and nonidentical coupled resistance-inductance-capacitance (RLC) interconnects is developed based on a decoupling technique exhibiting an average error of 6.8% as compared to SPICE. The crosstalk noise model, together with a proposed concept of effective mutual inductance, is applied to evaluate the effectiveness of the shielding technique.
