FDTD Modeling with Passive Shielding for Crosstalk Reduction in Coupled RLC Interconnects

This paper presents passive shielding technique for crosstalk noise and delay reduction in resistive driven RLC interconnect. FDTD technique is used for modeling proposed geometry. The worst case delay and noise induced due to crosstalk in passive shielded interconnects are compared with unshielded lines and is validated using HSPICE simulations for 32nm global interconnects. From the results it has been demonstrated that the proposed model results and HSPICE simulations differ by 8% and by using proposed geometry crosstalk noise and delay has come down by 90% and 52% when compared to unshielded line.
