An Unconditionally Stable FDTD Model for Crosstalk Analysis of VLSI Interconnects

In this paper, an unconditionally stable finite-difference time-domain (US-FDTD) model is proposed for the crosstalk noise analysis of coupled very large scale integration interconnects. The accuracy of the proposed model is validated against the conventional FDTD model and HSPICE. It is observed th...

Description
Summary:In this paper, an unconditionally stable finite-difference time-domain (US-FDTD) model is proposed for the crosstalk noise analysis of coupled very large scale integration interconnects. The accuracy of the proposed model is validated against the conventional FDTD model and HSPICE. It is observed that the proposed model is as accurate as the conventional FDTD and HSPICE. It is also observed that the stability of the proposed model is not constrained by the Courant-Friedrichs-Lewy stability condition. Depending on the time-step size, the proposed model can be up to 100× faster than the conventional FDTD.
