Crosstalk characterization of high-speed interconnects in time-domain

Abstract

As the edge rate becomes faster in digital signals, signal integrity (SI) analysis, such as reflection, delay, and crosstalk becomes increasingly important. This paper proposes an efficient modeling approach, which combines the finite-difference time-domain (FDTD) method and multi-conductor layer peeling technique for differential transmission lines, to extract the equivalent model and the characteristic impedance of the differential transmission lines. These extracted models can be employed to predict the crosstalk of the high-speed signals.
