Transient analysis of crosstalk in PCB interconnects including process variation

This paper addresses the generation of an enhanced transmission line model for the transient analysis of long bus-like interconnects with the inclusion of parameters uncertainties. The proposed approach is based on the expansion of the well known frequency-domain telegraph equations in terms of orthogonal polynomials and on the back conversion to time domain via Fourier superposition. An application example involving the crosstalk analysis of a PCB coupled-microstrip interconnect with uncertainties in the relative dielectric permittivity and trace separation concludes the paper.
