of the signal frequency component that is transmitted, the wave nature of the prop-

agated signal must be modeled, otherwise signifi cant errors may result. Wires will

thus have to be modeled as transmission lines to avoid errors during signal analysis.

Discontinuities in these transmission lines (due to various factors such as capaci-

tive loads, vias, wire bends, package pins, crossover wires, and non-ideal receivers)

can result in impendence mismatches. Such mismatches will create noise as a result

of signal refl ections at the discontinuities. Finally, signal integrity will also be infl u-

enced by soft errors that are caused by a collision ...
