Abstract

Due to technology scaling and increasing clockfrequency, problems due to noise effects lead to anincrease in design/debugging efforts and a decrease incircuit performance. This paper shows how crosstalkcoupling between lines can affect the propagation delayof signals in integrated circuits. A model is presented toevaluate the effect of parasitic coupling crosstalk.Conditions for the creation of the worst-case couplingand propagation of a delayed signal are presented. A testpattern generation algorithm utilizing the aboveconditions is presented and applied to several examplecircuits.
