With the reducing distances between wires in deep submicrometer technologies, coupling capacitances are becoming significant as their magnitude becomes comparable to the area capacitance and fringing capacitance of a wire. This causes an increasing susceptability to failure due to inadvertent noise and leads to a requirement for accurate noise estimation. An incorrect estimation of the noise could lead either to circuit malfunction in case of underestimation or to wasted design resources due to overestimation. This paper presents a new time-efficient method for the precise estimation of crosstalk noise. While existing fast noise estimation metrics may overestimate the coupling noise by several orders of magnitude, the proposed metric computes the coupling noise with a good accuracy as compared to SPICE.
