A Comprehensive Evaluation of Crosstalk Noise in Partially Coupled Nano Scale VLSI Interconnects

Interconnects' crosstalk plays a key role in ultra dense nano scale VLSI circuits because of its multi dimensional impact on overall reliability and performance of ICs. Many researches have been conducted to evaluate the crosstalk and derive expressions for the analysis. This paper presents evaluation of the crosstalk in a different structure utilizing both rigorous simulations and analytical formulations. In the partially coupled interconnects structure, considered in this work, the crosstalk effects are investigated while the position and coupled length of the interconnect wires (aggressor and victim) are varied. We show that in all the cases where the victim line stay behind the aggressor line, the crosstalk is larger than the opposite cases for which the victim line is placed ahead of the aggressor line. Consequently, for a structure of relevant parameters, the crosstalk can be reduced up to 92% compared to the interconnect system of the opposite structure
