基于65nm CMOS工艺,综合考虑电容耦合与电感耦合效应,提出了一种互连线耦合串扰分布式RLC解析模型.采用函数逼近理论与降阶技术,在斜阶跃输入信号下,提出了被干扰线远端的串扰数值表达式.基于65nm CMOS工艺,对不同的互连耦合尺寸下的分布式RLC串扰解析模型和Hspice仿真结果进行了比较,误差绝对值都在2.50%内,能应用于纳米级SOC的计算机辅助设计.
Based on the 65nm CMOS process,a novel parallel RLC coupling interconnect analytical model is presented synthetically considering parasitical capacitive and parasitical inductive effects. Applying function approximation and model order-reduction to the model, we derive a closed-form and time-domain waveform for the far-end crosstalk of a victim line under ramp input transition. For various interconnect coupling sizes, the proposed RLC coupling analytical model enables the estimation of the crosstalk voltage within 2.50% error compared with Hspice simulation in a 65nm CMOS process. This model can be used in computer-aided-design of nanometer SOCs.
