随着半导体技术的不断进步，互连串扰对超大规模集成电路的性能产生了很大的影响。迄今为止，关于VLSI电路互连的研究大多集中在电压模式信令（VMS）方案上，而对电流模式信令（CMS）方案的分析很少。首先，本文提出了适用于CMS和VMS方案的双线耦合互连等效电路模型。等效电路模型考虑了电容耦合和互感耦合。其次，根据解耦技术和ABCD参数矩阵法分别在局部、中间和全局层面研究了CMS和VMS方案的输出噪声。实验结果表明，在相同情况下，CMS互连比VMS互连具有更小的噪声峰值、噪声宽度和噪声幅值，特别适用于VLSI电路的全局互连通信。结果表明，ABCD参数矩阵法得到的结果与先进设计系统的仿真结果吻合较好。
With the continuous advancement of semiconductor technology, the interconnects crosstalk has had a great influence on the performances of VLSI circuits. To date, most of the research about the interconnects of VLSI circuits focus on the voltage-mode signaling (VMS) scheme while the current-mode signaling (CMS) scheme is rarely analyzed. First of all, an equivalent circuit model of two-line coupled interconnects is presented in this paper, which is applicable to both the CMS and VMS schemes. The coupling capacitive and mutual inductive are taken into account in the equivalent circuit model. Secondly, the output noise of CMS and VMS schemes are investigated in the paper according to the decoupling technique and ABCD parameter matrix approach at local level, intermediate level and global level, respectively. Moreover, the experimental results show that the CMS interconnects have lesser noise peak, noise width and noise amplitude than the VMS interconnects in the same cases, and the CMS scheme is especially suitable for the global interconnects communication of VLSI circuits. It is found that the results obtained by ABCD parameter matrix approach are in good accordance with the simulation results of the advanced design system.
