摘要

提出了一种新的异步电路交换集成电路互连信号完整性验证方法。斜坡输入用延迟阶跃输入建模。然后利用基于行波的波形近似技术，准确有效地确定了异步输入信号切换引起的信号暂态变化。结果表明，采用90nm技术，具有异步开关输入的多耦合线的信号时序和串扰与SPICE仿真非常吻合，但其计算时间比采用基于通用分段的RLC电路模型的SPICE仿真快几千倍

Efficient signal integrity verification method of multi-coupled RLC interconnect lines with asynchronous circuit switching

A new signal integrity verification method of integrated circuit interconnects with asynchronous circuit switching is presented. A ramp input is modeled with delayed step inputs. Then signal transient variations due to asynchronous input signal switching are accurately as well as efficiently determined by using traveling-wave-based waveform approximation (TWA) technique. It is shown that using 90nm technology, the signal timing and crosstalk of multi-coupled lines with asynchronous switching inputs have an excellent agreement with SPICE simulation but its computation time is several thousand times faster than that of SPICE simulation using generic segment-based RLC circuit model
