提出了一种计算具有任意电源电压波动的单端缓冲器的阶跃脉冲响应的概率密度函数（PDF）的分析方法。为了验证该理论，设计、制造了具有噪声干扰缓冲器和受干扰缓冲器的硅 IC，并将其组装在印刷电路板 (PCB) 中。 IC 和 PCB 的整体配电网络 (PDN) 通过阻抗测量进行建模。通过与 HSPICE 和实验结果的比较，计算并验证了受电源电压波动影响的受害者缓冲器的阶跃脉冲响应的 PDF。由于电源电压波动而获得的 PDF 可以与统计链路模拟方法相结合，以快速估计误码率 (BER)。
An analytical methodology to calculate the probability density functions (PDFs) for the step pulse response of a single-ended buffer with arbitrary power-supply voltage fluctuations is proposed. To validate the theory, a silicon IC with noise-aggressing buffers and a victim buffer was designed, fabricated, and assembled in a printed circuit board (PCB). The overall power distribution network (PDN) of the IC and PCB was modeled from impedance measurements. The PDFs of the step pulse response of the victim buffer with power-supply voltage fluctuations were calculated and validated by comparisons with HSPICE and experimental results. The obtained PDFs due to power-supply voltage fluctuations could be combined with the statistical link simulation methods for quick estimation of bit error rate (BER).
