从电源完整性( PI)的角度分析了抑制同步开关噪声( SSN)的有效途径---降低芯片供电电源的输入阻抗。使用目标阻抗法，并对给定最大去耦电容容值种类的条件下，使用频域对数法进行电源地分配网络( PDN)的优化。以XX电子控制器的PCB板为例，使用Ansoft SIwave及Ansoft Designer仿真软件，对复杂高速PCB板PDN进行优化设计，并通过时域观察优化前后SSN的抑制情况。仿真结果表明：通过优化PDN能够有效降低SSN。

From the aspect of Power Integrity ( PI ) , the effective way of suppressing simultaneous switching noise ( SSN) is reduce chip’s input impedance. With the method of target impedance determined by the number of decoupling capacitance which frequency domain logarithmic is used to optimize power delivery network ( PDN ) . Based on XX-electronic-controller PCB,a high-speed complicated PCB’ PDN is analyzed and optimized by Ansoft SIwave and using time-domain observes the inhibition of SSN by Ansoft Designer. The simulation resultes show that the optimization of power distribution network can reduce SSN effectively.
