The effect of the transition time of load currents was taken into account, and a more realistic worst-case noise prediction was obtained. In addition, a dynamic programming algorithm is introduced for the time-domain impulse response of the power distribution system, and a modified Knuth-Yao quadrangle inequality speedup method is developed which reduces the time complexity of the algorithm from O(n2m) to O(mnlogn). %K 动态规划 最差噪声 变化率 电源分布网络 时域分析< %K /br> %K dynamic programming worst-case noise transition time power delivery network time-domain analysis %U http://journal.nudt.edu.cn/gfkjdxxb/ch/reader/view_abstract.aspx?file_no=201602014&flag=1
