impedance用 2D 電場數值解算微帶線或帶狀線的差動阻抗(Zdiff、Zcomm、奇/偶模)或單端阻抗(Z0),含銅厚。回傳附適用範圍。
crosstalk兩條耦合線的串音:偶/奇模阻抗用 2D 電場數值解,再算近端串音係數 kb、飽和比例、遠端串音係數。只回傳解析式的部分(不含工具頁的 ngspice 時域波形)。
diff_skew兩條線的長度差換成時間差(ps),對照介面的上限:USB3/PCIe 用業界經驗值 5 mil(非規範原文,出處見適用範圍);DisplayPort/HDMI 沒有預設,請用 lim 填晶片廠或規範給的值。
xtal_load_cap外掛電容 C1、C2 與雜散電容算出實際負載電容 CL、頻率偏移 ppm、振盪增益餘裕、驅動功率,並給出剛好對上規格 CL 的電容值。
output_voltage_tolerance回授電阻分壓的輸出電壓:最壞情況(每項取上下限的所有組合)、RSS 統計;可選蒙地卡羅超規比例。
inrush_current負載開關控速上升時的充電電流、峰值電流、能量與脈衝 I²t(mode=slew),或電容直接接電源時的串聯 R-L-C 步階電流(mode=direct)。
