`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。
`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。
`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）。
`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。
`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。
