Changes things 5Claude Code: ask
  • 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）。No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

  • 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。No findings

  • 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）。No findings

  • 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。No findings

Only reads 1Claude Code: allow
  • 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。No findings

    Why it is in this group

    • The name "diff_skew" says "diff": a word for reading.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
