What it can do

Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.

  • 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)。

Common questions

Is Circuit Sim Lab (電路模擬實驗室) safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 36 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
