SPICE Simulation
Auto-generate and run SPICE testbenches for KiCad subcircuits, with a structured pass, warn and fail report.
- What
- Auto-generate and run SPICE testbenches for KiCad subcircuits, with a structured pass, warn and fail report.
- Cost
- Free
- Needs
- an AI agent with file tools (Read, Write, Bash), such as Claude Code or Codex; Python 3 for the helper scripts; a SPICE simulator installed on the machine (ngspice, LTspice or Xyce, auto-detected). Pairing with the kicad skill is recommended, since it detects the subcircuits to simulate.
- Install
- Copy the installer prompt below into your Muse — your agent does the rest.
Curated by Skill Harbor: the simulation skill in the KiCad collection, and a useful inversion of the usual simulation workflow. Instead of asking the user to build simulation sources and configure an analysis, it generates and runs SPICE testbenches automatically for subcircuits detected by the kicad skill's schematic analyzer: resistor-capacitor filters, inductor-capacitor filters, voltage dividers, opamp circuits and crystal oscillators. It validates calculated values, filter frequencies, divider ratios, opamp gains and crystal load capacitance, against actual simulation results, and produces a structured pass, warn and fail report. It supports ngspice, LTspice and Xyce, auto-detected, and it uses parametric data from the distributor skills for behavioral part models. By @aklofas, listed here with credit to its creator. Honest caveats: it works best paired with the kicad skill, which detects the subcircuits to simulate; a SPICE simulator must be installed on the machine, the skill does not install one; and simulation results validate a model of the circuit, not the built board, so real measurements still have the last word. Skill Harbor never reviews the code, review it yourself before use.
Version:
Quick answer
SPICE Simulation is a free Muse skill that generates and runs SPICE testbenches for subcircuits from the kicad skill: filters, voltage dividers, opamp circuits and crystal oscillators. It validates values against simulation and produces a pass, warn and fail report, with ngspice, LTspice and Xyce. With the kicad skill, simulator required, simulation validates a model, not the board.
Install
Copy the install package below, then paste it into MusePrerequisites: an AI agent with file tools (Read, Write, Bash), such as Claude Code or Codex; Python 3 for the helper scripts; a SPICE simulator installed on the machine (ngspice, LTspice or Xyce, auto-detected). Pairing with the kicad skill is recommended, since it detects the subcircuits to simulate. Install "SPICE Simulation" for me. A skill that auto-generates and runs SPICE testbenches for KiCad subcircuits, filters, dividers, opamp circuits and crystal oscillators, and produces a structured pass, warn and fail report. Repository: https://github.com/aklofas/kicad-happy/tree/main/skills/spice 1. Fetch the SKILL.md file (plus its references/ and scripts/ folders) from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). It must never contain hardcoded secrets. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "spice". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. confirm which SPICE simulator is installed). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it is in the prerequisites above. Rules: do not touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.

Questions
How do I install a skill?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the skill up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a skill before installing it.
