Sky130A open PDK workflow for ngspice-based analog simulation.

  • An agent needs to install
  • SKILL.md covers Quick Start, Model Entry, Included Smoke Examples and Sky130 SCS To ngspice Sky130, plus 1 more section
  • Runs Python scripts from its folder; calls python3
  • Locate Sky130A via Volare/openpdks

What it does

Sky130 Pdk is an agent skill from Arcadia-1/gmoverid-skill. Sky130A open PDK workflow for ngspice-based analog simulation. Use when an agent needs to install or locate Sky130A via Volare/openpdks, run process-corner PVT simulations, run process Monte Carlo or mismatch-aware smoke tests, instantiate sky130fdpr devices, or validate Sky130A examples such as MOS Id-Vgs, ring oscillators, and five-transistor OTAs.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 27 other files, including reference files and assets (for example `assets/run_sky130_five_transistor_ota_pvt_mc.py`, `assets/run_sky130_mos_iv_pvt_mc.py` and `assets/run_sky130_ringosc_pvt_mc.py`).

It sits in Testing & QA, covering QA and bug reports. The repository describes itself as: Agent skill for simulating gmoverid characteristics and gmoverid-based design.

When your agent uses it

  • An agent needs to install
  • Locate Sky130A via Volare/openpdks
  • Run process-corner PVT simulations
  • Run process Monte Carlo

Example prompts

  • “/sky130-pdk”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 8feb841. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sky130 Pdk loads about 1.1k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 326 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 326 words (~1,109 tokens).

“Use this skill for Sky130A ngspice work with the open-source SkyWater/open_pdks PDK. It covers PDK installation, model-path discovery, process corners, process Monte Carlo, and small smoke examples.”
