physical-verification

physical-verification is a skill for Claude Code from hdl-tools/analog-chip-design-agents. It costs 77 tokens per session (2,045 once invoked), scanned A, original, MIT.

Guidance for checking an analog chip layout against manufacturing rules and the original circuit description.

In plain words
What is it for?
Use it to verify or re-verify a custom GDS layout. DRC finds manufacturing-rule violations; LVS checks that the layout represents the intended circuit.
Why use it?
It structures DRC, LVS, antenna, electrical-rule, and density checks and explains how to respond when one fails.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

physical-verification scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill: Physical Verification

Invocation

  • If invoked by a user presenting a physical-verification task: immediately spawn the analog-chip-design-agents:physical-verification-orchestrator agent and pass the full user request and any available context. Do not execute stages directly.
  • If invoked by the physical-verification-orchestrator mid-flow (including re-validation): do not spawn a new agent. Treat this file as read-only — return the requested stage rules, sign-off criteria, or loop-back guidance.

Spawning the orchestrator from within an active orchestrator run causes recursive delegation and must never happen.

Pre-run Context

Before executing or advising on any stage, read the following if they exist:

  1. memory/physical-verification/knowledge.md — known DRC waiver patterns, LVS debug recipes, antenna fixes, PDK deck quirks. Incorporate its guidance into every check.
  2. memory/physical-verification/run_state.md — current run identity for resume-after-interruption.

Purpose

Verify a custom layout against the foundry rule deck and the source netlist: DRC, LVS, antenna/ERC, and density/DFM, ending in a physically-clean sign-off. Five stages with explicit QoR gates. On a DRC or LVS failure the layout cannot self-resolve, this domain opens a fix_request routed by the pipeline-orchestrator to custom-layout.


Supported EDA Tools

Open-Source

  • Magic (magic) — DRC and device extraction for LVS
  • Netgen (netgen) — LVS (layout-vs-schematic netlist comparison)
  • KLayout (klayout) — DRC / LVS decks (sky130/gf180mcu/ihp-sg13g2; predictive freepdk45/asap7, the latter with multi-patterning/coloring rules), antenna checks

Proprietary (detect-only — never installed)

  • Siemens Calibre nmDRC / nmLVS (calibre) — industry DRC/LVS sign-off
  • Synopsys IC Validator (ICV) (icv)
  • Cadence Pegasus / Assura (pegasus)
  • Silvaco Guardian — DRC/LVS/ERC

Stage: drc

Domain Rules

  1. Run the foundry DRC deck (Magic + KLayout) for the target constraints.pdk; resolve every violation to 0 unwaived.
  2. Fix spacing/width/enclosure now; defer density/antenna-adjacent rules to their dedicated stages.
  3. Document any intentional waiver with a foundry-acceptable justification; an undocumented waiver is a failure.
  4. A DRC failure the layout cannot self-resolve opens a fix_request to custom-layout (failure_class: drc_lvs).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

physical-verification is a skill published in the GitHub repository hdl-tools/analog-chip-design-agents (22 stars, last pushed 3mo ago), licensed MIT. It adds 77 tokens to every session and 2,045 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
