analog-architecture

analog-architecture is a skill for Claude Code from hdl-tools/analog-chip-design-agents. It costs 76 tokens per session (3,065 once invoked), scanned A, original, MIT.

A planning workflow that turns a top-level analog or mixed-signal system specification into requirements for each circuit block. It budgets noise, linearity, and power and checks whether the design is feasible.

In plain words
What is it for?
Use it to plan receiver and sensor front ends, data converters, phase-locked loops, clock systems, and power-management chips.
Why use it?
It exposes unrealistic requirements and trade-offs before detailed circuit design begins.

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

analog-architecture 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 2mo 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: Analog Architecture

Invocation

  • If invoked by a user presenting an architecture/budgeting task: immediately spawn the analog-chip-design-agents:analog-architecture-orchestrator agent and pass the full user request and any available context. Do not execute stages directly.
  • If invoked by the analog-architecture-orchestrator mid-flow: 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/architecture/knowledge.md — known budgeting recipes, cascade pitfalls, process/topology trade-offs. Incorporate its guidance into every allocation decision.
  2. memory/architecture/run_state.md — current run identity (run_id, design_name, pdk, last_stage) for resume-after-interruption.

Purpose

Translate a top-level system specification into a closed, feasible per-block specification contract. Architecture is the upstream domain: it budgets noise, linearity, power, and area across the signal chain and hands circuit-design a per-block spec table. Five stages with explicit QoR gates and loop-back criteria enforced by the analog-architecture orchestrator. Architecture is intentionally technology-light — it runs from system specs and does not require a pdk.

Supported EDA Tools

Open-Source

  • Python budgeting (python, NumPy / scikit-rf) — cascaded noise/linearity/power math
  • Jupyter (jupyter) — interactive budget exploration and documentation
  • ngspice (ngspice) / Xyce (Xyce) — behavioral-source sanity checks of allocations

Proprietary (detect-only — never installed)

  • Cadence ADE Assembler / Spectre (spectre) — system/behavioral verification
  • Keysight SystemVue — system-level signal-chain modeling
  • MATLAB / Simulink (matlab) — system models and budget analysis

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.

analog-architecture is a skill published in the GitHub repository hdl-tools/analog-chip-design-agents (25 stars, last pushed 5mo ago), licensed MIT. It adds 76 tokens to every session and 3,065 once invoked, about $0.0003 per session on Opus 5.5. 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.
