analog-design-circuit

analog-chip-design-agents

Claude Code marketplace plugin — full analog / mixed-signal + RF chip design pipeline. 16 plugins · 14 design domains + infrastructure + meta pipeline orchestrator · open-source and proprietary EDA tool coverage.

🚧 Status: Phase 1 (core analog spine) implemented. The marketplace registry, per-plugin manifests, CI, and the shared design_state.json schema are in place. The core spine — analog-design-circuit, analog-design-simulation, analog-design-infrastructure, and analog-design-meta — is now fully implemented (detailed stage rules, memory wiring, fix_request loop, infrastructure tooling). The remaining 12 domains ship skeleton SKILL/orchestrators (stage sequence, tool lists, QoR metrics) and are filled in across phases 2–6. See PLAN.md for the roadmap and phase order; the Phase column below marks each domain's target phase (1 = implemented).

This marketplace mirrors the architecture of digital-chip-design-agents, re-targeted to the analog/mixed-signal + RF flow.

Install (preview)

Domains are skeletons until their phase lands; installing now gives you the structure and planned scope, not yet the full flow logic.

/plugin marketplace add github:chuanseng-ng/analog-chip-design-agents
/plugin install analog-design-circuit@analog-chip-design-agents
/plugin install analog-design-simulation@analog-chip-design-agents

A one-step install.sh / install.ps1 and multi-IDE export (Copilot/Gemini/ OpenCode/Codex), matching the reference repo, arrive in Phase 6.

How It Works

Each plugin installs two things, exactly as in the reference repo:

1. A Skill (plugins/<domain>/skills/<skill>/SKILL.md) — domain knowledge Claude reads before executing: stage-by-stage rules, QoR metrics, supported open-source and proprietary tools, and output requirements.

2. An Orchestrator Agent (plugins/<domain>/agents/<domain>-orchestrator.md) — a subagent that sequences stages, enforces pass/fail criteria, applies loop-back rules when a stage fails, and escalates when human input is needed.

The 14 design domains map to the end-to-end analog/mixed-signal + RF pipeline diagrammed in PLAN.md §3. Cross-domain feedback (e.g. a failed Monte-Carlo run looping back to circuit design) is driven by the meta pipeline orchestrator through a shared design_state.json (schema).
