rat-auto-design

Execute the full RTL design pipeline from specification to verified silicon. In team mode (default), the skill directly sequences phases using phase-specific team skills for parallel execution. In sequential mode (--no-team), delegates to autopilot-orchestrator.

<Use_When>

• Starting a complete RTL design from a specification document
• User says "design a chip", "full pipeline", "RTL design", "autopilot"
• Need end-to-end flow: Research → Architecture → μArch → RTL → Verify → Design Note </Use_When>

<Do_Not_Use_When>

• Only need a specific phase (use the phase-specific skill instead)
• Only need design space exploration (use rat-dse)
• Only need design documents without RTL (use rat-p1p3-spec-uarch) </Do_Not_Use_When>

Prerequisites

None — this is the full pipeline entry point. Setup is handled automatically.

    Task(subagent_type="rtl-agent-team:p6-review-orchestrator",
         prompt="Execute Phase 6 design review. Context: Phase 5 PASS.")

    # Mark completed (stop-gate.sh reads top-level "status" to allow exit)
    # Write completed status BEFORE cleanup so stop hook sees it
    # Portable in-place JSON edit — avoids GNU/BSD sed -i differences (macOS BSD sed requires `-i ''`).
    Bash("python3 -c 'import json, pathlib; p = pathlib.Path(\".rat/state/rat-auto-design-state.json\"); d = json.loads(p.read_text()); d[\"status\"] = \"completed\"; p.write_text(json.dumps(d, indent=2))'")
    # Cleanup state
    Bash("rm -f .rat/state/rat-auto-design-state.json")

else:
    # ═══ SEQUENTIAL MODE: Delegate to autopilot-orchestrator ═══
    Task(subagent_type="rtl-agent-team:autopilot-orchestrator",
         prompt="Execute full RTL autopilot pipeline. --no-team. User input: $ARGUMENTS")

Team mode uses native teams within each phase for parallel execution (Orchestrator as Teammate pattern). Each phase team skill handles its own TeamCreate/TeamDelete lifecycle with a coordinator teammate + 3-5 workers. Sequential mode delegates everything to the autopilot-orchestrator.

Output

• Design artifacts: docs/phase-1-research/ through docs/phase-5-verify/
• Phase 6 design note and review verdicts: reviews/phase-6-review/ (Phase 6 is the design review + documentation phase; its outputs live under reviews/, not docs/)
• rtl/*/*.sv — lint-clean, unit-tested RTL modules
• sim/ — testbenches, regression results, and coverage data
• reviews/ — per-phase review reports with final compliance verdict
