Tools (16)

analyze_kicad_pcbread-onlyParse and analyze a KiCad `.kicad_pcb` board locally (from `pcb_text` or `project_path`). Extracts copper layer stackup, board outline dimensions (mm), footprint count, SMD vs THT pad counts, fine-pitch (<=0.50mm) pad count, net count, routed trace/arc segment statistics, and via count.
analyze_specctra_dsnread-onlyParse and analyze a Specctra `.dsn` PCB autorouter file locally (from `dsn_text` or `project_path`). Extracts units, resolution, signal/power copper layers, board boundary dimensions, component count, netlist summary, and design rule clearances/widths.
audit_pcb_dfm_rulesread-onlyRun a local Design-for-Manufacturing (DFM) rule check on a `.kicad_pcb` or `.dsn` file against standard 2-layer or 4-layer fabrication limits (minimum trace width, clearance, via hole diameter, and annular ring width).
audit_pre_route_rf_and_fab_stackupread-onlyRun the 4-Stage Pre-Route Vendor Stackup, 50-Ohm Microstrip vs. Coplanar Waveguide (CPWG) Impedance, 3*H1 Coplanar Ground-Pour Encroachment, Inner Reference-Plane Return Corridor, and Via-in-Paste (VIPPO) manufacturing gate on a `.kicad_pcb` before routing begins.
calculate_pcb_trace_impedanceread-onlyLocal PCB transmission-line impedance & IPC-2152 trace current calculator. Computes single-ended microstrip/stripline Z0 (Ohms), edge-coupled differential Zdiff (Ohms), propagation delay (ps/mm), and recommended trace width for a target impedance or DC current (Amps).
calligraphy_compile_boardCompile a PCB through Calligraphy EDA (3D HDI synthesis + Snowman teardrop pad fillets + Zero-VIPPO DFM surgery + 3D nodal G*V=I physics) and return 0-DRC telemetry, preview crops, a single clickable Stripe Checkout URL, and watch-only per-job USDT/USDC stablecoin payment instructions. Mode A (Zero-File Demo): Pass `sample_id='2l_rp2040'` (or `'2l_stickhub'`, `'4l_carrier'`). Mode B (User's Local Board over Remote HTTP): Read the user's local `.kicad_pcb`, `.dsn`, `.ato`, or `.tsx` file and pass its contents in `pcb_text` + `filename` (or `upload_b64` for `.PcbDoc`/`.zip`).
calligraphy_create_coinbase_checkoutCreate a 1-Click Coinbase Pay / Coinbase Onchain Payment Protocol checkout session (and x402 AI-agent payment URL) settling in USDC on Base (chain_id=8453) with automatic DEX token conversion and zero gas-dust sweeping.
calligraphy_download_fab_bundleread-onlyDownload the unlocked routed .kicad_pcb and turnkey JLCPCB/PCBWay .zip bundle (Gerbers, Excellon drills, IPC-D-356, BOM, CPL, and 3D HTML5 viewer) once paid via Stripe Checkout, autonomous USDT/USDC stablecoin verification, or active 30-day board license.
calligraphy_get_job_statusread-onlyQuery the compilation and payment status of a Calligraphy EDA job (`job_id`). When `status` is `COMPLETED_AWAITING_PAYMENT`, returns `stablecoin_payment_instructions` with the job's unique watch-only `deposit_address` (`0x...`) for autonomous USDT/USDC checkout.
calligraphy_list_gallery_boardsread-onlyList the 55 / 55 conquered open-source PCB benchmark boards (20/20 PCBench Tier T Frontier + 13/13 Tier D Torture + 22/22 Multi-ECAD — 100.0% routed, 0 native KiCad 9 copper DRC violations) and available 1-click sample demo IDs ('2l_rp2040', '2l_stickhub', '4l_carrier').
calligraphy_lookup_b2b_invoiceread-onlyLook up a Calligraphy EDA job and generate a B2B Tax Invoice & Chain-of-Custody Certificate with custom PO number and company name.
calligraphy_preflight_auditread-onlyInspect a .kicad_pcb file or .zip project bundle (including atopile/tscircuit/Altium/Allegro builds), verify outline/pad readiness, and return a deterministic 3-Lever NRE-anchored price quote ($149 vibe_micro for <=150 pads up to $1,495+ route_3d). Mode A (Zero-File Demo): Pass `sample_id='2l_rp2040'` (or `'2l_stickhub'`, `'4l_carrier'`). Mode B (User's Local Board over Remote HTTP): Read the user's local `.kicad_pcb`, `.dsn`, `.ato`, or `.tsx` file and pass its contents in `pcb_text` + `filename` (or `upload_b64` for `.PcbDoc`/`.zip`).
calligraphy_purge_job_vaultdestructiveImmediately shred all enclave CAD and synthesis artifacts for job_id and return a cryptographically signed CertificateOfDestruction (zero_retention_verified=True).
calligraphy_request_ip_whitelistSubmit a Support Whitelist Request for an engineering team, corporate NAT IP, or PCB layout agency that needs higher daily compilation write limits (e.g. 25–100 compiles/day).
calligraphy_route_pcbAlias for calligraphy_compile_board: synthesize and route a PCB through Calligraphy EDA (0 opens, 0 DRC) and return Stripe, Coinbase Pay (x402), and watch-only USDT/USDC payment instructions. Mode A (Zero-File Demo): Pass `sample_id='2l_rp2040'` (or `'2l_stickhub'`, `'4l_carrier'`). Mode B (User's Local Board over Remote HTTP): Read the user's local `.kicad_pcb`, `.dsn`, `.ato`, or `.tsx` file and pass its contents in `pcb_text` + `filename` (or `upload_b64` for `.PcbDoc`/`.zip`).
calligraphy_verify_stablecoin_paymentSubmit an on-chain `USDT` or `USDC` transaction hash (`tx_hash`) sent to the job's unique watch-only `deposit_address` on `base`, `arbitrum`, `polygon`, or `ethereum` to receive a private HMAC-SHA256 payment receipt (`receipt_hmac_sha256`) and immediately unlock `calligraphy_download_fab_bundle` with zero human browser intervention.
