# Calligraphy Systems LLC (@CalligraphyEDA) — Autonomous Physical PCB Synthesis & Turnkey Fab Cloud

> Calligraphy EDA transforms unrouted KiCad (.kicad_pcb), Altium (.PcbDoc), Cadence/OrCAD/Allegro (.dsn), IPC-2581 (.xml), atopile (.ato), and tscircuit (.tsx) boards into 100.0% routed, 0-DRC production copper layouts with turnkey JLCPCB/PCBWay manufacturing bundles (.zip).

## Core Engineering Capabilities
- **100.0% Geometric Completion & 0 Native KiCad Copper DRC (`NO_PARTIAL_SALES = True`)**: You never pay for an incomplete or DRC-violating board.
- **Multi-ECAD Native Intake & Round-Trip**: Supports `.kicad_pcb`, `.PcbDoc`, `.dsn`, `.xml` (IPC-2581), `.ato` (atopile), and `.tsx` (tscircuit) with 0.00000 mm coordinate drift.
- **Signal Integrity, DFM & 3D Nodal Physics**: High-Density BGA Escape Allocation, Global Multi-Layer Congestion Balancing, Impedance-Controlled Differential Pair Coupling, 3D Return-Path Continuity & Loop-Inductance Control, IPC-2221 Acid-Trap-Free Routing & Snowman Teardrop Reinforcement, and 3D Resistive Nodal (`G * V = I`) Voltage-Drop Verification.
- **Turnkey Factory Deliverable (`.zip`)**: Includes routed native CAD files, Gerber X2 + Excellon drills, IPC-D-356A netlist verification, JLCPCB/PCBWay BOM & CPL assembly files, and a zero-install 2D/3D HTML5 inspection viewer.

## Pricing Tiers (Pay Only After Inspecting 0-DRC Proof)
