AMD-Link: Autonomous PCB Routing for Ryzen

AMD-Link is an autonomous hardware design system that brings cognitive hardware awareness to PCB layout, specifically targeting the routing bottleneck around the AMD Ryzen Embedded V3000 Series. The V3000 is a powerful Zen 3 SoC offering up to 8 cores, 20 lanes of PCIe Gen4, dual 10Gb Ethernet, and a flexible 10W–54W TDP envelope — but its 484-pin BGA package puts manual board layout out of reach for most builders. Limited routing channels, multilayer escape strategies, and the strict length-matching and impedance demands of buses like DDR5 mean that even seasoned engineers can spend hours fan-out routing a single device, with constant risk of DRC violations and human error. AMD-Link replaces that grind with an AI engine that ingests a KiCad PCB, reasons about the pin grid, and generates compliant routes in seconds. In our demo it navigates the dense 484-pin V3000 grid to a breakout header, avoids obstacles, and maintains parallel bus alignment automatically — collapsing a 30-minute manual task into roughly 5 seconds, and a full board fan-out from 120+ minutes (manual) or 45 minutes (traditional autorouter) down to 2 minutes. That's up to a 60x improvement in routing efficiency. The system is wrapped in a Mission Control UI built on Streamlit with custom CSS, providing real-time compliance gauges, live PCB layout previews, audit logs of every AI routing decision, and instant signal-name cross-referencing. We separate Objective Health (ground-truth KiCad DRC/ERC rules) from Subjective Confidence (the AI's self-assessment), so low-confidence edge cases get flagged for human review while routine patterns are committed automatically. Our roadmap extends from BGA fan-out (current) through DDR5 length matching, multi-agent thermal/SI co-optimization, and ultimately a schematic-to-silicon autonomous workflow.
