PCBRouteAgent

PCBRouteAgent is a multimodal agent for printed circuit board routing. A Global Routing Planner uses board images and structured electrical and geometric data to set connection topology, routing order and layer transitions, while a Detailed Routing Executor carries these out through KiCad's native router with bounded local recovery. On 247 synthetic and real-world boards from PCBWorld-Bench, it reports clean-pass rates of 100%, 94.9%, 100% and 40% on the D2, D3-A, D3-B and D3-C splits, and beats the best baseline by 13.9, 36 and 10 percentage points on the three real-world subsets.
