OmniRouting: A Semantic-Coupled Multimodal Benchmark for Constraint-Aware Spatial Reasoning in PCB Routing
The OmniRouting benchmark, with 1,681 PCB designs, shows current large multimodal models achieve under 13% clean net routability while humans reach about 94%, exposing major gaps in constraint-aware spatial reasoning.
