New OmniLayout benchmark reveals LLM limitations in PCB design reasoning

Researchers have introduced OmniLayout, a new benchmark designed to test the geometric reasoning capabilities of large language models (LLMs) in the context of printed-circuit-board (PCB) layout design. The benchmark comprises 1,681 industrial-grade PCB layouts and includes tasks focused on geometric placement, routability, electrical functionality, and tool-augmented reasoning. Initial results indicate that current LLMs struggle with these complex spatial and functional constraints, exhibiting weaknesses in geometric reasoning, routability optimization, and maintaining electrical connectivity.
