OmniLayout
1,681 industrial schematic-coupled layouts testing constraint-aware component placement (legality, routability, electrical-function preservation) with an agentic tool-use track.
What it does and how it connects
OmniLayout is a benchmark for evaluating large language models on PCB layout placement reasoning under geometric, routing, and connectivity constraints. It contains 1,681 industrial-grade schematic-coupled PCB layouts with expert-designed reference placements, covering board outlines from 2 to 8 layers and areas from about 31.5 to 22,459 square millimetres.
The benchmark has four tasks: geometric reasoning for IC physical placement with 77,240 placement instances constrained within board boundaries; routability-aware placement reasoning that generates physically valid component placements; electrical functionality, which preserves schematic-specified connectivity and electronic functional correctness; and tool-augmented agentic reasoning for invoking external tools to accomplish the first three tasks.
The layouts are drawn from real-world schematic designs collected from open-source hardware platforms including SparkFun, Arduino, Adafruit, Seeed, and ProtoCentral, implemented in Autodesk EAGLE. The paper reports substantial limitations in current models, including weak geometric reasoning, poor routability optimization, and inconsistent preservation of electrical functionality.
