LLM framework generates verifiable PCB schematics without unit tests

Researchers have developed PCBSchemaGen, a novel framework designed to enable large language models (LLMs) to generate verifiable code for printed circuit board (PCB) schematic designs. Unlike typical code synthesis benchmarks that rely on unit tests, PCBSchemaGen uses a domain-specific schema derived from integrated circuit datasheets and a continuous-reward verifier to ensure correctness. This approach allows even an open-weight 31B model like Gemma-4-31B to achieve an 81.3% success rate on PCBBench tasks, demonstrating its effectiveness in domains lacking traditional testing oracles.
