DRCY: Agentic Hardware Design Reviews
This addresses a critical issue for hardware designers by automating semantic verification, though it is incremental as it builds on existing EDA tools with LLM-based enhancements.
The paper tackles the problem of hardware design errors that cause costly post-fabrication respins by introducing DRCY, a multi-agent LLM system that automates schematic connection reviews by fetching datasheets and performing pin-by-pin analysis, deployed in production on AllSpice Hub and used by major companies.
Hardware design errors discovered after fabrication require costly physical respins that can delay products by months. Existing electronic design automation (EDA) tools enforce structural connectivity rules. However, they cannot verify that connections are \emph{semantically} correct with respect to component datasheets. For example, that a symbol's pinout matches the manufacturer's specification, or that a voltage regulator's feedback resistors produce the intended output. We present DRCY, the first production-ready multi-agent LLM system that automates first-pass schematic connection review by autonomously fetching component datasheets, performing pin-by-pin analysis against extracted specifications, and posting findings as inline comments on design reviews. DRCY is deployed in production on AllSpice Hub, a collaborative hardware design platform, where it runs as a CI/CD action triggered on design review submissions. DRCY is used regularly by major hardware companies for use-cases ranging from multi-agent vehicle design to space exploration. We describe DRCY's five-agent pipeline architecture, its agentic datasheet retrieval system with self-evaluation, and its multi-run consensus mechanism for improving reliability on safety-critical analyses
