DRCY: Agentic Hardware Design Reviews

TL;DR

DRCY is a multi-agent LLM system that automates semantic verification of hardware schematics by analyzing datasheets and connections, reducing costly post-fabrication errors in hardware design.

Contribution

It introduces the first production-ready multi-agent LLM system for automated schematic connection review with datasheet analysis and inline commenting.

Findings

Deployed on AllSpice Hub for real-world hardware design review

Used by major companies for vehicle and space hardware projects

Enhances early detection of design errors before fabrication

Abstract

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
