AI-Driven PCB Design Startup Diode Computers Secures $11.4M in Series A Funding

Diode Computers, a startup leveraging artificial intelligence to streamline printed circuit board (PCB) design, has raised $11.4 million in a Series A funding round led by Andreessen Horowitz, with participation from Y Combinator. The company aims to serve robotics, medical device, and aerospace industries by automating the traditionally slow and costly PCB design and manufacturing process.

PCBs, the copper-based frameworks powering devices like smartphones and drones, often require weeks to months for design due to manual processes and legacy electronic design automation (EDA) tools. Diode’s approach uses AI to generate custom PCB designs from code, reducing design time to days. Its open-source toolchain, built in Rust, compiles schematics in milliseconds, while a Pythonic code base allows large language models to detect bugs and cross-reference datasheets. Designs are exportable to industry-standard tools like KiCad, Altium, and Cadence, and each is reviewed by experienced electrical engineers to ensure safety, compliance, and manufacturability.

Diode’s platform includes a specification generator that converts requirements into manufacturable designs within hours, a bill of materials (BOM) compiler providing real-time cost and availability data, and an instant quoting system for manufacturing and assembly costs. The routing and layout engine optim...
