This article showcases a truly mind-blowing application of Large Language Models (LLMs) in hardware engineering. By simply feeding 2,000 lines of comment-free Verilog code to Gemini, the author witnessed the AI accurately deduce the device's highly specialized purpose—mass spectrometry. This breakthrough demonstrates how AI can effortlessly rescue engineers from daunting, undocumented legacy code and instantly generate comprehensive design specifications!
Key Takeaways
- •Gemini successfully reverse-engineered a massive 14,000-line, 47-module FPGA design with zero comments or documentation.
- •Without any hints, the AI correctly guessed the hardware's specialized application (mass spectrometry) purely from signal naming conventions.
- •The AI mapped out the complex hierarchical structure and control flows, instantly generating a full set of missing design specifications.
