From RTL to Prompt Coding: Empowering the Next Generation of Chip Designers through LLMs

2026-01-20

AI Summary

This work proposes the first LLM-driven educational platform that spans the entire chip design flow—from front-end RTL to back-end tapeout—addressing the high barrier to entry and the steep learning curve faced by beginners. The platform integrates a conversational agent with the Tiny Tapeout ecosystem, enabling an end-to-end, natural language–guided chip design workflow directly within a web browser. In experimental validation, 18 high school students with no prior experience successfully designed eight distinct functional 130nm VGA chips within 90 minutes, all of which achieved tapeout-ready status. These results demonstrate that the approach not only substantially lowers the accessibility threshold for chip design but also exhibits strong pedagogical efficacy and engineering feasibility.

Abstract

This paper presents an LLM-based learning platform for chip design education, aiming to make chip design accessible to beginners without overwhelming them with technical complexity. It represents the first educational platform that assists learners holistically across both frontend and backend design. The proposed approach integrates an LLM-based chat agent into a browser-based workflow built upon the Tiny Tapeout ecosystem. The workflow guides users from an initial design idea through RTL code generation to a tapeout-ready chip. To evaluate the concept, a case study was conducted with 18 high-school students. Within a 90-minute session they developed eight functional VGA chip designs in a 130 nm technology. Despite having no prior experience in chip design, all groups successfully implemented tapeout-ready projects. The results demonstrate the feasibility and educational impact of LLM-assisted chip design, highlighting its potential to attract and inspire early learners and significantly broaden the target audience for the field.
