In March of this year a post made it to the front page of Hacker News regarding Tiny Tapeout(<a href="https://news.ycombinator.com/item?id=35376645">https://news.ycombinator.com/item?id=35376645</a>). Here, they had made a process where you could submit custom, miniature silicon designs to a subset of a silicon shuttle for just $100.<p>I was already using LLMs to write Verilog for my research, so I was inspired to start another thread exploring if they were yet reliable enough to design whole chips. They were, and I right now have christmas tree LEDs blinking and controlled from a micro designed by ChatGPT and taped out by Efabless!<p>My blog post explores the whole journey as it happened, and links to the various repositories, paper, and webinars along the way.
