Engineer creates CPU from scratch in two weeks, begins work on GPUs
The finished design is heading for TinyTapeout 6
Learning the fundamentals of chip architecture – a strong understanding is a critical foundation Learning the fundamentals of chip fabrication – materials, wafer prep, patterning and packaging Starting electronic design automation by making a CMOS transistor, layer-by-layer Creating my first full circuit in Verilog – “my first experience with programming hardware using software.” Implementing simulation & formal verification for my circuit Designing my first full chip layout – designing and optimizing using OpenLane, which is an open-source EDA tool Despite this hurdle, Majmudar says the big GPU-makers’ secrecy has made this part of the project “way more fun for me.” Interestingly, Anthropic’s Claude Opus AI tools have been useful during this GPU designing stage. “I've been proposing my ideas for how each unit must work to Claude, and then somehow it will guide me toward the right implementation approaches which I can then go and confirm with open-source repos,” explained the engineer.
