AI agent designs a complete RISC-V CPU from a 219-word spec sheet in just 12 hours — comparably simple design required 'many tens of billions of tokens'
- Verkor.io's Design Conductor autonomously produced VerCore from a 219-word spec in 12 hours, a first in CPU design from spec to layout.
- VerCore is a five-stage, in-order CPU core that ran at 1.48 GHz in simulation on the ASAP7 7nm design kit.
- The design used a Booth-Wallace multiplier clocked at 2.57 GHz and a one-cycle branch penalty design chosen after testing alternatives.
- Verkor notes that traditional leading-edge chips cost hundreds of millions and take 18–36 months with large teams, while VerCore is far simpler.
- Researchers acknowledge limitations of the underlying language models and that some timing issues require simpler explanations.
- Five to ten human experts are expected to guide the process toward production-ready chip designs.
- VerCore has not been physically fabricated and was verified in simulation using Spike and ASAP7.
- Previous AI chip design efforts exist, but VerCore represents autonomous full-cycle design from spec to layout in limited scope.
- Verkor plans to release VerCore RTL source and build scripts by end of April and showcase an FPGA implementation at DAC.
