An agent autonomously builds a 1.5 GHz Linux-capable RISC-V CPU
An AI agent built a functional RISC-V CPU from a text spec in just 12 hours.
Chip design startup Verkor has demonstrated a significant leap in AI-assisted engineering with its Design Conductor (DC) agent. According to a paper, the AI autonomously designed 'VerCore,' a fully functional RISC-V CPU capable of running Linux, from a single text specification. The agent handled the entire process—from writing the register-transfer level (RTL) code in a hardware description language to performing the physical design—culminating in a final GDSII layout file ready for manufacturing. The resulting CPU hits a target clock speed of 1.5 GHz, implements a 5-stage pipeline, and is built on the ASAP7 semiconductor process platform.
The achievement highlights both the potential and current limitations of AI in complex hardware design. The AI completed the task in approximately 12 hours, a fraction of the time required by human engineers. However, the success was dependent on an extremely precise and measurable input specification; omitting a single performance metric like CPI (cycles per instruction) could lead to a poorly optimized design. While the output is functionally 'working'—similar to how Anthropic's Claude created a basic C compiler—experts note it lacks the polish, error handling, and diagnostics needed for production. Verkor is reportedly already working with top fabless semiconductor companies to integrate DC into their workflows to accelerate time-to-market.
- Verkor's 'Design Conductor' AI agent built a Linux-capable RISC-V CPU from a text spec in ~12 hours.
- The resulting 'VerCore' design achieves 1.5 GHz clock speed using a 5-stage pipeline on the ASAP7 PDK.
- Success required hyper-specific input specs; a missing CPI target led the AI to create suboptimal designs.
