Nvidia and ChipAgents launch Build-A-Chip-Bench for AI chip design
Nvidia and chip-design automation startup ChipAgents jointly released a benchmark called Build-A-Chip-Bench that tests whether AI agents can carry an end-to-end digital chip design flow — architecture, microarchitecture, RTL, functional verification, logic synthesis, floorplanning, placement and routing, clock-tree synthesis, timing and power signoff, and physical verification — all the way to tapeout readiness. ChipAgents CEO William Wang said the evaluation focuses on whether agent systems can sustain reasoning and decision-making across every stage while meeting functional, timing and strict power, performance and area (PPA) requirements. In initial testing, the best-performing agent, powered by Anthropic's Fable 5.1, scored just 16.6%, which the companies present as evidence of how far AI remains from true autonomous chip engineering. ChipAgents was founded in 2024 and has raised $134 million from investors including B Capital, Micron and MediaTek.
It moves AI chip-design evaluation from single tasks toward a near-tapeout end-to-end flow and establishes a still-low baseline score for judging how far the field has to go.
