Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Circuit, board and chip design
Designing analog and digital circuits, writing hardware description code, and laying out boards and chips.

Where this applies
An academic re-evaluation of Google's reinforcement-learning macro placement using public benchmarks and a commercial place-and-route tool for post-route power, performance and area. For large macro-heavy designs, human experts beat the method in 5 of 6 comparisons; a stronger simulated-annealing baseline gave better wirelength in 7 of 9 cases, while the method gave better total negative slack than simulated annealing in 6 of 9 cases. The authors say questions about the method's scalability remain open. A handful of designs; it does not measure engineers' work.
What this means
On the largest designs tested, experienced people still placed blocks better than the published AI method.
What it does not yet show
A handful of benchmark designs; results are mixed on some measures.
What you can check
Open arXiv 2302.11014 and find "human experts dominate" in the v3 PDF.
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
