EEBench grades agents on circuit design in atopile; Claude Opus 5 leads at 61.6%
The atopile team published EEBench, a benchmark that grades agents on 13 circuit-design tasks written in atopile. The harness builds each design and runs SPICE checks at worst-case tolerance corners. The post says Claude Opus 5 led V1 at 61.6%. One failed design used a 22 uF capacitor that gave about 11.4 uF under bias. V1 is simulation only.
