Diffusion models could already sketch plausible layouts, but hitting real electromagnetic targets was the hard part. Full-wave simulators check those targets accurately but are slow and not differentiable, so earlier approaches leaned on faster differentiable \"surrogate\" models that are less trustworthy. SRD splits the labor: the cheap surrogate's gradient suggests a direction to change the design, then the accurate simulator searches along that direction to pick the actual update.\n\nPCB design, especially for antennas and wireless hardware, is normally a loop of guess, simulate, and adjust, where each simulation costs real time. A generation method that lands closer to spec on the first few tries could meaningfully shrink that loop instead of just producing one plausible-looking layout. The paper reports layouts landing up to 21.2% closer to target specs than prior methods on familiar design types, and up to 19.8% closer on designs unlike anything in training, the harder test of whether the approach actually generalizes.\n\nThose numbers come from the paper's own simulated benchmarks, not a board that has been etched, soldered, and measured on a bench, so the real test is still ahead.","[\"ai\",\"diffusion-models\",\"pcb-design\",\"rf-engineering\"]","2026-10-01T04:00:00.000Z","2026-10-02T15:14:43.388Z","2026-10-02T15:14:49.553Z","published",null,[],"ai",[24,26,27,28],"diffusion-models","pcb-design","rf-engineering",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.38363",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,90,95,100],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",5721,"2026-10-01T19:45:44.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",829,"2026-10-01T17:31:56.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",437,"2026-10-01T18:10:00.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",317,"2026-10-01T22:00:00.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",198,"2026-10-01T17:38:48.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",168,"2026-10-01T18:35:55.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",155,"2026-10-01T19:54:10.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Dev Tools","dev-tools",96,"2026-10-01T16:57:03.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Software","software",93,"2026-09-30T21:41:11.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",90,"2026-10-01T21:55:22.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
