社区实测：最优位机制下 1092 电路无一超越Community test: 1,092 circuits, none beats incumbent
社区成员 JinShouZhiqywg 解析 TapeOut 挖矿机制：每个任务设一个最优位，由按「面积×深度³」计算成本最低的 NAND 电路占据，Behemoth 上最优位日产出约 100 BEM。以 8×8 乘法器为例，参考电路为 600 门、深度 68，当前占位电路 689 门、深度 20，按该指标成本低 34 倍。其用 Yosys 与 ABC 跑 14 个任务，得到 1092 个正确电路，无一超过现任占位者；官网推荐流程在 14 个任务中有 6 个比参考电路还差。Community member JinShouZhiqywg breaks down TapeOut mining: each task has one optimal slot held by the NAND circuit with the lowest cost under area × depth³, and the best slot on Behemoth yields about 100 BEM per day. For an 8×8 multiplier, the reference circuit is 600 gates at depth 68, while the current holder uses 689 gates at depth 20, 34x cheaper by that metric. Running Yosys and ABC across 14 tasks produced 1,092 correct circuits, none beating the incumbent; the official recommended flow was worse than the reference on 6 of 14 tasks.
