AI总结：
针对3D-IC布线后ECO手动操作的缺陷，提出AgenticECO智能体框架搭配EcoRoute最小干扰布线层，在9个缺陷案例中表现优于基准方法，且所有结果通过各类设计检查，相关材料已开源。
AI中文摘要：
随着摩尔定律放缓，行业正转向三维集成；然而在合并的三维集成电路（3D-IC）流程中，已布线设计会出现键合级缺陷，这类缺陷在二维集成电路中无对应情况，且布线后工程变更指令（ECO）仍为依赖专业知识的手动工作。更糟的是，标准的“先编辑再完全重布线”做法会将修复与布线器变动纠缠在一起，因此无法将签字编号归因于触发该编号的编辑。我们提出AgenticECO，这是一个基于证据、使用工具的智能体工作流，用于开源TaiWei流程上的3D-IC ECO，搭配EcoRoute——一个最小干扰的ECO布线层，可驱动未修改的固定布线器，从而使修复可归因于其对应的编辑。在相同预算下的9个匹配自然缺陷案例中，AgenticECO成功修复7个，而完全重布线和标准修复各成功2个；在已修复案例中，平均干扰为0.66%，且未触及任何时钟网络；在相同密封契约下的跨主干重运行则成功修复全部9个案例。对照研究表明，在保持约束下，修复操作是必要的；感知占用率的选择可获得合法着陆点而非修复成功；在收紧时钟条件下，最小干扰会使接受变为拒绝。三项预注册视觉研究将像素工具的边缘定位在有争议的着陆点，一项预注册盲诊断可准确恢复所有预留的注入缺陷，这是唯一无错误编辑的分支。所有接受的结果均通过布线、提取、最大/最小时序、DRC和结构等价性检查。代码、环境及每轮审计工件作为补充材料发布。
英文摘要：
As Moore's law slows, the industry is turning to three-dimensional integration; yet in merged 3D-IC flows, routed designs expose bond-level defects with no 2D analogue, and post-route engineering change orders (ECO) remain manual, expertise-bound work. Worse, the standard edit-then-fully-reroute practice entangles a repair with router churn, so a signoff number cannot be attributed to the edit that motivated it. We present AgenticECO, an evidence-gated tool-using agent workflow for 3D-IC ECO on the open-source TaiWei flow, paired with EcoRoute, a minimal-disturbance ECO-routing layer that drives the unmodified pinned router so a repair is attributable to its edit. Across nine matched natural defect cases under identical budgets, AgenticECO clears seven versus two for both full reroute and stock repair, at 0.66\% mean disturbance over cleared cases and zero clock nets touched, and a cross-backbone rerun under the same sealed contract clears all nine. Controlled studies show that the repair moves are necessary under preservation, that occupancy-aware choice buys legal landings rather than repair success, and that under tightened clocks minimal disturbance flips accept versus reject. Three preregistered visual studies localize the pixel instrument's edge to contested landing sites, and a preregistered blind diagnostic exactly restores every held-out injected defect, the only arm with zero wrong edits. Every accepted result passes routing, fresh extraction, max/min timing, DRC, and structural-equivalence gates. Code, environment, and per-episode audit artifacts are released as supplementary material.
