可以继续，但我这边刚才的执行已经被额度不足中断了，所以目前不能直接继续修改工程。
现在已经完成的关键修正
  • 已把 U14 的模拟麦前端从明显短接状态拆开
  • 已把 TP13 和 TP16 分离，避免调试点误并网
  • 已把 R21、Q2、IC2 的蜂鸣器控制链恢复成独立网络
当前还需要继续完成的 4 件事
  1. 复核 U14 的 MICPL / MICNL / MICPR / MICNR / MICBIAS 最终接法
  2. 给 C25、C26、R19、R20、R18 做最终命名和定值确认
  3. 审计是否还残留旧块/重复块
  4. 再跑一次完整 ERC / review，确认可交给布局
你现在可以怎么做
  • 如果你想让我继续自动修改，需要先恢复可用执行额度
  • 如果你想，我也可以先基于现在状态，直接给你一份下一步精修清单，你或我下次有额度时按清单继续
如果你愿意，我下一条就直接给你：
  • U14 模拟麦前端应如何收尾
  • 哪些网络名建议统一
  • 布局前最后检查表
给我IC2检查项
查IC2连接
跑一次ERC
查缺失去耦
给布局约束
