u"""对**布线器算出来的几何**自算净距 —— 不过桥接、不等 DRC。
|

/c/Python314/python .claude/r2/router_check.py [--list N]
|
||||
|
||||
## 为什么要有这个
|
||||
|
||||
EasyEDA 的 DRC 一轮要 ~10 分钟（下发 → 重铺 → 读面板），而且**明细行读不回来**
|
||||
（`drc_read.py` 能读到分类计数，读不到每一条的对象和坐标）。
|
||||
靠它迭代等于每改一行代码等十分钟、还看不到是哪两个东西撞了。
|
||||
|
||||
⇒ 这里按**真实几何**（线段-线段 / 线段-矩形 / 圆-圆 …）自算，
|
||||
判据和设计规则一致（净距 `MIN_CLR`）。布线器的占用图是 0.25 mm 网格上的
|
||||
轴对齐盒子，是个**近似**；这个检查器算的是精确距离，两者的差就是 DRC 会报的那些。
|
||||
|
||||
⚠ 判据只覆盖「铜与铜」。**铺铜（pour）与过孔/钻孔的关系不在这里** ——
|
||||
那一支归 EasyEDA 自己按规则裁，DRC 里显示成「到 过孔 / 到 钻孔」。
