Astro 中metal & blockage overlap

我用tsmc18工艺在Astro中布局布线完成后，在Astro中做DRC检查，结果报错
Error TypeNumDescription
Met1 Overlap8metal1 & blockage overlap
Met2 Overlap72metal2 & blockage overlap
Met3 Overlap36metal3 & blockage overlap
Met4 Overlap36metal4 & blockage overlap
Met5 Overlap36metal5 & blockage overlap
这些错误都提示位置都在IO PAD上
请问这是怎么回事，怎么才能解决呐?

很奇怪的是我的 detail route and search repair 中 violation 的数目是0.

同问。同问

同问，同问！

可能是假错， pad filler引起的吧，
直接做calibre吧， 别管他

我做的没有pad filler 怎么也有类似的错误呢?

做calibre吧， pr工具的drc 很多是假的
