我用的smic 0.18io库,刚开始连接电源pad时出现
Begin power routing ...
**WARN: (ENCSR-1256): Cannot find any CORE class pad pin of net VDD. Check net list, or change port class in LEF file, or change option to include pin in given range.

我记得做过一个tsmc的lab,它的pad pin有一项CLASS CORE ;而我这个smic没有这东西
我加上以后就能连上了,请问这是怎么回事,没有别的办法了吗,库本来是没有CLASS CORE ;的啊 |
