读spef时tie cell 的error,warning

随风的叶

大家好，小弟用starrc抽取spef后用pt读入spef，发现出现很多tie cell 的error和warning,写出pt.v文件之前，change name -rules verilog -hierarchy了，不知道为什么这么多tiecell 的errror和warnin，如下所示：Error: Cannot find port/pin 'TIEL_HVT!U527/ZN' in design 'oc8051_top' (DES-002)

change_names了，save_mw_cel了么，然后再starxt extraction

  出  pt.v之前change_name了，然后要save_mw_cel ？之后没有save_mw_cel，有什么影响？。。。

要的，starxt抽取的是mw cel view本身啊，如果不save，他怎么知道你change name等操作了呢

   谢谢版主，昨天想了下确实要保存cel，
