用foundry给的LEF,出现类似如下warning:
Loading Lef file ../LEF/head_CZ6H_4AL.lef...
WARNING (LEFPARS-2020): FOREIGN statement in VIA is obsolete in version 5.6 and later.

这版本问题要如何解决啊

   谢了。还有个问题望指教:

**ERROR: (ENCLF-82):    The x coordinate value 4.2310
in pin 'A' in macro 'XOR2CLKHD4X' is not on the manufacturing grid.
It's likely to result in placement/routing that can not be manufactured.

这是什么原因?

第一个问题是lef里面有些描述不适用于5.6版本的lef,需要转换版本。第二个问题是说你的金属层和孔的层被定义为不同两层,定义他们之间的距离必须是cut layer和绕线层,所以规则被ignore了。
