LEF版本问题

时间:10-02 整理:3721RD 点击:
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WARNING (LEFPARS-2020): FOREIGN statement in VIA is obsolete in version 5.6 and later.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

哪位大侠回答下啊

问题解决了吗?怎么解决的,我也遇到了同样问题

改LEF的版本

怎么改?直接在lef内改吗?

有LEF版本的描述语句的
在前面加一句就行了
version 5.6貌似是这样

谢了。还有个问题望指教:
Loading Lef file ../../../eda/lib/stdcell6.lef...
**WARN: (ENCLF-102):Two layers 'M1' and 'V1' specified in
SAMENET spacing rule have different type. To specify a SAMENET
spacing rule between a cut layer and routing layer, the first
one must be a cut layer. The rule is ignored.

Initializing default via types and wire widths ...
**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.
**ERROR: (ENCLF-82):The y coordinate value 0.8590
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。
