安装了encounter9.1，加载s***的lef（std_cell.lef antenna.lef),出现如下错误：

**ERROR: (ENCLF-82):The x coordinate value 4.2310

It's likely to result in placement/routing that can not be manufactured.

试过别的库，也存在同样问题，也查了一些帖子，说是lef加载有顺序，首先加载tech.lef，但是s***库中含有tech信息，不存在独立的tech.lef，所以直接加载std_cell.lef antenna.lef应该没问题的，但是...还是出问题了，希望NR给予指点，不胜感激。

看一下,你的std_cell.lef里面MANUFACTURINGGRID是0.001吗?
MANUFACTURINGGRID改成0.001，也有问题！
以为是encounter版本问题，换成8.1版本出现同样问题。现在更是不明白了，问什么代工厂提供的库，应该说是标准的库，为什么布局布线工具会加载库出现这样的问题?求高手赐教了。
在向encounter中导入用abstract提取的.lef 文件时显示M1 M2。所有的金属层都没有识别。我将lef文件中的M1。M8 全改为metal1。metal8就没有这个错误了。请问这个错误是跟。tf文件有关么?怎样能使提取出来的lef文件直接就是metal1。metal8而不是M1。M8
