后仿问题:Compiled SDF file was not found

我在做后仿的时候出现了下面的错误,主要的错误是:Compiled SDF file was not found.
请高手解决一下.搞了好久了,老是有错.
下面是整个过程的记录:

呵呵。.以前我碰到过...
建议你查找SDF文件在那里。修改FDO文件..有时候是FDO生成的就有错.

同错，请高人指点

Failed to parse SDF file
有没有人遇到这个问题?很想知道

必须在仿真的test_bench中，指定SDF文件的位置。

    我也出现同样的错误,您说必须在test_bench中指定SDF文件的路径，那么请问如何指定啊?！
我的邮件zouxigyu666@yahoo.com.cn，您如果方便发个邮件给我吧，不胜感激！
    多谢了！

lz问题解决没?同遇到这样的问题

把netgen/par文件夹copy到modelsim工程目录下可以解决compiled sdf file was not found的问题

点击simulate,选择SDF项，点击Add，指定.sdo文件
将左下角的两个复选框勾选上（不然要报错，可能是软件的BUG）
OK！

将左下角的两个复选框勾选上，这样忽略错误可以么?

将.sdo文件复制到modelsim工程文件目录下就可以了

谢谢你的建议
