请教：Synplify，ISE，Modelsim联合后仿真问题！

各位老师好：小的有一问题请教！
我在用ISE和Modelsim作后仿真时,提示如下错误信息,我实在搞不定了,请您帮我看看!多谢了！

是不是在modelsim里面没有指定sdf文件的路径？
见下面的路径：

回复 2# njithjw


    遇到同样问题，路径添加了还是产生同样的错误

njithjw 发表于 2011-4-3 20:16:18

你把上面图中的这两个选项也选上
Disable SDF warnings
Reduce SDF errors to warnings
然后再重新仿真一下试一下。
如果还有问题，你能不能把你的错误报告帖上来看一下，现在这样交流根本不知道是什么错误。

不好意思，没看到上面的错误信息。
如果还搞不定，最好能把你的工程发上来，让大家帮忙一起看一下，论坛里面还是有很多高手的。
