我用QuartusII做的一个简单设计，在编译完成后出现下列对话框：

File_mydesign_time_limited.sof contains one or more time_limited megafunctions that support the OpenCore plus feature that will not work after the harework evaluation time expires. Refer to the massages windows for evaluation time details.

无法下载到目标板上，消息窗口如下：

不知怎么回事？哪位高手指教一下，谢谢～～～

 one or more time_limited

你有一个或几个IP过期了！你可以重新找破解，好像本版就有。

好的，谢谢版主～

重新破解还是不行啊……

上面的问题还是存在，无法下载到目标板上，出现下列对话框：

Click cancel to stop using Opencore plus IP

版主版主在不在啊？？

我出现了同样的问题...

请高人指点，谢谢！

你的license有问题啊，重新找一个license，保证所有的core都可以用，就可以了。

我也一样,楼主你的问题有解决了没有啊?
