rt～就是装了sp3还需要装sp1和sp2吗？

另外一个问题是，我用的是ise9.1,在实现的时候报了个错，在xilinx网站上查到的解决办法说是：

This problem can occur if the project is out of sync with the files in the project directory.

In some cases, the project can be corrected by running Project -> Cleanup Project Files. Typically a project in this state will need to be recreated.

This problem has been fixed in the latest 9.2i Service Pack available at:
http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 9.2i Service Pack 1.

我用了cleanup 命令，还是不行。

按照他的回答，要安装 9.2i Service Pack 1,可是这个能装到9.1上吗？

谢谢啦～

哦, 是这样

那xilinx怎么让我往ise9.1上装9.2的sp呢?

谢谢
