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～
