SOPC 在generation时遇到的问题

系统设计好之后点击“generator”，提示：
Warning: reconfig_request_pio: PIO inputs are not hardwired in test bench. Undefined values will be read from PIO inputs during simulation.

之后一直停在这，CPU占用50%（perl.exe程序占用），
在任务管理器中结束perl.exe程序后提示“failed to refresh ptf file”
然后开始“generation”，同样，停在这儿了，还是perl.exe占用50%的cpu，
在任务管理器中结束perl.exe后，提示“system generation failed”。
我的系统是Windows Server 2008，quartus 8.1版本，不知是不是版本不兼容?

楼上的，不能这样灌水吧！

灌水的不地道呀

还是由于不兼容引起的，参考国外的帖子，解决方法如下（原帖针对7.2版本，不过对8.1也适用）：
HOW TO MAKE NIOSII EDS VISTA COMPATIBLE
1) Download the Cygwin-installer from http://www.cygwin.com/setup.exe
2) Run install.exe while online (i did not check if it makes provision for a proxy server )
3) When asked the install directory ( Default c:\cygwin ) browse to and select c:\altera\72\quartus\bin\cygwin as the install dir
4) Let install update cygwin to the newest version
Just tested it on Vista Ultimate with full current updates Generate in SOPC builder now works fine , compile is ok and compiling Hello world works correct
====================================
It's tricky when you update cygwin files..that is , you cannot update all new files,but only default ones.
You might rename .../cygwin/etc to .../cygwin/etcold and try again.By the way, when running cygwin setup.exe,choose Dos/text as Default text file type.
7.2 Sp1 updated cygwin files,but still not working by default. Anyway , quartus and nios now support Vista better than before. Hope working on server2008！
Good Luck！
