无机酸有空帮忙看看这个吗？ DONE did not go high.
使用Xilinx的Spartan-3AN系列芯片，软件版本为：ISE9.2.04i
配置时：
80％的结果是：ISE报告下载失败（Program Failed），但是断电重启后，程序实际上下载进了芯片内部Flash，并且能够自动加载运行。应该是“假”失败。
15％的结果是：ISE报告下载失败（Program Failed），断电重启后，程序没有运行。应该真的是下载失败。
5％的结果是：ISE报告下载成功，并且能够马上重新加载运行。断电后也能够运行。
ISE报告下载失败（Program Failed），给出的信息如下：

使用市场上买的并口下载线和USB下载线，都一样的结果，无非是并口的下载速度慢点。
哪位大侠帮忙指点下，这是怎么回事？ FPGA芯片采购自Xilinx的官方代理商好利顺(Nu Horizons)，芯片本身应该没有问题。
跟下载相关的电路接法为：
PROG_B、DONE、INIT_B用4.7k上拉；
M1、M0用10k上拉，M2用200欧姆下拉。
参考的Xilinx官方开发板电路。 细看ISE给的提示信息：
'1': Erasing device...done.
'1': Erasure completed successfully.
......擦除成功。
'1': Programming device...done.
'1': Programming completed successfully.
......编程成功。
'1': Verifying device...done.
'1': Verification completed successfully.
......校验成功。
偏偏最后给个：
'1': Programming terminated. DONE did not go high.
DONE是FPGA的输出，又不受哪里控制，所以令人束手无策。郁闷！ ISE 9.xx的bug，对spartan 3AN支持有问题，
升级到10.1及以上就对了，
这个问题我两年前遇到过。 我试试看。
可是坛子里很多人说ISE的更高版本不如9.2的稳定... 遇到过，感觉还是软件问题，每次配置FPGA都要重新打开软件 我也出现了这样的问题，不知道如何解决，捉急 无机酸养伤呢，暂时没工夫
