编程Spartan XC3S700AN时出现问题

你好，
我有一个定制的电路板，当我想对电路板进行编程时，它表示FPGA的器件ID是错误的。
确切的错误消息是：
信息：iMPACT：583  - '0'：从设备读取的idcode与bsdl中的idcode不匹配File.INFO：iMPACT：1578  - '0'：设备IDCODE：00000000000000000000000000000000INFO：iMPACT：1579  - '0'：预期
IDCODE：00000010011000101000000010010011
这对我来说很奇怪，因为在项目选项中我选择了正确的设备。
有人知道如何解决或调试这个问题吗？
我正在使用ISE 11.5完整版。
可能是因为我的时钟在引脚M1（LHCLK）上？



以下为原文

Hello,

I've got a custom made board and when I want to program the board it says that the device ID of the FPGA is wrong. The exact error message is:

INFO:iMPACT:583 - '0': The idcode read from the device does not match the idcode in the bsdl File.
INFO:iMPACT:1578 - '0':  Device IDCODE :        00000000000000000000000000000000
INFO:iMPACT:1579 - '0': Expected IDCODE:    00000010011000101000000010010011

this likes strange to me because in the project options I've selected the right device. Anybody got an idea how I can solve or debug this problem?

I'm using ISE 11.5 complete version.

Could it be caused by the fact that my clock is on pin M1 (LHCLK)?
