我最近做了块板子，cpld用的是xc9572xl,下载程序时出现下面错误：
ERROR:iMPACT:583 - '1': The idcode read from the device does not match the idcode in the bsdl File.
INFO:iMPACT:1578 - '1': Device IDCODE : 00000110011000010100010010010011
INFO:iMPACT:1579 - '1': Expected IDCODE: 00001001011000000100000010010011
PROGRESS_END - End Operation.
Elapsed time = 0 sec.
PROGRESS_START - Starting Operation.
Cable is not connected.
cable用output中的autoconnected能连上，请各位大侠帮忙看看可能是什么原因造成的
