在下载时候，我遇到的问题：isp3 iMPACT - "ERROR: iMPACT:583 - '2' The IDCODE read from the device does not match the IDCODE in the BSDL file" 这是在XILINX网上看到的帮助，小弟还是看不懂。那位高人指导下。谢谢。
1. Older CoolRunner devices may have a Philips IDCODE instead of a Xilinx IDCODE. (Xilinx acquired the CoolRunner line from Philips.) If iMPACT reports this error message for a CoolRunner device, a slight modification to the IDCODE register in the BSDL file is required. In the IDCODE Register, "X" out the Manufacturer bits of the IDCODE:
"0000" & -- Version "0100100010001011" & -- Part Number "XXXXXXXXXXX" & -- Manufacturer "1"; -- Mandatory
NOTES: a. The part number in this example may differ from the part number in the BSDL file for your device. b. The BSDL file that requires this modification is the "generic" xcr*xl.bsd file located at $xilinx\xpla3\data. iMPACT does not use the package-specific BSDL file. c. Restart iMPACT to ensure that the modified BSDL file is loaded.
