When I use 6.2i SP2 or 6.2.i SP3 iMPACT, my device fails to configure via JTAG, and the SVF, XSVF, or ACE files that are generated do not configure the target FPGA devices correctly. Using a previous version of iMPACT with the same ".bit" file to program or to generate the file will correctly configure the device.
The problem can affect Spartan-II/-E and Virtex/-E/-II/-II Pro devices.
1. Done goes High, but the board does not function correctly.
2. TDO mismatch errors occur. (For System ACE CF applications, this will cause the ERRLED to light.)
The programming issue will be fixed in the 6.3i software release, which is scheduled to be available in August, 2004.
The TDO mismatch issue for file generation will be fixed in the 6.3i Service Pack 1 software release, scheduled for September, 2004.
A patch is currently available for 6.2.03i iMPACT.
