描述
IniMPACT 12.xif you try to generate a SVF/XSVF file that verifies the internal flash of Spartan-3AN FPGA, you get a error:
1': Verifying device...ERROR:iMPACT - writeLength is not equal to readLength. If you play this SVF on3AN ISF, the following error occrus:
ERROR:iMPACT - On line69055,Failed ScanDR: TDO ....... does not match Expected TDO ....... EXCEPTION:iMPACT:SVFReader.c:376:1.30- Scan Data Mismatch. INFO:iMPACT:2146- Play svf failed.
解决方案
This will be fixed in a future iMPACT 12.4 version. The work around is to revert to an 11.x version of iMPACT.
