Answers Database 2.1i JTAG Programmer - VERIFY operation fails "too many mismatches..." errors (Spartan, Virtex...) Record #4865 Product Family: Software Product Line: CPLD Implementation Product Part: jtagpgmr Product Version: 1.5is2 Problem Title: 2.1i JTAG Programmer - VERIFY operation fails "too many mismatches..." errors (Spartan, Virtex...) Problem Description: Urgency: Hot General Description: When performing a verify on a FPGA bit file within JTAG programmer, the verify fails. The following message is observed in the pop-up window "Too many mismatches...verification aborted". Solution 1: The verify operation on all the FPGA devices through the 1.5/1.5i/2.1i jtagprogrammer is not currently supported. The workaround is to verify the done status as you would in other FPGA configuration modes by probing the done pin. Make sure that the "verify" option is not selected in the JTAG programmer.
