I have all the time this error:
Error (261009): Cannot run SignalTap II Logic Analyzer. SignalTap II File is not compatible with the file programmed in your device. The expected compatibility checksum value is 0x2DB51B6F; the value read from your device is 0x9EDA8DBF
I was checking on the forum different problems and I try all that I read and the error persist:
-Remove the DB folder/output files/ incremental compilation
-Remove the .stp file and regenerate
I have also found another strange behavior, when in the top level I coment some models then it works perfecly, but if not give me the same error of the checksum.
I have to say that the design hasn't any critical warning or warnings about the design rules...
Someone have experience with this problem?.
Can you please check the below solution note & let me know how it works in this case,
I already read this information and I use always the basic AND trigger in the SignalTap.
And there is a strange behavior because in my top level FPGA if I add some entities I get the error, but with others not.
