Problem with SignalTap in QuartusII v 13.0sp1 and device EP1S40F780C7

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?.

Hi,

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.

 

Best Regards,

Alen.
