Quartus II quits unexpectedly compiling w/ .stp file, but compiles fine without it

Honored Contributor I



As the title states, my design can compile just fine if I remove the .stp file from the project. I want to test the design running on the board before I started connecting to other modules. I add an .stp, set the clock, trigger and nodes to observe. Then I have to recompile / rapid recompile. My compilation stops when it gets to 'saving pre-synthesis snapshots for 2 partition(s)' 


I did some googling and found that some people have said related issues can occur if there are multiple pin assignments to the same pin - I don't think that applies here as I've checked my .qsf file. 


Here is the report:

This happens occasionally. Try deleting the db folders to start a clean compilation. If the problem continues, there's probably a specific problem in your design, or you have revealed a Quartus bug.

I have internal error with 17.1 and 16.0 (but in other file). It was because in Signaltap were added signals from chain of triggers, that can automaticaly replace with shift register. Without stp no errors, with internal error. When i turn of "Auto Shift Register Replacement" in Compiler Settings -> Advanced Settings (Syntesis), i have no errors. Check this option or others replacement options.

Thanks for the tips guys. I was able to fix the problem by creating an identical but new project. I think this may be due to device/license changing after project conception. When I made a new project with the license I needed from the start, everything worked fine.
