    Noticed in the GUI message window at the start of a build a message stating that the ipgenerate tool was using an INI file (quartus.ini). Curious what might be in it I took a look and low and behold found this line. So it's apparently some debug feature of Quartus. No idea why it was set on mine

    dcalc_force_negative_transitions_to_zero_and_print_debug_warning=on

    Set it to off and those files are no longer created. Problem solved :-).

I've never seen this created before, but you can try turning off the snapshot feature in the compilation settings since you mention you get this at each stage of the fitter. But the compiler generates binary info for compilation results, not a random text file.

Do you have an .ini or some other unique feature enabled?

Snapshot is off. The base for this project was the Cyclone 10 GX Dev kit so I'm not sure what might or might not be enabled. The weird part is a Google search for that file name has zero hits. Not a huge deal but very strange. Thanks for the replies.
