Quartus won't let me use Signal Tap. Can't elaborate "sld_hub:auto_hub"

Hello, I've been dealing debugging issues for quite a while with my FPGA design. I had to use Signal Tap for advanced debugging, but for some reason it can't be used. I am just following the tut...

Well, the next thing I'd try is recreating the .stp file from scratch because it's what causes alt_sld_fab to be synthesized. First, disable Signal Tap in the project settings, then close and reopen the project. Then, create a brand new .stp file, choosing to enable Signal Tap in the project when you save the file. Again, I didn't have a failure when I compiled with the existing .stp, so I don't know if this will do anything for you.

I'm not sure why, but maybe even the signals you are tapping are causing the issue. See if you can compile with an empty .stp file. If that works, re-add the signals you're tapping group by group. I doubt this is the issue or will do anything, but I don't know what else to try.

Is the board with the device you are using currently attached to the machine you are using to compile? Again, that shouldn't cause any issues, but try disconnecting it before compilation.

    I tried different examples with different . stp files, but I still get the same errors. Even the ones from design store causes the same problem, so it has nothing to do with the content of the .stp file.

    I am just trying to compile the design, I don't know what board has to do with errors, but I tried anyway and nothing changed.

    I don't event know what is going on right now. 😪
