Problem with Signal Tap Logic Analyzer

Hi,

I'm using Quartus 21.2.

When I use the signal tap logic analyser I get a crash.

The FPGA works fine with the loaded content. But the logic analyser crashes with this message:

End-trace

 

The programmer worked successfully.

I tried several simple 2 signal logic analyser, that does not change anything.

With Quartus 21.1 I had no problem.

What is wrong?

regards 

Michael

Hi @MSenk1 

 

I haven't seen this internal error(IE) before. Could you help to share your design .qar file that could duplicate this error?  As without duplication of the error from our side, it would be hard to find a workaround/solution. 

* If your design is confidential, please help to create a simplified design that can duplicate the IE. 

Please help to provide any specific steps on when this IE occurs, does it crash when you try to open the Signal Tap tool or running the tool ? 

Please expect that any work involving engineering will take some-time (a few days to a few weeks) depending on the complexity of the issue.

If your project is urgent, I would recommend to use Quartus 21.1 as a temporary workaround. 

Best Regards,
Richard Tan

For anybody wondering about the solution, this is what helped me to solve the problem with the same error message:

 

1. Disconnect hardware

2. Launch signaltap

3. Press "Setup..." button

4. Connect hardware

5. Once hardware appears in the window, reduce JTAG frequency
