When I keep the ILA windows under Linux (redhat) while doing a new full place and route to get new probes, using the Ethernet blaster II, when Quartus has finished the tasks (fitter, ..), Quartus GUI is not responding, no graphics refresh at all. I'm obliged to bkill quartus, re-open it and re-open the .stp to capture new traces with the ILA. Could you check if there is a bug in that area? Quartus II 21.1.0 STD Alex.

Do you see any error message or Internal Error window pop up? It will be hard to pinpoint the issue that you are facing. Does you see this issue with a specific design? Does the Quartus tool compile successfully before? Have you try to run it in a different machine? Have you check that your OS version support the Quartus software? https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-software/os-support.htmlBest Regards,Richard Tan

No error message, everything is frozen. No problem when I close the ILA windows before place and route is over. Well, If I open the ILA (.stp) after the place and route is over, the busy circle runs forever. So I can only use the ILA by closing Quartus , re open the project and re open the ILA.

I can see that there was a kind of similar issue in the past, not sure if this is still somewhat related or not: https://www.intel.ca/content/www/ca/en/support/programmable/articles/000079443.html Description Due to a problem in the Quartus® II software version 12.0 SP2 and earlier, the Quartus II GUI may freeze when adding signals in the SignalTap™ II Logic Analyzer if your quartus2.qreg file contains an invalid statement. Resolution To work around this problem, open quartus2.qreg and remove any lines that contain the text "Node_finder". The quartus2.qreg file can be found in the following location: Windows 7: C:\users\<username> Windows XP: C:\Documents and Settings\<username> Linux: ~/.altera.quartus This problem is fixed beginning with the Quartus II software version 12.1.

Is ILA the Integrated Logic Analyzer from Xilinx? If so, this is my first time seeing a customer using Quartus with ILA. Any reason why you want to use ILA instead of our Signal tap logic analyzer? p/s: the KDB is not applicable as the Quartus impacted is old version.

I mean't signal tap (for internal logic analyzer). I did use ILA on Xilinx too for a Xilinx FPGA. In this case this is an Altera cyclone V FPGA so I use Quartus/signal tap.

Quartus II 21.1.0 STD and ILA opened windows freezes GUI on LINUX at end of fitter.

I try with bigger design but unfortunately not able to duplicate the issue.
Since I am not able to duplicate the issue, there is not much that I can help on this.
Perhaps uninstall and reinstall the Quartus may works.

  Hi,
  
  While scrolling the setup window under red hat linux using the mouse scroll wheel,
  
  Quartus crashed with this error.
  
  This may point to a problem with the stack size in the ILA.
  
  Would it be possbible to provide a way to increase the stack size of Quartus or the jtag client,
  
  or a quartus patch, to try at my side if that solves the issue?
  
  *** Fatal Error: Unhandled exception

  Exiting...
