Error while trying to run Questa simulator

Hello,

I too had the same issue on a fresh install of Quartus Prime 22.1std.0. I think I figured out why it is happening. In one of the tcl files, there is an erroneous double quote which, when removed, allows me to successfully launch Questa from Quartus.

For me, I have Quartus installed in the default location, so when I navigate to "C:\intelFPGA_lite\22.1std\quartus\common\tcl\internal\nativelink" there is a file called qnativelinkflow.tcl .Open that file and go to line 122 which should say 'set questa_installation "$questa_fse_drectory'. Remove the double double quote and try launching the simulation from Quartus again. That worked for me.

Have you set the EDA Tool location in the Quartus? It seems to be the root cause.

You may checkout this user guide on Specify EDA Tool Settings.

https://www.intel.com/content/www/us/en/docs/programmable/703090/21-1/specify-eda-tool-settings.html

You may use the design example and go through the simulation flow provided in the user guide.

Best Regards,

p/s: If any answer from the community or Intel Support are helpful, please feel free to give best answer or rate 4/5 survey.

From that user guide, I believe I have everything set (see images for screenshots of my settings), but I'm getting the same error message. Thank you for your help already, and I hope you or someone else can discern whatever it is I'm doing wrong:

Ahh! It mentioned that:

c:/intelfpga_lite/22.1std/quartus/common/tcl/internal/nativelink/modelsim.tcl missing "

Could you check is the modelsim.tcl file in that respective folder?

A successful simulation flow should generate log messages like this:

Info: Starting NativeLink simulation with Questa Intel FPGA software

Sourced NativeLink script c:/intelfpga/21.1/quartus/common/tcl/internal/nativelink/modelsim.tcl

Info: Spawning Questa Intel FPGA Simulation software

Hi Richard,

Thank you again for your speedy reply. The file certainly seems like its in the correct place.

James

I am quite stump. I try to install quartus lite 22.1 and questa starter edition and able to invoke the simulator.

Could you try to run the Quartus as administrator?

Else, my last solution is to try reinstall Quartus and questa altogether.

Richard Tan

Hi,

Do you able to resolve the issue?

Richard Tan

Hi Richard,

Thank you for checking in, but I reinstalled Quartus and questa and the error was the same.

James Sherman

Hi,

Do you able to resolve the issue based on the solution provided by the community?

Richard Tan

Thank you all for the feedback provided on this issue.

The engineering team has aware of this issue and they will plan to fix this. (usually will takes some time depending on the issue complexity)

Since this issue will be planned to be fixed and a workaround is available, do you need further help in this case?
