Error: Can't Launch Questa Intel Starter FPGA Edition from Quartus Prime Pro tool.

[SohanHPatel]

I have installed Quartus prime pro Edition Version 23.1.0 and Questa Intel Starter FPGA Edition-64 Version 2022.4 linux_x86_64 on linux machine (Ubuntu 22.04.3 LTS). Whenever I tried to launch Simulator from Quartus prime tool by setting executable location then following errors occur.

Error: Unable to launch questasim software -- make sure the software is properly installed
Error: couldn't execute "vsim": no such file or directory
Error: while executing
Error: "open "|\"$gl_ext_cmds(vsim)\" -c -do $gl(tmp_cmd_file) 2>@1" r" POSIX ENOENT {no such file or directory}Error: Compilation was NOT successful. 4 errors, 1 warnings

But when I tried to open simulator manually by ./vsim command from same executable location then Simulator is working. 

Can you please help me?

Thanks,
Sohan Patel

Hi,

I tested without problem check the video attached below. May be try to re-install. When you install the Quartus Tool make sure ticking the Questa Starter Edition to install together.

Thanks,

Thanks for your respose @ShengN_Intel .

I have already tried for re-installing the same. As your attached video, tried same but getting this error although have selected the path where vsim is located.

Hi,

Check this forum case link https://community.intel.com/t5/Intel-Quartus-Prime-Software/Questa-exe-not-being-seen/m-p/1539328#M80514. I had reported this bug to internal team already.

Please following the exact steps below for workaround (as mentioned in video):

1.After re-installing the software tool.

2.Specifying the Executable location path as ../questa_fse/win64 and Output directory path then ignoring the warning message, click Start Compilation.

3.If see this message Specify the simulation tool executable location. pop up, click OK to close the pop up, then Click at the Executable location tab and then press Enter. After that Start Compilation.

4.If still can't, install both questa_fse and questa_fe then follow the steps before again.

Thanks,

Regards,

Hello @ShengN_Intel ,

Have followed these steps and re-installed as well with questa_fse and questa_fe but again facing the same problem.

Hi,

Do you mean you re-install the whole Quartus and Questa simulator?

If still really can't, probably temporarily use command check this link https://www.intel.com/content/www/us/en/programmable/quartushelp/17.0/mapIdTopics/jka1465596847489.htm to workaround

Thanks,

Ohh great! Now working but facing another issue related to License file.

If I invoke vsim from bin directory then it's working as I already set LM_LICENSE_FILE variable but during running from Quartus tool, it's showing error related to License file.

Have attached the screenshot for the same.

Thank you for your time @ShengN_Intel.

Hi Sohan,

Check this link https://www.intel.com/content/www/us/en/docs/programmable/683472/22-1/and-software-license.html and this link https://www.intel.com/content/www/us/en/programmable/quartushelp/17.0/mapIdTopics/jka1465598270294.htm

Specifying the following commands below in .cshrc or .bashrc file (Linux):

export LM_LICENSE_FILE=<path to license>:$LM_LICENSE_FILE

setenv LM_LICENSE_FILE "<path_to_license_file>"

Note: Linux: You must source your .cshrc (source ~/.cshrc) or .bashrc (source ~/.bashrc) file before restarting the software.

Thanks,

Yes these things have solved the license error. but then only simulator library is getting compiling for long time. Simulator is not getting open. How can I open Simulator in quartus prime pro edition.

Right now I am following these steps.
1. Open Project.
2. Tools -> Launch Simulator Compilier Library -> then setting execuatable location path and compiling it.


Am I following right method or is there any other way to launch the compilier? (As in Lite edition, there is separate menu for Run Simulation likewisw).

Thanks,
Sohan

Hi Sohan,

If the problem still can't be resolved, follow this video link https://www.youtube.com/watch?v=e5kHFiAVcRI&t=105s to specify the LM_LICENSE_FILE

Hi Sohan,

FYI. There're some differences between Quartus Pro Edition and Quartus Std/Lite Edition in terms of simulation.

Quartus Std/Lite Edition got nativelink simulation (launch simulator within Quartus) while Quartus Pro Edition don't have nativelink simulation (launch simulator outside Quartus).

Quartus Pro Edition simulation have to use simulation setup script check this link https://www.intel.com/content/www/us/en/docs/programmable/683870/21-3/sourcing-modelsim-simulator-setup-scripts.html. The simulation steps can be checked from document https://www.intel.com/content/www/us/en/docs/programmable/691278/21-3/generate-a-simulator-setup-script-template.html and video https://www.youtube.com/watch?v=eviC0jP90ZA&t=1s

Launch Simulator Compilier Library is something to compile the simulation library only, it wouldn't launch the simulator.

Thanks,

Ohh!! Okay thanks @ShengN_Intel . Will look at these steps.

It's been a great help.
