Questa Compile error vcom-212 Stack hard limit

Hi

We have installed Intel Quartus 23.4 with all of dependencies and modules on RHEL 8.7. When we run Questa and try to compile a model we are getting an error message stating

Error (suppressible): (vcom-212) Stack hard limit 67108864 < 67108864

Contact your system administrator to set the hard limit above this value

I have checked the current stack limit on our server is 64MB (65536KB).

We have faced the same issue on RHEL7 box with Questa version 22.

Is there a minimum limit for hard stack for carrying out the compilation of models within Questa from version 22 and onwards? If yes can you please tell us that bottom limit and point me to that documentation as well that contains that information.

Thanks

Umar

    You can try increasing the stack hard limit for the vcom compiler. You can do this by setting the VCOM_STACK_SIZE environment variable to a higher value. For example, you can set it to 134217728 (128 MB) by running the following command before starting Questa e.g.:


    export VCOM_STACK_SIZE=134217728


    After setting the environment variable, try compiling your model again.

    Let me know.

    Hi,

    We have tried the above mentioned solution of setting environment variable and can confirm that unfortunately this does not work and we still have the same issue and are unable to run any modelling simulation in Questa.

    Regards,

    If you cant see itself, you probably need to contact you admin IT to set it for you.

    Hello Syafieq,

    I am sorry, I did not understand your last message, I don't know from where you got this impression that we can't see it. What I replied in my last message was that we tried your solution of setting environment variable by using the command you sent which was;

    running the following command before starting Questa e.g.:

    export VCOM_STACK_SIZE=134217728

    Once again, we ran this command, and ran the Questa and tried compiling a model, but still were getting the same error.

    I am saying that if you are using compute machine with administrator, you probably need to check this with admin IT as the message is saying, I view this an IT issue rather than FPGA


    Contact your system administrator to set the hard limit above this value
