I am unable to generate the Cyclone VGX LPDDR2 controller IP due to an error.

I purchased a board with cyclone VGX and LPDDR2 installed.
I plan to use LPDDR2 hard memory controller and nios V with this cyclone Vgx.
However, when I generate the LPDDR2 controller with megawizerd,
an error occurs and I cannot generate the IP for the LPDDR2 controller.

The environment is Windows 11.
An error occurs in both Quartus Prime Standard 24.1 and 23.1.1_build993.
Please let me know the compatible environment.

    Hi Hidetaka,


    You can try to set the environment variable in your PC by adding the TBB_MALLOC_DISABLE_REPLACEMENT=1 parameter in System Variables.

    Then restart your PC.

    Try to replicate the issue again and share the generation log again.


    Regards,

    Adzim

      Hello Adzim-san,
      I added "TBB_MALLOC_DISABLE_REPLACEMENT=1" to the system environment variables you told me about, and was able to generate the Example Design without any errors.
      I'm very grateful to you.
      Please close this case here.

      Thanks, Hidetaka.

    Can you show your parameter settings and what the error is that you are seeing?

    Hi


    Can you share the IP generation window here?

    I want to observe the error message that you are facing.

      Hello, Adzim-san.
      sstrell-san.

      At first, I got the error: <./nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally>.
      After that, I successfully set up wsl1 and ubuntu-18.04 on Windows 11,
      and when I tried to generate LPDDR2 again, the following error message appeared.

      ////////

        Hello, Adzim-san.
        sstrell-san.

        When I saw the error message, the error was in the "Info: LPDDR2_top2: Generating example design" item,

        so I thought maybe I just shouldn't generate the example design, so I ran it, and it was generated without any errors.


        Error: Execution of script "/0008_LPDDR2_top2_gen/simulation/generate_sim_example_design.tcl" is causing an error, so I would appreciate it if you could fix this part.

        Regard, Hidetaka.
