Modelsim ASE starter not directly support UVM

Hi Guys, I installed modelsim ASE starter edition 2021.02.

From common knowledge, I thought this tool has pre-compiled UVM features. But after I installed, I found `include "uvm_macros.svh" cannot be compiled. Then I checked library, no UVM related libs.

Did I missed some steps?

    Hi,


    Unfortunately ModelSim does not have pre-compiled UVM features. You are probably thinking of Questa Sim.


    You need to download UVM source files, you can do that here: https://www.accellera.org/downloads/standards/uvm


    And you'll need to compile the uvm_pkg as well.


    vlog -work work -sv -stats=none C:/work/ST/simulation/tb_captur_1.sv <uvm_pkg path>/uvm_pkg.sv +incdir+<UVM source path>/src


    Regards,

    Nurina

      Hi Nurina

      Thank you for your help, now the compilation can be proceed, and the tb module appears in work lib. Information shows below:

      vlog -work work -sv -stats=none C:/work/ST/simulation/tb_capture_1.sv C:/intelFPGA_pro/21.1/modelsim_ase/uvm_lib/src/uvm_pkg.sv +incdir+C:/intelFPGA_pro/21.1/modelsim_ase/uvm_lib/src/
      # Model Technology ModelSim - Intel FPGA Edition vlog 2021.1 Compiler 2021.02 Feb 3 2021
      # -- Compiling package tb_capture_1_sv_unit
      # -- Importing package uvm_pkg
      # -- Compiling module tb_capture_1
      # -- Compiling package uvm_pkg
      #
      # Top level modules:
      # tb_capture_1

      But when I load the "tb_capture_1", error happens:

      vsim work.tb_capture_1
      # vsim work.tb_capture_1
      # Start time: 16:32:57 on Jun 10,2021

      #
      # FATAL ERROR while loading design
      # Error loading design

      Should I also install other software?

    Hi,


    The Fatal Error occurs when the module for gcc compilation is insufficient. Can you go to the installation folder of ModelSim and confirm if gcc-4.2.1-mingw32vc12 exists? Let me know if it has a different name like vc9.


    Once confirmed the correct gcc folder exists, check that the path of the C compiler in correctly set in environment variable path:

    1. Open Environment Variables. To do this, go to Control Panel->System & Security->System->Advanced system settings->Environment Variables...
    2. Under User Variables, go to "Path" and click "Edit"
    3. Check that it has the following path included: <modelsim installation path>\modelsim_ase\win32aloem
    4. If path not included, click "New" and enter the mentioned path.


    Please let me know the results.

    Nurina

      Hi Nurina,

      The environment variable exists, and gcc folder also exists, you can see in attached screen shots:

      Hi Nurina

      I will try to downgrade my version, then tell you the result later. Thanks.

    Hi,

    I used your previous method of saving the UVM source files in uvm_lib folder and it worked. As long as you specify the path of the uvm library on ModelSim then it should be fine.

    I believe your installation type should be fine, as long as you have the DPI tool installed (gcc-4.2.1-mingw32vc12).

    Could you try to using the following source code? That one worked for me. https://www.accellera.org/downloads/standards/uvm

      Hi Nurina

      Good news! I found Starter Edition 20.1 can run with original UVM src (installed with modelsim). This morning I ran a wrong shortcut after a modelsim crash, I'm sorry.

      Now with version 20.1, both original installed UVM src or separated downloaded source code (you suggested), can run successfully.

      I will use the earlier 20.1 for current job, thanks.

      I think I already have "accept as solution" for the original question, so it will be fine?

    Hi,


    Can you attach your .qar file so I can reproduce this error?


    Thanks,

      Hi Nurina

      I'm not simulate it in quartus environment. I directly build a modelsim project, and the rtl is quite simple. You can check this in attach file.

    Hi,


    Can you let me know which UVM library you used?


    Thanks,

    Hi,

    Actually it's alright. I couldn't seem to unzip the .tar.gz properly earlier and now I can. Again, I'll let you know what engineering comes back with.

    Hi,


    I don't have any feedback from engineering at the moment. Can you try this with ModelSim AE instead though?

      Hi Nurina

      Our company doesn't have Modelsim license. I can try this starter edition in my personal PC later. Thank you all the same.

      Hi Nurina

      Sorry for late response, I just back from vacation.

      I tried v20.1 in another server, but the result is the same:

      #
      # Top level modules:
      # tb_capture_1
      # vsim -c tb_capture_1 -voptargs=""+acc=r""
      # Start time: 10:47:37 on Jul 13,2021
      # ** Fatal: (vsim-7019) Can't locate a C/C++ compiler for 'DPI Export Compilation'.
      #
      # FATAL ERROR while loading design
      # Error loading design
      # Error: Error loading design

      I already set the environment variable in that server, and use same command parameters.

      Since the problem is already different from original question, I think you might close this question, and I may do some experiment in different tools. Thanks for so much helps!

    Hi,

    Maybe you downloaded the wrong UVM source file? It's odd that you're seeing this error because our internal team has fixed this error in Quartus v17.0.

    OK I shall close this thread. I’m glad that your original question has been addressed, I now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.

      Hi Nurina

      I use the UVM src together with the modelsim installation. I think it should has best compatibility.

      You mentioned the error has been fixed in Quartus. My installation of elder version 20.1, only include modelsim starter edition, no Quatus 20.1 installed. Would this installation type runs well?
