DSim Desktop Local Tool Installations - Failed to get list of versions

red_elephant

I have never used DSim before. I created a student account. I installed the extension for the Desktop version in VS Code and logged in to my account following the instructions, but when I try to install DSim I get the error in the screenshot. What should I do?

Thank you.

You should install DSim Studio and then DSim from there. DSim Desktop is being deprecated. See this support article for details:

I was able to download DSim Studio and run it with the hello.sv example, thank you. But when I try to run it with Altair's uvm-hello-world-main example I get the following error at the end of Elab1:

I have the same elaboration error only when I use DSim with UVM on Windows. It looks the default DSim Studio installation directory of Windows version is problematic for UVM compile.

C:\Program Files\Altair\DSim\

I tried the Linux version of DSim Studio via WSL (Ubuntu-24.04) on Windows 11. Elaboration and simulation completed without errors but I cannot see the wave file.

I am completely new to UVM and I don't know if a wave file should be generated. This is the simulation result:

This is expected behaviour. Waveforms and waveform files are generated only if the design's simulation options specify them, whether the design is UVM or not. This example design does not specify them, as can be seen in the Options of the Elab and Sim configurations.

See https://help.metrics.ca/support/solutions/articles/154000141124-how-to-enable-waveform-dumping for details.

The UVM error is a known limitation for Windows machines:

This limitation will be removed in the next release of DSim.
