dsim v2025. Can't find my test even though it's specified with +UVM_TESTNAME

Description: I created a testbench/env from scratch and all the files compile individually. The sim starts running but immediately ends with a fatal message saying the test can't be found because it's not registered with the factory (it is).

class test_001 extends base_test;

`uvm_component_utils(test_001)

…

Product/Topic Name :

dsim studio version 2025, configured to use uvm 1.2, running on Visual Studio Code on an Ubuntu 22.04.2 virtual machine (on a Mac Pro).

Related question: how do I do the equivalent of "make clean"? It looks like dsim is using files that aren't the latest (i.e. I fix or add something but the same errors show up), so I'd like to clean and try again.

Hi James,

Thanks for your interest in DSim. Did you follow the instructions for simulating UVM designs with DSim?

As for your question about the equivalent of "make clean", simply delete the directory "dsim_work" under your project directory to force DSim to compile/simulate from a clean slate rather than do incremental compilation.

I did follow the instructions, yes.All the other files compile, just not the test.

I'll try deleting the directory as well.

We'll need some more information. Where is test_001 defined? In a package? Inside a module? Inside the compilation-unit scope?

So I've tried two approaches. Listing each file, and using a manifest file and a package. Same result. The test file is listed in both cases and registered with the factory, so not sure why it can't be found.
