First Steps with UVM Part 1

[@miklosbence2582]

Terrific explanation! One thing: to avoid confusion you might want to draw attention to the fact that two different things are called here 'parents' - One parent of my_env is the base class uvm_env, the other parent of my_env is the my_test class that brought env to life. Unfortunately they are both called 'parents'.

You can now run the UVM example shown in this video directly on www.edaplayground.com/x/Wzp

[@miklosbence2582]

Hi, you have dut_if, dut_if1 ... Why not use postfixes like _it for 'interface type' and _ii for 'interface instance'? I think dut_ii and dut_it is much easier to follow. Just an oppinion.

Thank you John for this informative and easy to understand video on UVM!!

[@nagaprasadd6260]

Awesome info... which is very useful for the beginners .. Thank a lot.. looking forward for more informative videos from you John .

For new learners here, we have already imported the uvm package inside of my_pkg, yet when we import my_pkg in top module, we are again importing uvm_pkg eventhough it was imported in my_pkg itself. Why is that? Why not just import my_pkg and call it a day?

[@alexandrustireciu832]

Why isn't there any build_phase function for the test component? There is one for the environment component, but none for the test component. I am an absolute beginner with SV-UVM, so maybe this is a silly question. Thanks.

[@shivamrai2197]

Because build_phase is like "new" keyword in system verilog So you instantiate a subordinate class object in the parent class. Like wise environment is the child class of test, hence build_phase(or "new") is there for it. Hope you got the explaination.

Thank you for making UVM so interesting.

[@rameshahparameswaraiah6908]

Explains how a simple "Hello World" example can be implemented in UVM. You get understanding of UVM class based world and module based world of a typical UVM testbench and how they are connected. Good info on uvm_env class, uvm_test class and raising/dropping objections.

[@rameshahparameswaraiah6908]

Also has Information on : - where uvm environment object is created and how it is created - typical structure of uvm test class what all it should contain - registration of user defined uvm classes with uvm factory - how to call uvm test from uvm testbench top module

great video!

[@johnsmith2586]

Why do you need a my_env class? It does nothing.

[@SavageBits]

You don't need my_env for a super simple hello word example. However, you do need my_env for a real world uvm testbench, so it is included in this example for completeness. Check out the part 2 video in this series for better understanding.
