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'.
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.
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
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.
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?
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.
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.
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.

Thank you John for this informative and easy to understand video on UVM!!
Awesome info... which is very useful for the beginners .. Thank a lot.. looking forward for more informative videos from you John .
Thank you for making UVM so interesting.
You can now run the UVM example shown in this video directly on www.edaplayground.com/x/Wzp

Superb John..!!
Thank u for this informative video
thank you it was very helpful
Thanks john
Thanks for this video.
Why do you need a my_env class? It does nothing.
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.
