Hi Mayur,
Actually, I used “*” as the visibility for the set method. This is what I did in the build_phase() of my base_test:
uvm_config_db#(testbench_env_config)::set(this, "*", "cfg", cfg);
From my understanding, the visibility of “cfg” is “test_h.*”, which means it is visible everywhere. (Correct me if I’m wrong).
Another thing is, if the problem is in the visibility, then even if I use env.agt.sqr instead of null, uvm_fatal should have flagged too… But it didn’t. Therefore, my guess is there might be some connection with the use of a null sequencer and it somehow alters the set visibility… I’m guessing this could be a bug in the UVM itself. I don’t know.
