uvm_resource_db confusion

[shanghai1943]

Hi friends,

May I ask you:

1, what's the difference between uvm_config_db and uvm_resource_db ?

2,  in what situation should I use uvm_resource_db ?

3, can uvm_resource_db#(type)::get_by_name()/get_by_type() work? I've tried but seemed not to work.

Thanks

1. uvm_resource_db is a datbase which is used as basis for uvm_config_db. uvm_config_db is adding more flexibility to uvm_resource_db.

2. You should never use uvm_resource_db

3. Is obsolete because of 2.

uvm_config_db is simply a facade pattern on top of the uvm_resource_db. As mentioned above, most recommend avoiding direct use of the resource db because the config db adds more consistency to its use.
