uvm_resource_db/uvm_config_db usage

[antwens]

UVM agents use uvm_resource_db/uvm_config_db to configure components. what is the difference between these two?..

how does the below code work,

 

uvm_resource_db # (virtual bus_if.monitor)::read_by_name("interfaces", bus_if_monitor", m_env.m_bus_mon.mi)

 

uvm_config_db#(int)::set(this, "env.*","m_reg_state", venv::START)

hi,

 

uvm_resource_db is a layer under uvm_config_db. uvm_config_db provides a simpler and clearer api compatible with the traditional set_config_xyz() methods. for normal purposes uvm_config_db is the best route.
