Question about uvm_config_db of SV interface

Hi,

I have a question when I use uvm_config_db for interface connection.

Generally, I know we use set() and get() function of "uvm_config_db" when we connect interface instance with virtual interface.

As I know, uvm_config_db#(virtual aaa_intf)::set() is described inside top testbench module.

And uvm_config_db#(virtual aaa_intf)::get() is some phase of inside class.

What I want to do is to move set() function into some phase of class.

Is it possible?

If possible, which phase can I use not to be no problem in topology?

Could you give me an example?

I generally descirbes uvm_config_db#(virtual aaa_intf)::get() in connect_phase.

Thanks & Regards,

YYN
