Hello seniors please let me know about this fatal error,
UVM_FATAL verilog_src/uvm-1.1d/src/base/uvm_component.svh(1744) @ 0: fifo_wr[0] [CLDEXT] Name ‘fifo_wr[0]’ is not unique to other top-level instances. If parent is a module, build a unique name by combining the the module name and component name: $sformatf(“%m.%s”,“fifo_wr[0]”).
In reply to uvm_verification:
I’m recpmmending 2 things in the given order:
(1) read the error message
(2) post a piece of code related to the error message.
On each hierarchy level the instance names have to be unique. You are violating this rule.
Because you do not show any code I cannot give a deeper advice.

everything i post : SET in w_agent_top and GET in w_agent,
please check sir.

I’d like to see the file w_config.sv. It is not there.
sir in both w_agent_top & w_agent have:- `include"w_config.sv"
