Hi dave,
Error: (vlog-13069) C:/Users/AIR-NBH-1/Desktop/APB 3/apb_drv.sv(1): near “uvm_driver”: syntax error, unexpected IDENTIFIER.
** Error: C:/Users/AIR-NBH-1/Desktop/APB 3/apb_drv.sv(1): Error in class extension specification.
this the error in every component
Below is my driver component code:-
class apb_drv extends uvm_driver #(apb_seq_item);
`uvm_component_utils(apb_drv)
virtual apb_if vif;
apb_seq_item tx;
function new(string name=“”,uvm_component parent);
super.new(name,parent);
endfunction
function void build_phase(uvm_phase phase);
super.build_phase(phase);
tx = apb_seq_item::type_id::create(“tx”);
uvm_config_db#(virtual apb_if)::get(this,“”,“intf”,vif);
endfunction
task run_phase(uvm_phase phase);
forever
