二.PORT與IMP的代碼實例
2.1.A_PORT
class A extends uvm_component;
`uvm_component_utils(A)
uvm_blocking_put_port#(my_transaction) A_PORT;
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
A_PORT = new("A_PORT", this);
endfunction
virtual task main_phase(uvm_phase phase);
endtask
endclass2.2.B_IMP
class A extends uvm_component;
`uvm_component_utils(B)
uvm_blocking_put_imp#(my_transaction, B_IMP) B_IMP;
virtual function void build_phase(uvm_phase phase);
super.build_phase(phase);
B_IMP = new("B_IMP", this);
endfunction
virtual function void put(my_transaction tr);
`uvm_info("B", "Receive A Transaction", UVM_LOW)
tr.print();
endfunction : put
virtual task main_phase(uvm_phase phase);
endtask
endclass
