shine2828 Posted November 30, 2014 Report Share Posted November 30, 2014 Rsepected All, I found that there are many senior & well rich (by knowledge) engineers/ scientists exist over here in this forum. So I thought to take a chance to share my doubt in area of UVM as a student. I understand that I may not be even competant upto your level or you may find my doubt as silly. But your guidance & help is highly expected to my studies. A portion of code I have pasted below. Can anybody please guide me that what exactly this code means (especially run phase) ? I expect that senior/junior fellow in a group will justify my humble request. Thanks, Code : function void ram_scoreboard::memory_write(wr_xtn wd); if(wd.write) begin ref_data[wd.addr] = wd.data; end endfunction : memory_write //------- memory_read() method -------// function bit ram_scoreboard::memory_read(ref rd_xtn rd); if(rd.read) begin if(ref_data.exists(rd.addr)) begin rd.data = ref_data[rd.addr] ; return(1); end else begin return(0); end end endfunction : memory_read //----------------- run() phase -------------------// task ram_scoreboard::run_phase(uvm_phase phase); fork forever begin fifo_wrh.get(wr_data); memory_write(wr_data); end forever begin fifo_rdh.get(rd_data); check_data(rd_data); end join endtask //Explore method check_data function void ram_scoreboard::check_data(rd_xtn rd); rd_xtn ref_xtn; // Copy of read XTN $cast( ref_xtn, rd.clone()); if(mem_read(ref_xtn)) begin //compare if(rd.compare(ref_xtn)) begin `uvm_info(get_type_name(), $sformatf("Scoreboard - Data Match successful"), UVM_MEDIUM) end else `uvm_error(get_type_name(), $sformatf("\n Scoreboard Error [Data Mismatch]: \n Received Transaction:\n %s \n Expected Transaction: \n %s",rd.sprint(), ref_xtn.sprint())) end else uvm_report_info(get_type_name(), $psprintf("No Data written in the address=%d \n %s",rd.addr, rd.sprint())); endfunction Quote Link to comment Share on other sites More sharing options...
