Hi @chr_sue, I have used fifos instead of queues. But the results are still the same, which I don’t understand why they are happening? I have given the scoreboard updated code with fifo’s addition.


task scoreboard::write_rec2(input seq_item tr);
 seq_item pkt = new();
 pkt.copy(tr);
 fifoRec2.try_put(pkt);
 $display("Queue Got this data: %0h",pkt.data);
endtask

task scoreboard::write_rec1(input seq_item tr);
 seq_item pkt = new();
 pkt.copy(tr);
 fifoRec1.try_put(pkt);
 $display("Queue Got this data: %0h",pkt.data);
endtask

task scoreboard::run_phase (uvm_phase phase);
  forever begin
     if (enb == 2'b11) begin
	fork 
		begin thread1(); end
		begin thread2(); end
	join
     end
     else if (enb == 2'b10) begin
	thread1();
     end
     else if (enb == 2'b01) begin
	thread2();
     end
  end
endtask

task scoreboard::thread2();
	fifo_Rec2.get(Rec2);
	fifo_Trans2.get(trans2);
	$display("Queue Received this Data: %0h", Rec2.data);
	compare(trans2.data,Rec2.data);  // this function two inputs and check equality
endtask

task scoreboard::thread1();
	fifo_Rec1.get(Rec1);
	fifo_Trans1.get(trans1);
	$display("Queue Received this Data: %0h", Rec1.data);
	compare(trans1.data,Rec1.data);  // this function two inputs and check equality
endtask

can you also give me some thought about this theory?
I have read somewhere in the blog due to some delay in the testbench environment’s components sometimes the scoreboard can’t process kinds of stuff and ends up being broken. Except for these very high-level thoughts, I haven’t seen much info about the theory. Can you please share some thoughts about this side too if you think that’s a possibility…?
