你能说一个具体代码吗

好的，我可以给你一个简单的Verilog HDL代码，实现上述功能：

module scoreboard(
  input clk,
  input rst,
  input [2:0] yellow_score_in,
  input [2:0] red_score_in,
  input btn1,
  input btn2,
  input btn3,
  output reg [6:0] yellow_led,
  output reg [6:0] red_led,
  output reg [6:0] yellow_score_out,
  output reg [6:0] red_score_out
);

reg [2:0] yellow_score;
reg [2:0] red_score;

always @(posedge clk) begin
  if (rst) begin
    yellow_score <= 3'd0;
    red_score <= 3'd0;
  end else begin
    if (btn1) begin
      yellow_score <= yellow_score + 3'd1;
      yellow_led <= 7'b1000000;
    end else if (btn2) begin
      yellow_score <= yellow_score + 3'd2;
      yellow_led <= 7'b1000000;
    end else if (btn3) begin
      yellow_score <= yellow_score + 3'd3;
      yellow_led <= 7'b1000000;
    end else begin
      yellow_led <= 7'b0000000;
    end
    
    if (btn4) begin
      red_score <= red_score + 3'd1;
      red_led <= 7'b1000000;
    end else if (btn5) begin
      red_score <= red_score + 3'd2;
      red_led <= 7'b1000000;
    end else if (btn6) begin
      red_score <= red_score + 3'd3;
      red_led <= 7'b1000000;
    end else begin
      red_led <= 7'b0000000;
    end
  end
end

assign yellow_score_out = {7'b0000000, yellow_score};
assign red_score_out = {red_score, 7'b0000000};

endmodule

这个代码实现了计分器的基本功能，包括计数器、七段数码管、按键输入和LED输出。在这个例子中，我们使用三个按钮来表示黄队得分，另外三个按钮来表示红队得分。当按下对应的按钮时，计数器中对应的分数将增加，并且对应的LED灯也会亮起来。同时，我们使用了两个七段数码管来显示黄队分数和红队分数。
