使用Verilog语言分别编写一个程序和其测试程序要求如下1、某赛事共有10名评委组成评委组,具有评分权限;另有1名记分员,只进行主持和记分显示;评委全部表决评分后,只有记分员按下计分按钮则总的评分才会显示在8位数码管上; 2、评委1是组长,如果该组长不同意,则8位数码管上只显示- - - - - - - -(即显示8条横杠); 3、只有评委1(组长)投票同意后,才会将所有评委的评分进行累加,并显示在8位数码管上; 4、评委1(组长)投票记10分;评委2和评委3是两名副组长,投票记8分;其他人都是普通评委,投票记5分; 5、编写testbench仿真文件,通过波形仿真来验证正确性

好的,我可以提供一个Verilog语言的程序和相应的测试程序,实现上述要求:
```
// 定义模块
module evaluation_system(
input wire clk, // 时钟信号
input wire rst, // 复位信号
input wire agree, // 同意信号
input wire [9:0] scores, // 评委评分
output wire [7:0] display // 显示评分
);
// 定义内部信号
reg [31:0] total_score; // 总分
reg [7:0] final_score; // 最终评分
reg [3:0] agree_count; // 同意票数
reg [7:0] display_score; // 显示评分
reg [1:0] leader_score; // 领导评分
// 评分规则
parameter NORMAL_SCORE = 5;
parameter VICE_LEADER_SCORE = 8;
parameter LEADER_SCORE = 10;
// 初始化
initial begin
total_score = 0;
final_score = 0;
agree_count = 0;
display_score = 0;
leader_score = 0;
end
// 复位逻辑
always @(posedge rst) begin
total_score <= 0;
final_score <= 0;
agree_count <= 0;
display_score <= 0;
leader_score <= 0;
end
// 计算总分
always @(posedge clk) begin
if (agree) begin
total_score <= total_score + scores;
if (scores[0] == 1) begin
leader_score <= LEADER_SCORE;
end else if (scores[1] == 1 || scores[2] == 1) begin
leader_score <= VICE_LEADER_SCORE;
end else begin
leader_score <= NORMAL_SCORE;
end
end
end
// 统计同意票数
always @(posedge clk) begin
if (agree) begin
agree_count <= agree_count + 1;
end
end
// 计算最终评分
always @(posedge clk) begin
if (agree_count == 10) begin
if (scores[0] == 0) begin
final_score <= 0;
end else begin
final_score <= total_score + leader_score;
end
end
end
// 显示评分
always @(posedge clk) begin
display_score <= final_score;
end
// 连接显示器
assign display = display_score;
endmodule
```
接下来是测试程序:
```
// 定义测试程序
module evaluation_system_tb;
// 定义内部信号
reg clk;
reg rst;
reg agree;
reg [9:0] scores;
wire [7:0] display;
// 实例化被测模块
evaluation_system dut (
.clk(clk),
.rst(rst),
.agree(agree),
.scores(scores),
.display(display)
);
// 初始化
initial begin
clk = 0;
rst = 1;
agree = 0;
scores = 0;
#10 rst = 0;
end
// 时钟信号
always #5 clk = ~clk;
// 测试用例1:评委1不同意
initial begin
#15 scores = 10'b0000000000;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 agree = 1;
#5 agree = 0;
#5 $display("Test Case 1: %d", display);
#5 assert(display == 8'b11111111) else $error("Test Case 1 failed!");
#5 $finish;
end
// 测试用例2:评委1同意
initial begin
#15 scores = 10'b0000000001;
#5 agree = 1;
#5 scores = 10'b0000001000;
#5 agree = 1;
#5 scores = 10'b0000001000;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 scores = 10'b0000010101;
#5 agree = 1;
#5 $display("Test Case 2: %d", display);
#5 assert(display == 8'b00010101) else $error("Test Case 2 failed!");
#5 $finish;
end
endmodule
```
以上是一个简单的评分系统的Verilog程序和测试程序,可以通过仿真来验证其正确性和稳定性。
