给以下Verilog代码写一段quartusii 的miaobiao_vlg_tst测试代码module miaobiao(clk,clr,push,sel,a_g); input clk,clr,push; output[2:0]sel; output[6:0]a_g; wire push1,fdiv_10,clr1,cin2,cin4,cin6; wire[3:0]bcd1,bcd2,bcd3,bcd4,bcd5,bcd6,bcd7,bcd8; switch switchpush(clk,push,push1); switch switchclr(clk,clr,clr1); fdiv10 fdiv(clk,push1,fdiv_10); count100 count100(fdiv_10,clr1,bcd1,bcd2,cin2); count60_1 count60_1(cin2,clr1,bcd3,bcd4,cin4); count60_2 count60_2(cin4,clr1,bcd5,bcd6,cin6); count24 count24(cin6,clr1,bcd7,bcd8); leds leds(clk,bcd1,bcd2,bcd3,bcd4,bcd5,bcd6,bcd7,bcd8,sel,a_g); endmodule

以下是针对该Verilog代码编写的测试代码：

module miaobiao_vlg_tst();

  // Inputs
  reg clk;
  reg clr;
  reg push;

  // Outputs
  wire [2:0] sel;
  wire [6:0] a_g;

  // Instantiate the Unit Under Test (UUT)
  miaobiao uut (
    .clk(clk), 
    .clr(clr), 
    .push(push), 
    .sel(sel), 
    .a_g(a_g)
  );

  initial begin
    // Initialize Inputs
    clk = 0;
    clr = 0;
    push = 0;

    // Wait for 100 clock cycles to ensure initialization is complete
    #100;

    // Test case 1: Test that the counter counts up to 24 hours and wraps around
    for (int i = 0; i < 24*60*60; i++) begin
      // Toggle clock every cycle
      clk = ~clk;

      // Wait for combinational logic to settle
      #1;

      // Set push to 1 every 10 seconds to simulate seconds counter increment
      if (i % 10 == 0)
        push = 1;
      else
        push = 0;

      // Check outputs every clock cycle
      if (i % 60 == 0 && i < 24*60*60) begin
        // Check that the minutes counter is incrementing by 1 every minute
        if (a_g[3:0] != i/60 % 60)
          $error("Failed test case 1: Minutes counter not incrementing correctly");

        // Check that the hours counter is incrementing by 1 every hour
        if (a_g[6:4] != i/3600)
          $error("Failed test case 1: Hours counter not incrementing correctly");
      }
    end

    // Test case 2: Test that the clear signal resets all counters to 0
    clr = 1;
    #10;
    clr = 0;
    for (int i = 0; i < 60; i++) begin
      // Toggle clock every cycle
      clk = ~clk;

      // Wait for combinational logic to settle
      #1;

      // Check outputs every clock cycle
      if (i == 0) begin
        // Check that all counters are reset to 0
        if (a_g != 7'b0000000)
          $error("Failed test case 2: Counters not reset to 0 after clear signal");
      }
    end

    $display("All test cases passed");
    $finish;
  end
endmodule

该测试代码包含两个测试用例：

1. 测试计数器是否能够准确地计算出24小时，并在达到24小时后重新开始计数。
2. 测试清除信号是否能够将所有计数器重置为0。
