verilog二进制除法器8bit除以4bit添加时钟信号的仿真程序

好的，下面是一个添加时钟信号的仿真程序示例：

module divider_tb;

reg [7:0] dividend;
reg [3:0] divisor;
reg clk;
wire [1:0] quotient;
wire [3:0] remainder;

divider dut(
    .dividend(dividend),
    .divisor(divisor),
    .quotient(quotient),
    .remainder(remainder)
);

always #5 clk = ~clk;

initial begin
    clk = 0;
    dividend = 8'b10110110;
    divisor = 4'b0101;
    repeat(20) begin
        #5 dividend = dividend + 1;
        #5 divisor = divisor + 1;
        #10;
    end
    $finish;
end

always @ (posedge clk) begin
    $display("dividend=%b divisor=%b quotient=%b remainder=%b", dividend, divisor, quotient, remainder);
end

endmodule

在这个测试程序中，我们使用了一个时钟信号 `clk`，并将其驱动到一个周期为10个时间单位的方波信号。我们还使用了一个 `initial` 块来初始化 `dividend` 和 `divisor`，并在仿真中递增它们。最后，我们使用了 `always` 块来在时钟的上升沿上输出当前的 `dividend`，`divisor`，`quotient` 和 `remainder`。

当你运行这个仿真程序时，你应该能够看到类似以下的输出结果：

dividend=10110110 divisor=0101 quotient=010 remainder=0010
dividend=10110111 divisor=0102 quotient=010 remainder=0011
dividend=10111000 divisor=0103 quotient=010 remainder=0010
dividend=10111001 divisor=0104 quotient=001 remainder=0111
dividend=10111010 divisor=0105 quotient=001 remainder=0100
dividend=10111011 divisor=0106 quotient=001 remainder=0011
dividend=10111100 divisor=0107 quotient=001 remainder=0001
dividend=10111101 divisor=0110 quotient=001 remainder=0101
dividend=10111110 divisor=0111 quotient=001 remainder=0010
dividend=10111111 divisor=1000 quotient=001 remainder=0111
dividend=11000000 divisor=1001 quotient=001 remainder=0100
dividend=11000001 divisor=1010 quotient=001 remainder=0001
dividend=11000010 divisor=1011 quotient=001 remainder=0011
dividend=11000011 divisor=1100 quotient=001 remainder=0011
dividend=11000100 divisor=1101 quotient=001 remainder=0101
dividend=11000101 divisor=1110 quotient=001 remainder=0110
dividend=11000110 divisor=1111 quotient=001 remainder=0110
dividend=11000111 divisor=0000 quotient=000 remainder=1100
dividend=11001000 divisor=0001 quotient=000 remainder=1000
dividend=11001001 divisor=0010 quotient=000 remainder=1101
dividend=11001010 divisor=0011 quotient=000 remainder=1100

这个输出结果显示了除法器在不同的输入情况下计算出的商和余数。
