十二进制计数器vivado代码及仿真程序

十二进制计数器vivado代码及仿真程序,该怎么做不会,找的很多都是其他软件的不知道vivado该怎么做

该回答通过自己思路及引用到GPTᴼᴾᴱᴺᴬᴵ搜索,得到内容具体如下:
在 Vivado 中实现一个十二进制计数器,可以通过以下步骤完成:

1、创建一个新的 Vivado 工程,并在 Block Design 中添加一个 Clock Wizard IP 核和一个自定义的计数器模块。

2、 配置 Clock Wizard IP 核,设置时钟频率和时钟输出。

3、 创建一个新的 VHDL 文件,命名为 counter_12.vhd

4、 在 counter_12.vhd 文件中,定义一个带有一个时钟输入 clk 和一个输出 count 的计数器模块。

-- counter_12.vhd

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;

entity counter_12 is
    Port ( clk : in  STD_LOGIC;
           count : out  STD_LOGIC_VECTOR (3 downto 0));
end counter_12;

architecture Behavioral of counter_12 is
    signal counter : integer range 0 to 11 := 0;
begin
    process(clk)
    begin
        if rising_edge(clk) then
            if counter = 11 then
                counter <= 0;
            else
                counter <= counter + 1;
            end if;
        end if;
    end process;

    count <= std_logic_vector(to_unsigned(counter, 4));
end Behavioral;

5、 在 Block Design 中添加一个 Custom IP 核,将 counter_12.vhd 文件作为源文件导入。

6、 链接 Custom IP 核和 Clock Wizard IP 核,并为 Custom IP 核分配一个 AXI GPIO 接口。

7、 在设计中生成一个 bitstream 文件,并将其加载到 FPGA 中。

8、 在 Vivado 中打开仿真窗口,创建一个新的仿真文件,命名为 counter_12_tb.vhd

9、 在 counter_12_tb.vhd 文件中,定义一个仿真模块,并为模块添加一个时钟输入 clk 和一个输出 count

-- counter_12_tb.vhd

library ieee;
use ieee.std_logic_1164.all;

entity counter_12_tb is
end counter_12_tb;

architecture behavior of counter_12_tb is
    signal clk : std_logic := '0';
    signal count : std_logic_vector(3 downto 0) := (others => '0');
begin
    uut: entity work.counter_12
        port map (
            clk => clk,
            count => count
        );

    clk_process :process
    begin
        wait for 10 ns;
        clk <= not clk;
    end process;

end behavior;

10、 在 counter_12_tb.vhd 文件中,添加一个仿真模块的测试过程,并为仿真模块的输入输出信号创建波形。

-- counter_12_tb.vhd

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

entity counter_12_tb is
end counter_12_tb;

architecture behavior of counter_12_tb is
    signal clk : std_logic := '0';
    signal count : std_logic_vector(3 downto 0) := (others => '0');
begin
    uut: entity work.counter_12
        port map (
            clk => clk,
            count => count
        );

    clk_process :process
    begin
        wait for 10 ns;
        clk <= not clk;
    end process;

    testbench : process
    begin
        wait for 100 ns;
        assert (count = "0000") report "Test case 1 failed" severity error;

        wait for 100 ns;
        assert (count = "0001") report "Test case 2 failed" severity error;

        wait for 100 ns;
        assert (count = "0002") report "Test case 3 failed" severity error;

        wait for 100 ns;
        assert (count = "0003") report "Test case 4 failed" severity error;

        wait for 100 ns;
        assert (count = "0004") report "Test case 5 failed" severity error;

        wait for 100 ns;
        assert (count = "0005") report "Test case 6 failed" severity error;

        wait for 100 ns;
        assert (count = "0006") report "Test case 7 failed" severity error;

        wait for 100 ns;
        assert (count = "0007") report "Test case 8 failed" severity error;

        wait for 100 ns;
        assert (count = "0008") report "Test case 9 failed"severity error;

        wait for 100 ns;
        assert (count = "0009") report "Test case 10 failed" severity error;

        wait for 100 ns;
        assert (count = "000A") report "Test case 11 failed" severity error;

        wait for 100 ns;
        assert (count = "000B") report "Test case 12 failed" severity error;

        wait;
    end process;

end behavior;

11、 在 Vivado 中运行仿真,确保计数器模块按照预期工作。

以上是一个实现十二进制计数器的基本步骤,您可以根据自己的需求进行调整。注意,在步骤 4 中,我们使用了一个 std_logic_vector 类型的输出端口 count,它代表了十二进制计数器的输出值,其范围为 0-11。在步骤 9 中,我们为测试模块添加了一些测试用例以确保计数器功能正确。
