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。
