全加器仿真quartus源文件和测试文件

以下是全加器的VHDL源文件和测试文件的代码：

全加器的VHDL源文件（full_adder.vhd）：

library ieee;
use ieee.std_logic_1164.all;

entity full_adder is
    port (
        a, b, cin : in std_logic;
        sum, cout : out std_logic
    );
end full_adder;

architecture behavior of full_adder is
begin
    sum <= a xor b xor cin;
    cout <= (a and b) or (cin and (a xor b));
end behavior;

全加器的测试文件（full_adder_tb.vhd）：

library ieee;
use ieee.std_logic_1164.all;

entity full_adder_tb is
end full_adder_tb;

architecture behavior of full_adder_tb is
    component full_adder is
        port (
            a, b, cin : in std_logic;
            sum, cout : out std_logic
        );
    end component;

    signal a, b, cin, sum, cout : std_logic;

begin
    uut : full_adder port map (a => a, b => b, cin => cin, sum => sum, cout => cout);

    stim_proc : process
    begin
        a <= '0'; b <= '0'; cin <= '0'; wait for 10 ns;
        a <= '0'; b <= '0'; cin <= '1'; wait for 10 ns;
        a <= '0'; b <= '1'; cin <= '0'; wait for 10 ns;
        a <= '0'; b <= '1'; cin <= '1'; wait for 10 ns;
        a <= '1'; b <= '0'; cin <= '0'; wait for 10 ns;
        a <= '1'; b <= '0'; cin <= '1'; wait for 10 ns;
        a <= '1'; b <= '1'; cin <= '0'; wait for 10 ns;
        a <= '1'; b <= '1'; cin <= '1'; wait for 10 ns;
        wait;
    end process;

    result_proc : process
    begin
        wait for 80 ns;
        assert sum = '0' and cout = '0' report "Test failed for case 1" severity error;
        wait for 10 ns;
        assert sum = '1' and cout = '0' report "Test failed for case 2" severity error;
        wait for 10 ns;
        assert sum = '1' and cout = '0' report "Test failed for case 3" severity error;
        wait for 10 ns;
        assert sum = '0' and cout = '1' report "Test failed for case 4" severity error;
        wait for 10 ns;
        assert sum = '1' and cout = '0' report "Test failed for case 5" severity error;
        wait for 10 ns;
        assert sum = '0' and cout = '1' report "Test failed for case 6" severity error;
        wait for 10 ns;
        assert sum = '0' and cout = '1' report "Test failed for case 7" severity error;
        wait for 10 ns;
        assert sum = '1' and cout = '1' report "Test failed for case 8" severity error;
        wait;
    end process;
end behavior;

注意：要在Quartus中运行此仿真，请确保将这两个文件添加到Quartus项目中并进行仿真设置。
