Fynjy0 [20]

Answer and Explanation:

--        Here we define the AND gate that we need for

-- the Half Adder

library ieee;

use ieee.std_logic_1164.all;

entity andGate is        

  port( A, B : in std_logic;

           F : out std_logic);

end andGate;

architecture func of andGate is

begin

  F <= A and B;

end func;

--        Here we define the XOR gate that we need for

-- the Half Adder

library ieee;

use ieee.std_logic_1164.all;

entity xorGate is

  port( A, B : in std_logic;

           F : out std_logic);

end xorGate;

architecture func of xorGate is

begin

  F <= A xor B;

end func;

-- At this point we construct the half adder using

-- the AND and XOR gates

library ieee;

use ieee.std_logic_1164.all;

entity halfAdder is

  port( A, B : in std_logic;

   sum, Cout : out std_logic);

end halfAdder;

architecture halfAdder of halfAdder is

component andGate is -- import AND Gate

     port( A, B : in std_logic;

              F : out std_logic);

  end component;

component xorGate is -- import XOR Gate

    port( A, B : in std_logic;

             F : out std_logic);

  end component;

begin

G1 : xorGate port map(A, B, sum);

G2 : andGate port map(A, B, Cout);

end halfAdder;

---------------------------------------------------------END

---------------------------------------------------------END

Test Bench:

--import std_logic from the IEEE library

library ieee;

use ieee.std_logic_1164.all;

entity halfAdder_tb is

end halfAdder_tb;

architecture tb of halfAdder_tb is

component halfAdder is

    port( A, B : in std_logic;

      sum, Cout : out std_logic);

  end component;

signal A, B, sum, Cout: std_logic;

begin

  mapping: halfAdder port map(A, B, sum, Cout);

  process

  variable errCnt : integer := 0;

  begin

--TEST 1

  A <= '0';

    B <= '1';

    wait for 10 ns;

    assert(sum = '1') report "sum error 1" severity error;

    assert(Cout = '0') report "Cout error 1" severity error;

    if(sum /= '1' or Cout /= '0') then

       errCnt := errCnt + 1;

    end if;

--TEST 2

  A <= '1';

    B <= '1';

    wait for 10 ns;

    assert(sum = '0') report "sum error 2" severity error;

    assert(Cout = '1') report "Cout error 2" severity error;

    if(sum /= '0' or Cout /= '1') then

       errCnt := errCnt + 1;

    end if;

--TEST 3

  A <= '1';

    B <= '0';

    wait for 10 ns;

    assert(sum = '1') report "sum error 3" severity error;

    assert(Cout = '0') report "Cout error 3" severity error;

    if(sum /= '1' or Cout /= '0') then

        errCnt := errCnt + 1;

    end if;

---- SUMMARY ----

    if(errCnt = 0) then

      assert false report "Success!" severity note;

    else

       assert false report "Faillure!" severity note;

    end if;

end process;

end tb;

-------------------------------------------------------------

configuration cfg_tb of halfAdder_tb is

  for tb

  end for;

end cfg_tb;
