Develop a testbench for the Half Adder that verifies the structural model. The testbench will have no ports. Your testbench shou
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;

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;

Why is namibia one of the most sparsely populated countries in africa?
Vadim26 [7]
The reason for this is that part of Namibia is taken up by the Namib desert, and also elsewhere Namibia suffers a lack of water, and it is one of the driest places in Africa. In some areas of Namibia ground water is for example available only during some and not all months of the year.

What conclusion can you draw about life for Native Americans in New Spain? Explain your Answer
Ede4ka [16]

Answer:

They had a terrible life

Explanation:

The reason why the natives were reallocated to the new spain is because they lost the conflict against the soldiers of the Spanish empire. The spaniards took their land away from them and force them to move away.

Even after they're reallocated in new spain, they still subjected to a really rough treatment. They are forced to work in labor camps and forced to abandon the culture/tradition that they held throughout their life. The spanish Empire wanted them to  replace it with Spanish culture, language, and religion.
