Design and verify full subtractor by using behavioural model with if,elsif& then statements.

FULL SUBTRACTOR


AIM:


Design and verify full subtractor by using behavioural model with if,elsif& then statements.


PROGRAM:


library ieee;
use ieee.std_logic_1164.all;
entity f ullsub is
port(a:in std_logic_vector(2 downto 0);
d,b:out std_logic);
end fullsub;
architecture fullsub of fullsub is
begin
process(a)
begin
if a="000" then d<='0';b<='0'; elsif a="001" then d<='1';b<='1'; elsif a="010" then d<='1';b<='1'; elsif a="011" then d<='0';b<='1'; elsif a="100" then d<='1';b<='0'; elsif a="101" then d<='0';b<='0'; elsif a="110" then d<='0';b<='0'; else d<='1';b<='1'; end if; end process; end fullsub; 


 SIMULATION OUTPUT:







RESULT: Full adder is simulated and verified
