Half Adder (Behavioral Style)
The Half Adder circuit in Digital Electronics is used to add two 1-bit numbers and the circuit generates Sum and Carry as the outputs of this operation. VHDL Code: library IEEE; use IEEE.STD_LOGIC_1164.ALL; entity HA_behav is Port ( A,B : in STD_LOGIC; Sum,Carry : out STD_LOGIC); end HA_behav; architecture Behavioral of HA_behav is begin process(A,B) begin if(A='0' and B='0') then Sum <= '0'; Carry <= '0'; elsif(A='1' and B='1') then Sum <= '0'; Carry <= '1'; else Sum <= '1'; Carry <= '0'; end if; end process; end Behavioral; Testbench: LIBRARY ieee; USE ieee.std_logic_1164.ALL; ENTITY HA_behav_tb IS END HA_behav_tb; ARCHITECTURE behavior OF HA_behav_tb IS COMPONENT HA_behav PORT( A : IN std_logic; B : IN std_logic; ...
