VHDL code for AND gate using Behavioral model

What is AND Gate?

It is a logical gate in which if any input is zero(reset) then output will become zero(reset)

VHDL code for and gate using Behavioral modeling:

entity AND_1_BEV is Port ( A : in STD_LOGIC; B : in STD_LOGIC; C : out STD_LOGIC); end AND_1_BEV; architecture Behavioral of AND_1_BEV is begin process (A, B) begin if(A='1' and B='1') then C <= '1'; else C <= '0'; end if; end process; end Behavioral;

Simulation code for and gate using dataflow modeling:

o know the performance and output of an entity made by the VHDL Programming language, we have to add one more VHDL code file (called simulation code or testbench file).VHDL simulation code for and gate using dataflow modeling is given bellow-

entity AND_1_BEV_TB is end AND_1_BEV_TB; architecture Behavioral of AND_1_BEV_TB is component AND_1_BEV is Port ( A : in STD_LOGIC; B : in STD_LOGIC; C : out STD_LOGIC); end component; signal A : STD_LOGIC := '0'; signal B : STD_LOGIC := '0'; signal C : STD_LOGIC; begin uut: AND_1_BEV port map ( A => A, B => B, C => C ); stim_proc: process begin wait for 100ns; B <= '1'; wait for 100ns; A <= '1'; B <= '0'; wait for 100ns; B <= '1'; wait; end process; end Behavioral;

WaveForm of AND Gate:

                                                               
 When VHDL simulation code for and gate using dataflow modeling get executed successfully then you can have a waveform which will have all input-output port name. this waveform will display output of all possible cases of input as given bellow-
