Contoh Program D Flip-Flop Pada VHDL

Sebuah contoh program vhdl dari D flip-flop edge triggered positif dengan asynchronous Reset:

library ieee;
use ieee.std_logic_1164.all;
entity DFF_RST is
port (CLK, RESET, D : in std_logic;
Q : out std_logic);
end DFF_RST;

architecture BEHAV_DFF of DFF_RST is
begin
DFF_PROCESS: process (CLK, RESET)
begin
if (RESET = ‘1’) then
Q <= ‘0’;
elsif (CLK’event and CLK = ‘1’) then
Q <= D;
end if;
end process;
end BEHAV_DFF;
