entity ENC3 is

    Port ( Q : in std_logic;

           R : in std_logic;

           S : in std_logic;

           T : in std_logic;

           U : in std_logic;

           OUT0 : out std_logic;

           OUT1 : out std_logic;

           OUT2 : out std_logic;

           OUT3 : out std_logic);

end ENC3;

architecture Behavioral of ENC3 is

begin

            process (Q,R,S,T,U,V,W,X,Y,Z)

            begin

                        OUT0 <= R OR T OR V OR X OR Z;

                        OUT1 <= S OR T OR W OR X;

                        OUT2 <= U OR V OR W OR X;

                        OUT3 <= Y OR Z;

            end process;

end Behavioral;
