LEDs in interleaving method

hi, i would like to thank all of you for helping me. i am now able to complete my project all thanks to you all guidance. below is the code is use for comparator 1 and comparator 2

comparator 1:

Library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_unsigned.all;

entity comparator is

port( q, b : in std_logic_vector( 6 downto 0);

c : out std_logic);

end comparator;

architecture body3 of comparator is

begin

process (q, b)

begin

if (q< b +1)

then c<='1';

else

c<='0';

end if;

end process;

end body3;

comparator 2:

Library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_unsigned.all;

entity comparator1 is

port( x, y : in std_logic_vector( 6 downto 0);

c1 : out std_logic);

end comparator1;

architecture body3 of comparator1 is

begin

process (x, y)

begin

if (x>19) and (x<= 20+y)

then c1<='1';

else

c1<='0';

end if;

end process;

end body3;
