Question

Please no handwriting

Start a new Quartus project for J-K flip-flop active low

type the VHDL code

create the circuits in Quartus.

Answer 1

VHDL code fro JK Flip FLop

library ieee;

use ieee. std_logic_1164.all;

use ieee. std_logic_arith.all;

use ieee. std_logic_unsigned.all;

entity JK_FF is

PORT( J,K,CLOCK: in std_logic;

Q, QB: out std_logic);

end JK_FF;

Architecture behavioral of JK_FF is

begin

PROCESS(CLOCK)

variable TMP: std_logic;

begin

if(CLOCK='1' and CLOCK'EVENT) then

if(J='0' and K='0')then

TMP:=TMP;

elsif(J='1' and K='1')then

TMP:=not TMP;

elsif(J='0' and K='1')then

TMP:='1';

else

TMP:='0';

end if;

end if;

Q<=TMP;

QB <=not TMP;

end PROCESS;

end behavioral;
