VHDL Code for JK FlipFlop
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:='0';
else
TMP:='1';
end if;
end if;
Q<=TMP;
Q <=not TMP;
end PROCESS;
end behavioral;
