VHDL code for SR Flip Flop

library ieee;
use ieee.std_logic_1164.all;

entity bejoy_rsff is
port(s,r,clk:in std_logic;q,q1,z:inout std_logic);
end bejoy_rsff;

architecture arc of bejoy_rsff is
begin
process(clk)
begin

if clk='1' then
z<=s or ((not r) and q);
q<=z after 5ns;
q1<=not z after 5ns;

end if;
end process;
end arc;

  1. Helped me a lot in lab!! Thank you :)

  2. very nice but you should have written it in terms of edge trigger and not the level trigger.For detecting EDGE the construst is rising_edge(clk).

    BTW nice work
