QL-1 he Following designs contain the errors made in VHDL. What are they? lib ary ieee ; use ieee.std_logic-1164.all; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE STD_LOGIC_UNSIGNED.ALL; entity shift_reg is port ( I: in std_logic: clock: in std_logic; shift: in std_logic; Q: out std_logic); end shift_rej; architecture behv of shift_reg is - initialize the declared signal signal S: std_iogic_vector(2 downto 0):= " 11111"; prosess(1, ftock, sini:t, s) begin II everything happens upon the clock changing if clock'event and clock=' 1 ' then if shift = ' 1 ' then S
