Below is the modified code entity controller is Port ( reset : in STD_LOGIC; clk : in STD_LOGIC; ring_k_1 : in STD_LOGIC; b_n : in STD_LOGIC_vector(3 downto 0); start : in Does it analyze? So I added two signals which are: signal Din, Qout : std_logic_vector(7 downto 0); then set them as follows: Din=>D; Qout=>Q; But this still leaves me with Save your draft before refreshing this page.Submit any pending changes before refreshing this page.
