Create a new architecture for ripple_counter (below) called beh_mod10cnt that changes the behavior to a modulo-10 ripple counter.
The ripple counter entity
entity ripple_counter is generic (n : natural := 4); port ( clk : in std_logic; clear : in std_logic; dout : out std_logic_vector(n-1 downto 0) ); end ripple_counter;
The ripple counter architecture
architecture arch_rtl of ripple_counter is signal clk_i : std_logic_vector(n-1 downto 0); signal q_i : std_logic_vector(n-1 downto 0); begin clk_i(0) <= clk; clk_i(n-1 downto 1) <= q_i(n-2 downto 0); gen_cnt: for i in 0 to n-1 generate dff: process(clear, clk_i) begin if (clear = '1') then q_i(i) <= '1'; elsif (clk_i(i)'event and clk_i(i) = '1') then q_i(i) <= not q_i(i); end if; end process dff; end generate; dout <= not q_i; end arch_rtl;
