Honored Contributori want to know VHDL coding for digital alarm clock and also stopwatch because i need to submit final year project. my project of digital clock need to show on the LCD. Please help me ASAP. i perferred DE2 board.

library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_arith.all; use ieee.std_logic_unsigned.all; entity digi_clk is port (clk1 : in std_logic; seconds : out std_logic_vector(5 downto 0); minutes : out std_logic_vector(5 downto 0); hours : out std_logic_vector(4 downto 0) ); end digi_clk; architecture Behavioral of digi_clk is signal sec,min,hour : integer range 0 to 60 :=0; signal count : integer :=1; signal clk : std_logic :='0'; begin seconds <= conv_std_logic_vector(sec,6); minutes <= conv_std_logic_vector(min,6); hours <= conv_std_logic_vector(hour,5); --clk generation.For 100 MHz clock this generates 1 Hz clock. process(clk1) begin if(clk1'event and clk1='1') then count <=count+1; if(count = 50000000) then clk <= not clk; count <=1; end if; end if; end process; process(clk) --period of clk is 1 second. begin if(clk'event and clk='1') then sec <= sec+ 1; if(sec = 59) then sec<=0; min <= min + 1; if(min = 59) then hour <= hour + 1; min <= 0; if(hour = 23) then hour <= 0; end if; end if; end if; end if; end process; end Behavioral;Honored ContributorSuper thx my teacher :) is that for de2 board? Time show in LCD? Include alarm system?
