This is a clock divider code, just set the max-count value as per your requirenment. For ex. If I want 1Hz freq. set the max count to i/p freq value viz. 1sec = 1Hz Then, to get time period of 1sec i.e. 1 Hz frequency set max-count to 240000 as shown below: 1sec  =  24000000  -- for i/p frequency of 24 MHz. To get your desired frequency just calculate the maxcount with the formula given below: max_count = 24000000 * (1/your required frequency) CODE: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 library IEEE ; use IEEE.STD_LOGIC_1164.ALL ; use IEEE.numeric_std.all ; entity clk_div is Port ( Clk : in std_logic ; rst : in std_logic ; op : out std_logic ); end clk_div ; architecture behavioral of clk_div is constant max_count : natural := 24000000 ; -- I used 24MHz clock ...
