How to make an LED light by writing VHDL code program? i am just leanning VHDL.thank you !

It is very easy. Refer to below:  

 library IEEE; use IEEE.std_logic_1164.all;   Entity LED_light is   port ( LED_out : out std_logic); end LED_light;    Architechture RTL of LED_light is    begin     LED <= '1';   end RTL;

OFF (Stage1)>Dim (Stage2)>Full brightness (Stage3). I just need the logic, no need to type the full code here. Any help would be appreciated.  Thanks, Anish

Yes it is easy, just google for PWM verilog, or PWM VHDL.

interesting. I thought only PIC can do this.
