Hello World VHDL (Blinking LED): 

entity LEDtest is
  port (
    clk: in bit;
	 LED1: out bit;
	 LED2: out bit
  );
end LEDtest;

architecture BEHAVIOUR of LEDtest is
    signal count: integer range 0 to 16777215;
	 signal tmp:bit:='0';
	 --signal LED1: bit:='0';
	 --signal LED2: bit:='1';
begin
  IN_process: process (clk)
    begin
      if clk'event and clk = '1' then
		  count<=count+1;
		  if count=16777215 then
		    count<=0;
			 tmp<=not tmp;
		    LED1<=tmp;
			 LED2<=not tmp;
		  end if;  
		end if;
    end process;
end BEHAVIOUR;

With the following constraints file: 

# Crystal Clock - use 32MHz onboard oscillator
NET "clk" LOC = "P89" | IOSTANDARD = LVCMOS25 | PERIOD = 31.25ns ;

# Wing1 Column A
NET "LED1" LOC = "P91";	
NET "LED2" LOC = "P92";
