De2-115 windows application to control Cyclone chip

Hi

Again please lets take an example.

in DE2.VHD top, I just need to connect all port.

e.g. I have:

port (

-- Input clocks

clk_50MHz : in std_logic;

clk_27MHz : in std_logic;

clk_sma : in std_logic;

-- SDRAM

sdram_clk : out std_logic;

sdram_cke : out std_logic;

sdram_csN : out std_logic;

sdram_rasN : out std_logic;

sdram_casN : out std_logic;

sdram_weN : out std_logic;

sdram_ba : out std_logic_vector( 1 downto 0);

sdram_addr : out std_logic_vector(11 downto 0);

sdram_dqm : out std_logic_vector( 1 downto 0);

sdram_dq : inout std_logic_vector(15 downto 0);

etc.

So I need to see that in my constrains file I have same names.

And if not -> should fix it in DE2.VHD file

lets take from DE2.VHD more example, I have in file port:

-- LCD

lcd_on : out std_logic;

now in constrains.tcl I have line with:

set_location_assignment PIN_L5 -to LCD_ON

;# LCD Back Light ON/OFF (not working)

so since they both LCD_ON (except capital letters, does it matter?)

=> so this is all good, and this port doesn't need any change at all.

Right?

Thanks,

Roee
