Hi..

so with the help of eteam00 I was able get my first code working.. however I had a much simplified version and here it is:

module led_simple(
    input clock,
    input reset,
    output led
    );

reg [26:0] count;

always@ (posedge clock or posedge reset)
	begin
		if (reset)
			count <= 0;
		else 
			count <= count + 1;
		end
		
assign led = count[26];

endmodule

 I now want to add this code to my Spartan3E device aso that I can see it in action.

I just dont know hpw to get the programming file.

first I added a ucf file and with the help of the manuals made this .ucf file and added it to the project:

# Pin assignment for LEDs

NET "led" LOC = "m5" ; 

# Pin assignment for pushbutton switches
NET "reset" LOC = "a7"; 

# Pin assignment for clock
NET "clock" LOC = "b8"; 

 here is what I did..

I clicked implementation..

>> Clicked implement design..

>> but got an error in map

ERROR:MapLib:30 - LOC constraint B8 on clock is invalid: No such site on the
   device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'.
ERROR:MapLib:30 - LOC constraint M5 on led is invalid: No such site on the
   device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'.
ERROR:MapLib:30 - LOC constraint A7 on reset is invalid: No such site on the
   device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'.

I cant make sennse of this error and im stuck now.. :(

help please

What device and package do you have selected for your design?  For the Basys2 board, it should be

• Spartan3E family
• XC3S250E device
• CP132 package

Thank you that got the map problems fixed..

ill try to program my device now for the first time =D

ill post here any updates

[farazk86]

alright.. so after I loaded up the program and before programming I got this error..

its attached..

is it serious? should I continue with it anyway?

Thanks

[eteam00]

so after I loaded up the program

What do you mean by 'loaded up the program' ?

and before programming I got this error

Please try to be very specific.  Details are important.

• What software program (or software tool) are you running?  Include version, and operating system you are using.
• What are you trying to do? (example: program FPGA, program flash memory, verify JTAG product ID, etc.)
• What were the steps which led to the error? (if iMPACT, there should be a console log)

sorry, by loaded up I meant using the browse button and selecting the bit file..

and as soon as I pressed the program button i got the above error..

 - I using digilent Adept, windows XP

 - am trying to program the fpga with my counter program.

 - screenshot attached of the software used

[farazk86]

also.. I changed the device to XC3S100E accordingly

[eteam00]

I am completely unfamiliar with the use of the Digilent Adept tool.  There are many folks who use this tool who are better prepared to help you than I, at this point.

Good luck to you....

I found the solution..

When building the project make sure that the startup clock is set appropriately. You can do this in Project Navigator by right clicking on the "Generate Program File" process. Select Properties and then click Startup Options. Set the startup clock to JTAG-CLK or CCLK as appropriate.

and finally I was able to program my device and have my blinking LED..

lol.. i dont know why Im so excited at making an LED blink -.-
