First of all thanks for your time to read this post...
OK I am trying to implement a simple project to test a board with a Xilinx XC2C256 CPLD.
I have managed to create a .ucf file with the Reference Manual page 6.
and then i created a toplevel file to interact with the IO:
As you can see all i have done was to crete a module with all the IO pins Clock and a Button wich i connected like this:
Whem i implement the design i get this error:
Can some one tell me what the problem is? Does it mean i cannot connect a IO to another directly?
Thanks for all the help....

assign D40=1'b0;
assign D38=1'b1;
assign D37 = D36;Whem i implement the design i get this error:
Code:
ERROR:Cpld:832 - 'D37' is assigned to an invalid location ('48') for this
device. This will prevent the design from fitting on the current device.
'D37' must be reassigned before attempting a re-fit.
ERROR:Cpld:868 - Cannot fit the design into any of the specified devices with
the selected implementation options.Can some one tell me what the problem is? Does it mean i cannot connect a IO to another directly?
Thanks for all the help....
