Thanks in advance!

xps ucf

thx! i've read up on that

but the prob now is.. if i can use ISE's .ucf file in XPS.. izzit the same?

i've actaully tried to add in some codes for pinout in XPS's .ucf file

# VGA port
NET "vga_r" LOC = "R12" ;
NET "vga_g" LOC = "T12" ;
NET "vga_b" LOC = "R11" ;
NET "vga_hs" LOC = "R9" ;
NET "vga_vs" LOC = "T10" ;

# PS2 port
NET "ps2_d" LOC = "M15" ;
NET "ps2_c" LOC = "M16" ;

i found these codes on net.. when i generate the bitstream this is the error msg i've got.

Applying constraints in "system.ucf" to the design...

any idea how to solve this?

xps error in ucf

1) Make empty ucf file.
2) Run constrain editor in ISE
3) Find correct signal name and use it in UCF file

setting ucf xilinx

oh thx alot! but ermm.. could u elaborate more on the methods? hm kindda confuse coz im not familiar wif the equipments..

.UCF in XPS and ISE both are more or less same

In your case
once BSB is done .UCF file will be created in XPS project just open it(contails all top level ports) and edit .
If you are not comforatable with this you can use ISE's UCF
But make sure that all toplevel ports of your XPS project matches with the port names in UCF..
If not look in to external ports in XPS and change accordin to it
