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?
