Hi everyone,while i'm designing my VHDL project,i experience very strange problem which is my development kit's expansion header's pins don't work.I assingment my output variables to kit's led ports there is no problem all leds do what i want but i assingment to kit's J4 expansion header and pff there is nothing.Here is my UCF code and my development kit's datasheet:

Code:
NET "clock" LOC = "C9" | IOSTANDARD = LVCMOS33 ;
NET "clock" PERIOD = 20ns HIGH 40%;
NET "buton(0)" LOC = "L13" | IOSTANDARD = LVTTL | PULLUP ;#sw0 buton
NET "buton(1)" LOC = "L14" | IOSTANDARD = LVTTL | PULLUP ;#sw1 buton
NET "motorizin" LOC = "H18" | IOSTANDARD = LVTTL | PULLUP ;#sw2 buton
#Problem code begin
NET "cikis(0)" LOC = "D7" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 6 ;#J4 header 0.port
NET "cikis(1)" LOC = "C7" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 6 ;#J4 header 1.port
NET "cikis(2)" LOC = "F8" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 6 ;#J4 header 2.port
NET "cikis(3)" LOC = "E8" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 6 ;#J4 header 3.port
#problem code end
NET "led(0)" LOC = "E6" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8 ;
NET "led(1)" LOC = "D6" | IOSTANDARD = LVTTL | SLEW = SLOW | DRIVE = 8 ;
