I resolved the previous error but system is not allowing me to create a new question that's why i am editing the current one. Now i am getting an error in map like this:

I am also attaching my ucf code:
NET "clock" LOC="V10" | IOSTANDARD=LVCMOS33 | CLOCK_DEDICATED_ROUTE=FALSE;
#
# Audio CODEC
#
NET "audio_reset_b" LOC="K15" | IOSTANDARD = LVCMOS33 | DRIVE = 8 | SLEW = FAST ;
NET "ac97_sdata_out" LOC="H18" | IOSTANDARD = LVCMOS33 | DRIVE = 8 | SLEW = FAST ;
NET "ac97_sdata_in" LOC="J16" | IOSTANDARD = LVCMOS33 | DRIVE = 8 | SLEW = FAST ;
NET "ac97_sync" LOC="K16" | IOSTANDARD = LVCMOS33 | DRIVE = 8 | SLEW = FAST ;
NET "ac97_bit_clock" LOC="J18" | IOSTANDARD = LVCMOS33 | DRIVE = 8 | SLEW = FAST | CLOCK_DEDICATED_ROUTE=FALSE;
Also, this ucf worked as desired when main program was in Verilog. Please help me out
At least in the second process, the
if ... end ifain't balanced, thus there are missing someend if's. There may be other issues also; as Peabbels asks; what is line 119 ?Try to indent the code according to the control structure, since this easily shows syntax problems. Using Emacs VHDL beautify shows the code like:
