与信号微调相关的映射误差 [英] Mapping Error related to trimming of signals
问题描述
我解决了之前的错误，但系统不允许我创建一个新问题，这就是我编辑当前问题的原因.现在我在地图中遇到这样的错误:
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:

我还附上了我的 ucf 代码:
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;
此外，当主程序在 Verilog 中时，这个 ucf 可以正常工作.请帮帮我
Also, this ucf worked as desired when main program was in Verilog. Please help me out
推荐答案
至少在第二个过程中，if ... end if 是不平衡的，因此缺少了一些 结束如果的.可能还有其他问题；正如皮贝尔所问；什么是第 119 行?
At least in the second process, the if ... end if ain't balanced, thus there are missing some end if's. There may be other issues also; as Peabbels asks; what is line 119 ?
尝试根据控制结构缩进代码，因为这很容易显示语法问题.使用 Emacs VHDL 美化显示如下代码:
Try to indent the code according to the control structure, since this easily shows syntax problems. Using Emacs VHDL beautify shows the code like:
process(bit_count, ac97_sync, ac97_bit_clock, ac97_sdata_out, command_data, command_address, frame_count)
begin
-- Generate the sync signal
if (bit_count <= "11111111")then
ac97_sync <= '1';
if (bit_count <= "00001111")then
ac97_sync <= '0';
if ((bit_count >= "00000000") and (bit_count <= "00001111"))then
-- Slot 0: Tags
case bit_count is
when "00000000" => ac97_sdata_out <= '1';
when "00000001" => ac97_sdata_out <= '1';
when "00000010" => ac97_sdata_out <= '1';
when others => ac97_sdata_out <= '0';
end case;
else
if ((bit_count >= "00010000") and (bit_count <= "00100011"))then
-- Slot 1: Command address
abc <= std_logic_vector(35 - unsigned(bit_count));

ac97_sdata_out <= command_address(def);
else
