在XILINX ISE的安装目录下\BIN\NT\有COMPLXLIB.EXE，可以编译XILINX的库。但前提是XILINX要新版本，好像是5.1之后吧。具体格式：
compxlib -s mti_se -f all -l vhdl -o e:\Modeltech_5.8a
其中最后的是MODELSIM的安装目录。做完之后需要手动修改MODELSIM.INI文件让MODELSIM启动时可以找到配置，如下：
[Library]
std = $MODEL_TECH/../std
ieee = $MODEL_TECH/../ieee
verilog = $MODEL_TECH/../verilog
std_developerskit = $MODEL_TECH/../std_developerskit
synopsys = $MODEL_TECH/../synopsys
modelsim_lib = $MODEL_TECH/../modelsim_lib
logiblox = $MODEL_TECH/../logiblox
uni9000 = $MODEL_TECH/../uni9000
simprim = $MODEL_TECH/../simprim
simprims_ver = $MODEL_TECH/../simprims_ver
unisim = $MODEL_TECH/../unisim
unisims_ver = $MODEL_TECH/../unisims_ver
xilinxcorelib = $MODEL_TECH/../xilinxcorelib
xilinxcorelib_ver = $MODEL_TECH/../xilinxcorelib_ver
