怎样添加ALTERA的元件库。今天总算可以了。
set LIBPATH D:/altera/90/quartus/eda/sim_lib
vlib sim_lib
vmap sim_lib sim_lib
#vlog -work sim_lib $LIBPATH/altera_mf.v
#vlog -work sim_lib $LIBPATH/altera_primitives.v
#vlog -work sim_lib $LIBPATH/sgate.v
#vlog -work sim_lib $LIBPATH/arriaii_atoms.v
#vlog -work sim_lib $LIBPATH/arriaii_hssi_atoms.v
#vlog -work sim_lib $LIBPATH/220model.v

# 建立一个工作库，
vlib work
vmap work work
# vlog是对verilog文件的编译
vlog E:/modelsim/test3/src/SRAM_TOP.v
vlog E:/modelsim/test3/Testbench/SRAM_TOP_tb.v
此步骤对应于Compile -> Compile All
#vsim命令是开始仿真， -novopt表示不优化
vsim -novopt work.SRAM_TOP_tb
#此步骤对于于Start Simulation中在work库中选择脚本文件和把勾选的Enable Optimization去掉
#添加信号波形，也可以分别添加每一个信号，信号添加的次序是就wave窗口显示的次序，同时可以直接设置信号的类型是10进制，还
是无符号等。
add wave -dec /I_SRAM_TOP/*
add wave -noupdate -radix decimal /gens_tb/i_gens/fsin_o
#看到在这里我们添加的是testbench文件gens_tb中例化的i_gens文件中的fsin_o信号，并把它设置为10进制。
add wave -noupdate -radix decimal /gens_tb/i_gens/fcos_o
在wave波形窗口中点击保存会生成wave.do文件，里面会有在wave窗口中的设置命令。
run 200000 ns
在这里还有一个问题需要验证：在仿真IP时一般要添加库，如果库仿真好了，在编译时可以直接添加，那用tcl应怎样表示呢？

关于几个交互的使用
if [ file exists work ] {
vdel -all
}
/*********************************************************************************/
1、设置路径
cd命令用于更改modelsim的路径，如果仿真正在执行cd命令无效；如果找开了一个工程，那cd命令会关闭当前的工程
语法：cd <dir>
eg:cd e:/fpga
/*********************************************************************************/
2、alias 显示和建立用户定义的别名，有点相当于c语言中的“宏定义”
Syntax
alias [<name> ["<cmds>"]]
当cmds为多组命令时用”；“分开，并且用双引号
eg: alias ld "dev_com;com;elab"
eg2:
alias dev_com {
if [ string match "*ModelSim*" [ vsim -version ] ] {
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_primitives.v" -work altera_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/220model.v" -work lpm_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/sgate.v" -work sgate_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_mf.v" -work altera_mf_ver
vlog -sv "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/altera_lnsim_for_vhdl.sv" -work altera_lnsim_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_atoms_ncrypt.v" -work cyclonev_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_hmi_atoms_ncrypt.v" -work cyclonev_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_atoms_for_vhdl.v" -work cyclonev_ver
vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_hssi_atoms_ncrypt.v" -work cyclonev_hssi_ver

vlog "$QUARTUS_INSTALL_DIR/eda/sim_lib/mentor/cyclonev_pcie_hip_atoms_for_vhdl.v" -work cyclonev_pcie_hip_ver
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_syn_attributes.vhd" -work altera
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_standard_functions.vhd" -work altera

vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_primitives_components.vhd" -work altera

vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/220model.vhd" -work lpm
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/sgate_pack.vhd" -work sgate
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/sgate.vhd" -work sgate
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_mf_components.vhd" -work altera_mf
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_mf.vhd" -work altera_mf
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_lnsim_components.vhd" -work altera_lnsim
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/cyclonev_atoms.vhd" -work cyclonev
vcom "$QUARTUS_INSTALL_DIR/eda/sim_lib/cyclonev_components.vhd" -work cyclonev
}
}
这样的话，在modelsim的命令窗输入dev_com，就会执行所有的编译文件命令。
/*********************************************************************************/
echo 在脚本框中输出指定的内容
Syntax
echo [<text_string>]
如上图，在modelsim的命令行中输入ech "\exec\] com" 就会输出 #[exec] com,其实就相关于matlab 中的output命令
/*********************************************************************************/
eidt
上面的命令用于设置modelsim的文件编辑器
Syntax
edit [<filename>]
[<filename>]用于指定要编辑文件的名字
/********************************************************************************/
proc ensure_lib { lib } { if ![file isdirectory $lib] { vlib $lib } }
个人理解：如果路径中不存在库，就指定ensure_lib用于建立库
vlib可以用于建立一个文件夹
