Modelsim自动化仿真之do文件书写

1. 创建本地库

   vlib ./work

   You must use vlib rather than operating system commands to creat a library directory or index file.

2. 映射逻辑库到物理目录

   vmap work ./work

3. 编译源代码（缺省编译到 work 本地库）

   vlog ./../design/*.v

   vlog ./tb_div_odd.v

   可以使用 "- work" 指定编译到哪个库中

4. 启动仿真器

   vsim -voptargs=+acc work.tb_div_odd

5. 添加波形

   add wave tb_div_odd/*

6. 执行仿真

   run -all

示例 run.do 文件如下所示：

# 退出当前仿真
quit  -sim

# 清输出窗口
.main clear

# 创建本地库
# You must use vlib rather than operating system commands to creat a library directory or index file.
vlib  ./work
vlib  ./altera_lib

# 将逻辑库名映射库路径
vmap  work        ./work
vmap  alt_lib     ./altera_lib

# 编译 verilog 源代码
# 其中的 "- work" 参数用来具体指定将 verilog 源代码编译到哪个库中，缺省编译到 work 库
vlog  -work  alt_lib     ./altera_mf.v
vlog  -work  alt_lib     ./../quartus_prj/ipcore_dir/pll_1.v
vlog  -work  work        ./../design/*.v
vlog  -work  work        ./tb_ipcore_pll.v

# 启动仿真器
vsim  -voptargs=+acc  -L alt_lib  -L work  work.tb_ipcore_pll

# 添加波形
add   wave   tb_ipcore_pll/*

# 执行仿真
run   1us

参考 run.do 文件如下所示：
