ncverilog复杂脚本

ncverilog是Cadence公司的一款Verilog仿真工具，它支持使用TCL脚本批量运行仿真、自动化测试等操作。

下面是一个比较复杂的ncverilog脚本示例：

#!/usr/bin/env tclsh

# define the simulation top level module
set sim_top_module "top_module"

# define the testbench module
set tb_module "testbench"

# define the list of design files
set design_files [list \
  "file1.v" \
  "file2.v" \
  "file3.v" \
]

# define the list of testbench files
set tb_files [list \
  "tb_file1.v" \
  "tb_file2.v" \
]

# define the list of include directories
set include_dirs [list \
  "+incdir1" \
  "+incdir2" \
]

# define the list of define parameters
set define_params [list \
  "+define1" \
  "+define2" \
]

# define the list of additional parameters
set additional_params [list \
  "+access+r" \
  "+notimingchecks" \
]

# define the list of test vectors
set test_vectors [list \
  "test1" \
  "test2" \
  "test3" \
]

# create the simulation object
set sim [new Simulation]

# set the simulation parameters
$sim set_parameter "ncvlog_args" "[join $define_params " "] [join $include_dirs " "]"
$sim set_parameter "ncelab_args" "[join $additional_params " "]"
$sim set_parameter "ncsim_args" "[join $additional_params " "]"

# compile the design files
foreach file $design_files {
  $sim compile $file
}

# compile the testbench files
foreach file $tb_files {
  $sim compile $file
}

# elaborate the design
$sim elaborate $sim_top_module

# run the simulation for each test vector
foreach test $test_vectors {
  # set the test vector parameter
  $sim set_parameter "test" $test

  # run the simulation
  $sim simulate $tb_module
}

# generate the waveform
$sim wave

该脚本包含了以下操作：

1. 定义仿真的顶层模块和测试台模块。
2. 定义设计文件、测试台文件、include目录、define参数等列表。
3. 设置仿真参数，包括ncvlog、ncelab和ncsim的参数。
4. 编译设计文件和测试台文件。
5. 实例化顶层模块。
6. 针对每个测试向量运行仿真，并生成波形。

需要注意的是，该脚本仅供参考，具体的使用方法需要根据实际情况进行修改。
