参考 https://blog.youkuaiyun.com/leishangwen/article/details/46225587 建立一个chisel_max目录，文件内容如后面所述，现在开始执行命令：

joe@joe-Aspire-Z3730:/media/sdb4/download/scala$ cd chiseltest
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/chiseltest$ ls
chisel_max
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/chiseltest$ cd chisel_max/
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/chiseltest/chisel_max$ ls

通过上面的命令可以看到执行成功了，但我没有在目录中找到Max2.v文件（verilog文件），然后我再参考 https://github.com/freechipsproject/chisel3 中所说，安装verilator模块:

joe@joe-Aspire-Z3730:/media/sdb4/download/scala$ git clone http://git.veripool.org/git/verilator
Cloning into 'verilator'...

再执行命令

joe@joe-Aspire-Z3730:/media/sdb4/download/scala$ cd verilator
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/verilator$ ls

Already up-to-date.
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/verilator$ git checkout verilator_3_904
Note: checking out 'verilator_3_904'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at 0253017... Version bump

说明现在的分支与当时的情况不一样了，需要我重新再checkout.

joe@joe-Aspire-Z3730:/media/sdb4/download/scala/verilator$ git checkout -b verilator_3_904
Switched to a new branch 'verilator_3_904'
joe@joe-Aspire-Z3730:/media/sdb4/download/scala/verilator$ git checkout

虽然我安装verilator成功了，回到Max2目录中重新执行sbt和run命令之后还是没有看到Max2.v文件。不知为什么会这样？？？？

另外，参考使用SBT构建Scala应用

https://github.com/CSUG/real_world_scala/blob/master/02_sbt.markdown 有sbt的祥细介绍，包括如何配置sbt的build.sbt及scala语法形式的build.sbt（要放在项目根目录下即 project目录下）
