chisel环境搭建(win10 + vscode)

官方下载地址：https://www.oracle.com/cn/java/technologies/javase/downloads/#java8

官方下载地址：https://www.scala-sbt.org/download.html

下载后解压缩，将sbt文件夹放到想要安装的位置
或者直接下载.msi文件后安装

然后配置环境变量：将sbt文件夹下的bin添加到环境变量中的Path中

然后打开sbt文件夹

在/sbt/conf文件夹下创建repo.properties文件，里面加入如下内容：(设置从镜像下载依赖，这里选择的是阿里云的镜像)

[repositories]
local
aliyun: https://maven.aliyun.com/nexus/content/groups/public

在sbtconfig.txt中增加如下内容：

-Dsbt.override.build.repos=true
-Dsbt.repository.config=D:\sbt\conf\repo.properties
-Dsbt.ivy.home=D:\sbt\.ivy\
-Dsbt.log.format=true
-Dsbt.boot.directory=D:\sbt\boot\
-Dsbt.global.base=D:\sbt\.sbt\

注：等号和地址之间不能加空格

在vscode中下载Scala Syntax(official)插件，实现语法高亮

接下来我们写一个程序试验一下：

建立一个文件夹在vscode中打开
在终端中打开cmd，输入sbt，显示没有找到build.sbt，输入c以继续，则会自动生成一些目录

第一次运行sbt时会比较慢

新建文件hello.scala，在里面输入如下内容：

object HelloWorld {
   def main(args: Array[String]) = println("Hello, world!")
}

在cmd中输入compile进行编译，成功
再输入run运行，成功输出"Hello World"

在https://github.com/schoeberl/chisel-empty 上克隆一个叫chisel-empty的文件夹
在建一个chisel项目时，把该文件夹下的build.sbt和scr拷贝到你的项目的文件夹下

在\scr\main\scala下存放自定义的工程文件，在\scr\test\scala 下放测试代码。chisel-empty中自带有一个加法器

文件夹下打开cmd，输入sbt run出现如下信息，chisel可以正常运行，在generated文件夹下可以看到生成的verilog文件

E:\codes\chiseltest>sbt run

输入sbt test，运行测试程序，结果如下

E:\codes\chiseltest>sbt test
