Chisel 学习笔记（二）

Chisel 

新建Chisel项目

方式一

将如下链接中的项目下载至本地。
enter description here
更改工程名称。
删除.git，并将build.sbt中的name改成自己项目的名称。
删除source>main>scala中的文件和source>test>scala中的文件。
得到纯净版。

方式二

新建scala项目，选择sbt
scala版本选择2.11.12,sbt版本随意
将下方sbt替换build.sbt

build.sbt

def scalacOptionsVersion(scalaVersion: String): Seq[String] = {
  Seq() ++ {
    // If we're building with Scala > 2.11, enable the compile option
    //  switch to support our anonymous Bundle definitions:
    //  https://github.com/scala/bug/issues/10047
    CrossVersion.partialVersion(scalaVersion) match {
      case Some((2, scalaMajor: Long)) if scalaMajor < 12 => Seq()
      case _ => Seq("-Xsource:2.11")
    }
  }
}

def javacOptionsVersion(scalaVersion: String): Seq[String] = {
  Seq() ++ {
    // Scala 2.12 requires Java 8. We continue to generate
    //  Java 7 compatible code for Scala 2.11
    //  for compatibility with old clients.
    CrossVersion.partialVersion(scalaVersion) match {
      case Some((2, scalaMajor: Long)) if scalaMajor < 12 =>
        Seq("-source", "1.7", "-target", "1.7")
      case _ =>
        Seq("-source", "1.8", "-target", "1.8")
    }
  }
}

name := "Module-2.1"	//项目名称

version := "0.1"			//自己给项目起的版本号

scalaVersion := "2.11.12"	//scala版本

crossScalaVersions := Seq("2.11.12", "2.12.4")		//scala版本的扩充

resolvers ++= Seq(
  Resolver.sonatypeRepo("snapshots"),
  Resolver.sonatypeRepo("releases")
)

// Provide a managed dependency on X if -DXVersion="" is supplied on the command line.
val defaultVersions = Map(
  "chisel3" -> "3.1.+",
  "chisel-iotesters" -> "1.2.5+"
)

libraryDependencies ++= Seq("chisel3","chisel-iotesters").map {
  dep: String => "edu.berkeley.cs" %% dep % sys.props.getOrElse(dep + "Version", defaultVersions(dep)) }

scalacOptions ++= scalacOptionsVersion(scalaVersion.value)

javacOptions ++= javacOptionsVersion(scalaVersion.value)
