Question

顶部模块如下；

sbt 'test:runMain noc.PEMain'

我认为这是凿子3的普通样式。我执行以下sbt来 lint 代码；

[warn] Multiple main classes detected.  Run 'show discoveredMainClasses' to see the list
[info] Running noc.NoCMain

然后我收到下面的错误消息；

[error] (Test / runMain) Nonzero exit code: 1

最后这个错误：

[warn] Multiple main classes detected.  Run 'show discoveredMainClasses' to see the list

我发现以下警告：

sbt 'show discoveredMainClasses'

显示[info] Loading settings from plugins.sbt ... [info] Loading project definition from /Users/hoge/Desktop/NoC/project [info] Loading settings from build.sbt ... [info] Set current project to en-noc (in build file:/Users/hoge/Desktop/NoC/) [info] * [success] Total time: 1 s, completed 2019/10/22 2:08:49的命令；

sbt 'testOnly noc.PETester'

此错误消息是什么意思，我该如何解决？

[info]   at chisel3.core.LegacyModule.<init>(UserModule.scala:127)

介绍了

    val io = IO(new Bundle {
        val No = Output(Vec(NumLinks, UInt((log2Ceil(NumLinks)).W)))
    })

这是由于

    port := os.Getenv("PORT")
    if port == "" {
            port = "8080"
            log.Printf("Defaulting to port %s", port)
    }
    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", port), nil))

看来主要问题是：

attempted to instantiate a Module without wrapping it in Module()

这可能是因为您创建了一个从 Module 扩展的类的新实例，但您可能没有将它包装成一个。例如你在你的代码中你正在做这样的事情：

val test = new module_class

你应该做什么 val 测试 = 模块（新模块类）

错误：尝试实例化模块而不将其包装在Module（）中
