我寫了一個帶有 Dma 模塊的示例案例，它是esp-chisel-accelerators 中的一個子模塊，但是當我運行sbt test或運行單個測驗時，出現錯誤：method <init>()V not found
代碼是：
class QuickDMA_test extends FlatSpec with ChiselScalatestTester with Matchers{
behavior of "QuickDMAModule"
// test class body here
it should "read some number to tlb" in {
//test case body here
implicit val parames: Config = (new QuickDMAConfig).toInstance
test(new Wrapper()(parames)).withAnnotations(Seq(WriteVcdAnnotation )) { c =>
c.io.control.wen.poke(false.B)
......
并且 Dma 模塊是
object DmaSize {
private val enums = Enum(8)
val Seq(bytes, wordHalf, word, wordDouble, wordQuad, word8, word16, word32) = enums
def gen: UInt = chiselTypeOf(enums.head)
}
class DmaControl extends Bundle {
val index = UInt(32.W)
val length = UInt(32.W)
val size = DmaSize.gen
}
class DmaIO(val dmaWidth: Int) extends Bundle {
val Seq(readControl, writeControl) = Seq.fill(2)(Decoupled(new DmaControl))
val readChannel = Flipped(Decoupled(UInt(dmaWidth.W)))
val writeChannel = Decoupled(UInt(dmaWidth.W))
}
class DmaRequest(val memorySize: Int) extends Bundle {
val index = UInt(log2Up(memorySize).W)
val length = UInt(log2Up(memorySize).W)
val tpe = Bool()
}
object DmaRequest {
val read: Bool = false.B
val write: Bool = true.B
def init_(memorySize: Int) = {
val a = Wire(new Valid(new DmaRequest(memorySize)))
a.valid := false.B
a.bits.index := DontCare
a.bits.length := DontCare
a.bits.tpe := DontCare
a
}
}
class Dma[A <: Data](size: Int, gen: A, initFile: Option[String] = None) extends Module {
private val dmaWidth = gen.getWidth
val io = IO(Flipped(new DmaIO(dmaWidth)))
val req = RegInit(DmaRequest.init_(size))
/* Only one outstanding read or write request at a time */
Seq(io.readControl, io.writeControl).map(_.ready := !req.valid)
val arb = Module(new RRArbiter(new DmaControl, 2))
arb.io.in
.zip(Seq(io.readControl, io.writeControl))
.map{ case (a, b) => a <> b }
我實體一個 Dma 模塊
val dma = Module(new Dma(1024, UInt(bitwidth.W), Some("src/test/resource/linear-mem.txt")))
錯誤是

uj5u.com熱心網友回復：
Scala 生態系統，有點值得期待：您有相互沖突的依賴關系。您的chiseltest.backends.treadle.TreadleExecutive$類檔案包含對該型別的 no-args 建構式的呼叫treadle.stage.TreadleTesterPhase（這<init>()V意味著：這是“具有零引數的建構式”的 JVM-ese。這<init>是“方法”的名稱（建構式在JVM 級別），()包含引數（中間沒有任何引數 - 無引數）并V指示函式回傳void，根據定義所有構造函式都會這樣做。但是，該型別treadle.stage.TreadleTesterPhase存在但內部沒有無引數建構式。
對此的通常解釋是它曾經在某些以前的版本中使用，但現在不再使用，并且您使用的 chiseltest.backends 庫是針對仍然具有它的舊版本編譯的。
修復方法是將您的依賴項更新到最新版本。如果這仍然不起作用，那么 scala 生態系統往往會破壞很多東西并傾向于放棄專案，然后找出兩者中的哪一個“較舊”。如果該專案已被放棄，或者他們是否只是發布更新緩慢，請與網站等聯系。
如果放棄，開始尋找替代品。Scala 不是一個很好的生態系統，可以嘗試將廢棄的專案作為代碼庫的一部分。如果沒有放棄，請降級另一個，直到錯誤消失。

這是一個鏈接錯誤，您的版本不同步。請參閱 Chisel 網站以獲取有關各種專案的哪些版本協同作業的檔案：https : //www.chisel-lang.org/chisel3/docs/appendix/versioning.html
特別是，該存盤庫似乎正在使用與 Chisel 3.2 兼容的專案。您是否完全更改了構建，或者這只是本地構建？
