在 Chisel 中使用 SteppedHWIOTester 时出错

Question

我根据https://github.com/freechipsproject/chisel-testers/wiki/Using-the-Hardware-IO-Testers用SteppedHWIOTester写了一个加法器，但是有问题：

import chisel3._
import chisel3.iotesters.{SteppedHWIOTester, ChiselFlatSpec}

class Adder (val w:Int) extends Module {
  val io = IO(new Bundle {
    val in0 = Input(UInt(w.W))
    val in1 = Input(UInt(w.W))
    val out = Output(UInt(w.W))
  })
  io.out := io.in0 + io.in1
}


class AdderTests extends SteppedHWIOTester {
  val device_under_test = Module( new Adder(10) )
  val c = device_under_test
  enable_all_debug = true

  rnd.setSeed(0L)
  for(i<-0 until 10) {
    val in0 = rnd.nextInt(1 << c.w)
    val in1 = rnd.nextInt(1 << c.w)
    poke(c.io.in0, in0)
    poke(c.io.in1, in1)
    expect(c.io.out, (in0 + in1) & ((1 << c.w) - 1))

    step(1)
  }
}

class AdderTester extends ChiselFlatSpec {
  "Adder" should "compile and run without incident" in {
     assertTesterPasses { new AdderTests }
  }
}

错误是：

那么我该怎么做才能解决它？非常感谢！

这听起来像是一个不匹配的库问题。您能否尝试清除常春藤缓存中的凿子库并重新运行。要清除 unix-y 类型机器上的缓存，只需运行即可。

rm -rf ~/.ivy2/cache/edu.berkeley.cs/*

如果您在本地构建了任何凿子套件，我建议您从存储库中提取最新版本并重新发布。
