将Chisel测试移植到sbt时出错

Question

我有一个可以工作的窥探式测试仪，在jupyter笔记本上测试过。我正在将它移植到sbt，我已经尝试了两本书和一本我的教授的语法，但到目前为止都没有成功。

项目目录结构基于模板- https://github.com/freechipsproject/chisel-template

我需要移植到sbt的工作基础测试器是-

def test_sync_fifo: Boolean = {
    test(new sync_fifo(64, 32)) { c =>
         // .... Pokes and peeks
    }
    println(getVerilog(new sync_fifo(64, 32)))
    true
}

assert(test_sync_fifo)

我已经试过的是-

import chisel3 ._
import chisel3 . iotesters ._ // Gives error - iotesters not found

class TesterSimple (dut: sync_fifo(64, 32) ) extends
    PeekPokeTester (dut) {        // Gives error = PeekPokeTester not found
    // .. Peeks and pokes
}

object TesterSimple extends App {
    chisel3 . iotesters . Driver (() => new sync_fifo(64, 32)) { c =>
    new TesterSimple (c) 
    }
}

我也试过了-

//In build.sbt - I expect this to be wrong
lazy val scalatest = "org.scalatest" %% "scalatest" % "3.0.5"
libraryDependencies ++= scalatest


import org. scalatest ._
class SimpleSpec extends FlatSpec with Matchers {
" Test " should "pass" in {
    chisel3 . iotesters . Driver (() => new sync_fifo(64, 32)) { c =>
        new Tester (c)
        } should be (true)
    }
}

我也试过了-

import Chisel._

class test_sync_fifo (c: sync_fifo(64, 32))
extends Tester(c) {
    // Peeks and pokes
}

任何指针都会非常有帮助。谢谢

查看完整的SBT文件会很有帮助，但我敢肯定您缺少对iotesters的依赖。假设您使用的是chisel3版本3.4.x或更高版本，您应该在build.sbt中添加以下内容

libraryDependencies += "edu.berkeley.cs" %% "chisel-iotesters" % "1.5.3"

有关不同项目的哪些版本协同工作的信息，请参阅此文档页面：https://www.chisel-lang.org/chisel3/docs/appendix/versioning.html
