如何将一些 Bundle 作为 Module 参数传递?

How to pass some Bundles as Module parameters?

我正在编写 wishbone plumbing package 来为我的设计生成互连模块。 在这个名为 wbplumbing 的包中,我为 Wishbone Master 和 Slave 接口声明了两个 Bundle:

class WbMaster (val dwidth: Int,
                val awidth: Int) extends Bundle {
    val adr_o = Output(UInt(awidth.W))
// ...
    val cyc_o = Output(Bool())
    override def cloneType = (new WbMaster(dwidth, awidth)).asInstanceOf[this.type]
}

// Wishbone slave interface
class WbSlave (val dwidth: Int,
               val awidth: Int) extends Bundle {
  val adr_i = Input(UInt(awidth.W))
// ...
  val cyc_i = Input(Bool())
  override def cloneType = (new WbSlave(dwidth, awidth)).asInstanceOf[this.type]
}

我的 Intercon 模块将这两个 Bundle 作为参数:

// Wishbone Intercon Pass Trought : one master, one slave
class WbInterconPT (val awbm: WbMaster,
                    val awbs: WbSlave) extends Module {
  val io = IO(new Bundle{
    val wbm = Flipped(new WbMaster(awbm.dwidth, awbm.awidth))
    val wbs = Flipped(new WbSlave(awbs.dwidth, awbs.awidth))
})
//...
}

我想插入这个 Intercon 的两个模块位于两个名为 spi2wb and mdio 的不同包中。两者都包含带有捆绑包的 wbplumbing 包:

import wbplumbing.WbMaster
import wbplumbing.WbSlave

然后在我的 "top" 模块上导入了这个:

// spi, mdio bus modules
import wbplumbing.WbInterconPT
import wbplumbing.{WbMaster, WbSlave} // <- not sure that usefull
import spi2wb.{Spi2Wb, SpiSlave}
import mdio.{MdioWb, MdioIf}

并像那样实例化它:

  // Wishbone parameters
  val dwidth = 16
  val awidth = 2

  // module instantiation
  val spi2Wb = Module(new Spi2Wb(dwidth, awidth))
  val wbMdio = Module(new MdioWb(mainFreq, targetFreq))
  val wbIntercon = Module(new WbInterconPT(spi2Wb.io.wbm, wbMdio.io.wbs))

然后我得到一个类型错误:

[info] Set current project to spi2ksz (in build file:/pchpch/spi2ksz/)
[info] Compiling 1 Scala source to /pchpch/spi2ksz/target/scala-2.11/classes ...

[error]  required: wbplumbing.WbMaster
[error]   val wbIntercon = new WbInterconPT(spi2Wb.io.wbm, wbMdio.io.wbs)

[error]  found   : mdio.WbSlave

[error]   val wbIntercon = new WbInterconPT(spi2Wb.io.wbm, wbMdio.io.wbs)
[error]                                                              ^
[error] two errors found
[error] (Compile / compileIncremental) Compilation failed

我确定解决方案非常简单,但可以找到解决方法!

好的,这是一个 publishLocal 错误。 在我的设计开始时,我在此处各自的包中声明了 WbSlave 和 WbMaster Bundle。然后我发表了。

然后我写了WbPlumbing 包把它们放在一起。而且我忘记 "re"publishlocal 这两个模块。

有时候,问问题解决问题;)
