poke io as different format using bundle in PeekPokeTester

[hukangha]

Hi,
I'm using peekpoketester for this case which I need to reinterpret some data io as command

class DMACommandInterface(val numCMDs:Int)
                         (val memAddrWidth:Int)
                         (val nocDataWidth:Int)
                         (val nNodesX:Int,val nNodesY:Int)
  extends Bundle{
  val cmd         = UInt(log2Ceil(numCMDs).W)
  val srcAddr     = UInt(memAddrWidth.W)
  val destAddr    = UInt(memAddrWidth.W)
  val dataSize    = UInt(memAddrWidth.W)
  val nocX        = UInt(log2Ceil(nNodesX).W)
  val nocY        = UInt(log2Ceil(nNodesY).W)
  val dummy       = UInt((nocDataWidth-log2Ceil(numCMDs)-memAddrWidth*3).W)
  override def cloneType :this.type = (new DMACommandInterface(numCMDs)
  (memAddrWidth)(nocDataWidth)(nNodesX,nNodesY)).asInstanceOf[this.type]
}

class DMATxTester(c :DMATx) extends PeekPokeTester(c){

......

  val dmaCommand = new DMACommandInterface(Commands.numCmds)(c.memAddrWidth)(c.nocDataWidth)(c.nNodesX,c.nNodesY)

......

  poke(c.io.rx.data.asTypeOf(dmaCommand).cmd,read)
  poke(c.io.rx.data.asTypeOf(dmaCommand).srcAddr,addr)
  poke(c.io.rx.data.asTypeOf(dmaCommand).destAddr,addr)
  poke(c.io.rx.data.asTypeOf(dmaCommand).dataSize,size)
  poke(c.io.rx.data.asTypeOf(dmaCommand).nocX,xpos)
  poke(c.io.rx.data.asTypeOf(dmaCommand).nocY,ypos

}

and it reports error:
chisel3.internal.ChiselException: Error: Not in a UserModule. Likely cause: Missed Module() wrap, bare chisel API call, or attempting to construct hardware inside a BlackBox.

and if I use SteppedHWIOTester

...
poke(c.io.rx.data.asTypeOf(dmaCommand).cmd,1)
...

it reports
key not found: chisel3.core.UInt@363

So, how do we do this ?

I saw that tester2 is used for this.
