Error with Queue: Chisel.Queue was not properly wrapped into a module() call.

[Kentaro Sano]

Hi,

I could not solve the problem of error with Queue. Could you help me?

I tried to use "Queue" in the following source code. However I got an error message:

[error] ChiselUtil.scala:359: Chisel.Queue was not properly wrapped into a module() call. in class Chisel.Queue

[error] (run-main-0) java.lang.IllegalStateException: 4mCODE HAS 4m1m10m4m 4m31mERRORS0m4m and 4m1m00m4m 4m33mWARNINGS0m

java.lang.IllegalStateException: CODE HAS 1 ERRORS and 0 WARNINGS

        at Chisel.ChiselError$.checkpoint(ChiselError.scala:128)

        at Chisel.Backend.elaborate(Backend.scala:791)

        at Chisel.VerilogBackend.elaborate(Verilog.scala:1086)

        ...

I couldn't find any solution so far. I am happy if I could get any hint.

Many thanks,

================================================================

package Qsys

package mRemoteMM

import Chisel._

import scala.collection.mutable.HashMap

class mRemoteMM_IO(...) extends Bundle {

...

}

class mRemoteMM  extends Module {

  val pW_AVMM_DATA    = ...

  ...

  val io = new mRemoteMM_IO(pW_AVMM_DATA, pW_GLBL_ADDR, pW_LOCL_ADDR,

                            pW_CSRG_ADDR, pW_CSRG_DATA, pW_AVST_DATA)

  //------------------------------------------------------------------------

  // Queue test 

  // WHEN THIS PART IS REMOVED, COMPILATION IS PASSED W/O ERRORS.

  val uFifo = new Queue(UInt(), 256) // entries = 256  (THIS MAKES THE ERROR)

  uFifo.io.enq.ready := io.st_in.ready

  uFifo.io.enq.valid := io.st_in.valid

  uFifo.io.enq.bits  := io.st_in.data

  uFifo.io.deq.ready := io.st_out.ready

  uFifo.io.deq.valid := io.st_out.valid

  uFifo.io.deq.bits  := io.st_out.data

}

object mRemoteMM {

  def main(args: Array[String]): Unit = {

    val cutArgs = args.slice(1, args.length)

    chiselMainTest(cutArgs, () => Module(new mRemoteMM())) {

      c => new mRemoteMM_Tests(c) }

  }

}

you've got to wrap your called to new Queue with Module:

  val uFifo = Module(new Queue(UInt(), 256))
