反转Chisel3中的输入

Question

I want to reverse the input signal in Chisel3. For instance, if the input is 12345678 , I want the output to be 87654321 . Can anyone please help me with this?

Code:

import chisel3._
import chisel3.util._
import chisel3.iotesters.{ChiselFlatSpec, Driver, PeekPokeTester}
import chisel3.util.Reverse

class Length extends Module {

val in     = Input(UInt(64.W))

val out    = Output(UInt(8.W))  

out := Reverse(in.x)

}

Answer 1

The solution which was discussed in comments:

import chisel3._
import chisel3.util.Reverse

class Length extends Module {
  val io = IO(
    new Bundle {
      val in  = Input(UInt(64.W))
      val out = Output(UInt(8.W))
    }
  )
  io.out := Reverse(io.in)
}
