object group

Marks that a module to be ignored in Dedup Transform in Firrtl pass

Source
group.scala
Example: 

  1. class MyModule extends Module {
  val io = IO(new Bundle{
    val a = Input(Bool())
    val b = Output(Bool())
  })
  val reg1 = RegInit(0.U)
  reg1 := io.a
  val reg2 = RegNext(reg1)
  io.b := reg2
  group(Seq(reg1, reg2), "DosRegisters", "doubleReg")
}
Note

Intermediate wires will get pulled into the new instance, but intermediate registers will not because they are also connected to their module's clock port. This means that if you want a register to be included in a group, it must be explicitly referred to in the input list.
