Examples: 

  1. // Using Scala Range API
val (counterValue, counterWrap) = Counter(0 until 10 by 2)
when (counterValue === 4.U) {
  ...
}
    2. , 

  2. val countOn = true.B // increment counter every clock cycle
val (counterValue, counterWrap) = Counter(countOn, 4)
when (counterValue === 3.U) {
  ...
