class Counter extends AffectsChiselPrefix

Used to generate an inline (logic directly in the containing Module, no internal Module is created) hardware counter.

Typically instantiated with apply methods in object Counter

Does not create a new Chisel Module

Examples: 

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

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