Instance Constructors

  1. new PRNG(width: Int, seed: Option[BigInt], step: Int = 1, updateSeed: Boolean = false)

    Permalink

    width

    the width of the PRNG

    seed

    the initial state of the PRNG

    step

    the number of state updates per cycle

    updateSeed

    if true, when loading the seed the state will be updated as if the seed were the current state, if false, the state will be set to the seed
