StreamArbiterFactory

class StreamArbiterFactory extends AnyRef

Build a StreamArbiter from a list of Stream.

example:

val streamA, streamB, streamC = Stream(Bits(8 bits))
val arbiteredABC = StreamArbiterFactory.roundRobin.onArgs(streamA, streamB, streamC)
val streamD, streamE, streamF = Stream(Bits(8 bits))
val arbiteredDEF = StreamArbiterFactory.lowerFirst.noLock.onArgs(streamD, streamE, streamF)
