class RRArbiter[T <: Data] extends LockingRRArbiter[T]

Hardware module that is used to sequence n producers into 1 consumer. Producers are chosen in round robin order.

Example:
  1. val arb = new RRArbiter(2, UInt())
    arb.io.in(0) <> producer0.io.out
    arb.io.in(1) <> producer1.io.out
    consumer.io.in <> arb.io.out

    This must wrap the datatype used to set the io field of any Module.

    This must wrap the datatype used to set the io field of any Module. i.e. All concrete modules must have defined io in this form: [lazy] val io[: io type] = IO(...[: io type])

    Items in [] are optional.

    The granted iodef WILL NOT be cloned (to allow for more seamless use of anonymous Bundles in the IO) and thus CANNOT have been bound to any logic. This will error if any node is bound (e.g. due to logic in a Bundle constructor, which is considered improper).

    Also registers a Data as a port, also performing bindings. Cannot be called once ports are requested (so that all calls to ports will return the same information). Internal API.

    TODO(twigg): Specifically walk the Data definition to call out which nodes are problematic.

    Compatibility function.

    Compatibility function. Allows Chisel2 code which had ports without the IO wrapper to compile under Bindings checks. Does nothing in non-compatibility mode.

    Should NOT be used elsewhere. This API will NOT last.

    TODO: remove this, perhaps by removing Bindings checks in compatibility mode.
