class Arbiter[T <: Data] extends Module
Hardware module that is used to sequence n producers into 1 consumer. Priority is given to lower producer.

- def IO[T <: Data](iodef: => T)(implicit sourceInfo: SourceInfo): T
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 must be a chisel type and not be bound to hardware.
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.

- def _bindIoInPlace(iodef: Data)(implicit sourceInfo: SourceInfo): Unit
Chisel2 code didn't require the IO(...) wrapper and would assign a Chisel type directly to io, then do operations on it.
Chisel2 code didn't require the IO(...) wrapper and would assign a Chisel type directly to io, then do operations on it. This binds a Chisel type in-place (mutably) as an IO.

Takes the first seed suggested.
Takes the first seed suggested. Multiple calls to this function will be ignored. If the final computed name conflicts with another name, it may get uniquified by appending a digit at the end.
Is a higher priority than
autoSeed, in that regardless of whetherautoSeedwas called, suggestName will always take precedence.- seed
