    Declare a port as master or slave

    Declare a port as master or slave

    There are 4 available syntaxes, which are all equivalent:

    val braces = master(Flow(Bool))

val short = master Flow (Bool)

val spaceful = master port Flow(Bool)

val variadic = Flow(Bool)
master(variadic)

    The "braces" syntax is short and generic, but it uses braces.

    The "short" syntax is short, but it is formatted with a space between the type and its parameters, and it can be used only with:

    • Flow
    • Stream

    The "spaceful" syntax is generic and beautiful, but more verbose.

    The "variadic" syntax can be used with any number of interfaces, but can be used only if the interfaces are already declared.

  52. class PackedBundle extends Bundle

    Similar to Bundle but with bit packing capabilities.

    Similar to Bundle but with bit packing capabilities. Use pack implicit functions to assign fields to bit locations - pack(Range, [Endianness]) - Packs the data into Range aligning to bit Endianness if too wide - packFrom(Position) - Packs the data starting (LSB) at Position. Uses full data length - packTo(Position) - Packs the data ending (MSB) at Position. Uses full data length

    Providing no location tag will place the next data value immediately after the last.

    Example: 

    1. val regWord = new PackedBundle {
  val init = Bool().packFrom(0) // Bit 0
  val stop = Bool() // Bit 1
  val result = Bits(16 bit).packTo(31) // Bits 16 to 31
}
  53. class PackedWordBundle extends PackedBundle

    An enhanced form of PackedBundle with Word-centric packing.

    An enhanced form of PackedBundle with Word-centric packing. Offers all the same implicit packing assignment functions, but applies packing to an assigned word. - inWord(WordIndex) - Indicates which word to pack into. Must be used after a pack assigment. If no pack range was given then the entire data length will be assumed. Ranges that exceed the word will wrap into subsequent words.

    Like PackedBundle, providing no pack or word assignments will place data immediately after the last.

    Example: 

    1. val wordPacked = PackedWordBundle(8 bits) {
  val aNumber = UInt(8 bits).word(0) // Bits 7 downto 0
  val bNumber = UInt(8 bits).pack(0 to 7).word(1) // Bits 8 to 15
  val large   = Bits(18 bits).word(2) // Bits 33 downto 16
  val flag    = Bool() // Bit 34

  64. class Stream[T <: Data] extends Bundle with IMasterSlave with DataCarrier[T]

    A simple interface with master payload valid, slave ready handshake.

    A simple interface with master payload valid, slave ready handshake.

    When manually reading/driving the signals of a Stream keep in mind that:

    • After being asserted, valid may only be deasserted once the current payload was acknowledged. This means valid can only toggle to 0 the cycle after a the slave did a read by asserting ready.
    • In contrast to that ready may change at any time.
    • A transfer is only done on cycles where both valid and ready are asserted.
    • valid of a Stream must not depend on ready in a combinatorial way and any path between the two must be registered.

    It is recommended that valid does not depend on ready at all.

  82. class StreamFork[T <: Data] extends Component

    A StreamFork will clone each incoming data to all its output streams.

    A StreamFork will clone each incoming data to all its output streams. If synchronous is true, all output streams will always fire together, which means that the stream will halt until all output streams are ready. If synchronous is false, output streams may be ready one at a time, at the cost of an additional flip flop (1 bit per output). The input stream will block until all output streams have processed each item regardlessly.

    Note that this means that when synchronous is true, the valid signal of the outputs depends on their inputs, which may lead to dead locks when used in combination with systems that have it the other way around. It also violates the handshake of the AXI specification (section A3.3.1).
