Type Members

1.  case class Wishbone(config: WishboneConfig) extends Bundle with IMasterSlave with Product with Serializable

   This class rappresent a Wishbone bus

   This class rappresent a Wishbone bus

   config

   an istance of WishboneConfig, it will be used to configurate the Wishbone Bus

2.  class WishboneAdapter extends Component

   Create a configurable adaptor for the wishbone bus.

   Create a configurable adaptor for the wishbone bus. It can adapt from a wishbone pipelined interface to a standard one or vice versa

   Example:

   1. val wishboneMaster = Wishbone(wishboneConfig(8,8).pipelined)
      val wishboneSlave = Wishbone(wishboneConfig(16,8))
      val adapter = new WishboneAdapter(wishboneMaster.config, wishboneSlave.config, allowAddressResize = true)
      wishboneMaster <> adapter.io.wbm
      adapter.io.wbs <> wishboneSlave

3.  class WishboneArbiter extends Component

   Create a wishbone Arbiter/multiplexer the arbiter will not switch to other interfaces until the selected master/input CYC line goes to zero

4.  case class WishboneConfig(addressWidth: Int, dataWidth: Int, selWidth: Int = 0, useSTALL: Boolean = false, useLOCK: Boolean = false, useERR: Boolean = false, useRTY: Boolean = false, useCTI: Boolean = false, tgaWidth: Int = 0, tgcWidth: Int = 0, tgdWidth: Int = 0, useBTE: Boolean = false) extends Product with Serializable

   This class is used for configuring the Wishbone class

   This class is used for configuring the Wishbone class

   addressWidth

   size in bits of the address line

   dataWidth

   size in bits of the data line

   selWidth

   size in bits of the selection line, deafult to 0 (disabled)

   useSTALL

   activate the stall line, default to false (disabled)

   useLOCK

   tgaWidth

   size in bits of the tag address linie, deafult to 0 (disabled)

   tgcWidth

   size in bits of the tag cycle line, deafult to 0 (disabled)

   tgdWidth

   size in bits of the tag data line, deafult to 0 (disabled)

   useBTE

   activate the Burst Type Extension, default to false (disabled)

   Example:

   1. val wishboneBusConf = new WishboneConfig(32,8).withCycleTag(8).withDataTag(8)
      val wishboneBus = new Wishbone(wishboneBusConf)

5.  class WishboneDecoder extends Component

   Create a wishbone decoder/demultiplexer

6.  case class WishboneInterconFactory() extends Product with Serializable
7.  class WishboneSlaveFactory extends BusSlaveFactoryDelayed

   This is the slave facotory fot the wishbone bus

8.  case class WishboneToBmb(c: WishboneConfig) extends Component with Product with Serializable
9.  case class WishboneToBmbGenerator()(implicit interconnect: BmbInterconnectGenerator = null) extends Area with Product with Serializable
