Axi4Master

case class Axi4Master(axi: Axi4, clockDomain: ClockDomain, name: String = "unnamed") extends Product with Serializable

Simulation master for the Axi4 bus protocol spinal.lib.bus.amba4.axi.Axi4.

axi

bus master to drive

clockDomain

clock domain to sample data on

Example: 

  1. SimConfig.compile(new Component {
  val io = new Bundle {
    val axiSlave = slave(Axi4(Axi4Config(32, 32)))
  }
  io.axiSlave.assignDontCare
}).doSim("sample") { dut =>
  val master = Axi4Master(dut.io.axiSlave, dut.clockDomain)
  val data = master.read(0x1000, 4)
}

  16. def read(address: BigInt, totalBytes: BigInt, id: Int = 0, burst: Axi4Burst = Incr, len: Int = 0, size: Int = maxSize): List[Byte]

    Read synchronously multiple bytes from the specified address.

    Read synchronously multiple bytes from the specified address.

    address

    address to read from; does not need to be aligned (data will be truncated automatically)

    totalBytes

    total number of bytes in the result; if longer than a single transaction (as specified by burst, len, and size), the bus master will issue multiple transactions

    id

    AxID to use in the request; xID in the response will be checked against this (cf. AXI specification)

    burst

    burst mode to issue (cf. AXI specification)

    len

    number of beats in a single transaction minus one (cf. AXI specification)

    size

    number of bytes in one beat, log encoded (cf. AXI specification)

  17. def readCB(address: BigInt, totalBytes: BigInt, id: Int = 0, burst: Axi4Burst = Incr, len: Int = 0, size: Int = maxSize)(callback: (List[Byte]) ⇒ Unit): Unit

    Read asynchronously; same as read, but result is delivered in a callback

    Read asynchronously; same as read, but result is delivered in a callback

    callback

    callback function on finish

  18. def readIdle: Boolean

    check if all read channels are idle (no read transactions active)

  19. def readSingle(address: BigInt, totalBytes: Int, id: Int = 0, burst: Axi4Burst = Incr, len: Int = 0, size: Int = maxSize)(callback: (List[Byte]) ⇒ Unit): Unit

    Read asynchronously with only one transaction

  20. def reset(): Unit

    Reset bus master (dropping all pending transactions)

    Write synchronously multiple bytes to the specified address.

    Write synchronously multiple bytes to the specified address.

    address

    address to write to; does not need to be aligned (data will be truncated automatically)

    data

    list of bytes to write to address; if longer than a single transaction (as specified by burst, len, and size), the bus master will issue multiple transactions

    id

    AxID to use in the request; xID in the response will be checked against this (cf. AXI specification)

    burst

    size

    number of bytes in one beat, log encoded (cf. AXI specification)

  26. def writeCB(address: BigInt, data: List[Byte], id: Int = 0, burst: Axi4Burst = Incr, len: Int = 0, size: Int = maxSize)(callback: ⇒ Unit): Unit

    Write asynchronously; same as write, but completion is delivered in a callback

    Write asynchronously; same as write, but completion is delivered in a callback

    callback

    callback function on finish

  27. def writeIdle: Boolean

    check if all write channels are idle (no write transactions active)

  28. def writeSingle(address: BigInt, data: List[Byte], id: Int = 0, burst: Axi4Burst = Incr, len: Int = 0, size: Int = maxSize)(callback: ⇒ Unit): Unit
