Axi4StreamMaster

case class Axi4StreamMaster(axis: Axi4Stream, clockDomain: ClockDomain, nullSegmentProb: Double = 0.0, maxNullSegment: Int = 0) extends Product with Serializable

Simulation master for the Axi4Stream bus protocol Axi4Stream.

axis

bus master to drive

clockDomain

clock domain to sample data on

nullSegmentProb

probability to insert null segment at any byte offset (between 0 and 1); default to 0.0 (no null bytes inserted)

maxNullSegment

maximum length of null (TKEEP=0) segment in the middle of the stream; default to 0 (no null bytes)

Example: 

  1. SimConfig.compile(new Component {
  val io = new Bundle {
    val axisSlave = slave(Axi4Stream(Axi4StreamConfig(32)))
  }
  io.axisSlave.assignDontCare
}).doSim("sample") { dut =>
  val master = Axi4StreamMaster(dut.io.axisSlave, dut.clockDomain)
  master.send(Random.nextBytes(256).toList)
}
