Writing custom testsΒΆ

If you would like to reuse provided tests to test your custom model you will need to write a test file similar to DMAFullMem.

What you need to alter is:

  • Cast buses in the io field accordingly to chosen configuration. Example for AXIS_AXIL_AXI bus configuration:

val io = dut.io.asInstanceOf[Bundle{
			val control: AXI4Lite
			val read: AXIStream
			val write: AXI4
			val irq: InterruptBundle
			val sync: SyncBundle}]

  • You will also need to remember to provide correct BFMs for the test:

val control = new AxiLiteMasterBfm(io.control, peek, poke, println)
val reader = new AxiStreamMasterBfm(io.read, width, peek, poke, println)
val writer = new Axi4SlaveBfm(io.write, width * height, peek, poke, println)

val myConfiguration = new DMAConfig(...)
it should "perform image transfer with my custom configuration" in {
	test(new DMATop(myConfiguration)).runPeekPoke(dut =>
		new ImageTransfer(dut, new <CustomTestClassName>(dut), myConfiguration)
	)
}

After successful test, the image out$(configuration).rgba will be produced (where configuration is the DMA bus configuration).
