What's the best way to test an AXIModule?

[bathtub-01]

Hi. I'm currently using this library to create AXI interfaces in my work. But I have some problems when I want to verify my design.

Since AXIModule is extended from Chisel RawModule, it can not be directly tested by Chisel tester. I have tried to wrap the AXIModule into a Chisel Module, but I don't know how to connect AXIModule's port to the wrapper's io, given that the AXIModule doesn't use Chisel IO.

For example, I have:

class ControllerAXI extends AXIModule {
  // implementation
}

class ControllerWrapper extends Module {
  val io = IO(new ControllerAXIIO)
  val ctl = Module(new ControllerAXI)
  // don't know how to bridge them...
}

So could you please give me a hint on how to test an AXIModule?
