The TbAXI4.vhd contains AXI4 Manager and Subordinate along with the Test controller/sequencer called TestCtrl. It also contains clock and reset source.
There is one more thing called Axi4Monitor. I found a source file called Axi4Monitor_dummy.vhd which has an entity but empty architecture. Does this mean that the monitor module is not yet completed and shall be complete some time in the future?
Is this supposed to be a monitor module that detects protocol violations?
