When instantiating an AXI pass-through VIP, a pass-through agent has to be declared and
constructed. Class axi_passthrough_agent contains other components that
consist of the entire pass-through Verification IP. The pass-through VIP can be switched
to runtime master or runtime slave modes. It includes master read driver, master write
driver, slave read driver, slave write driver, and monitor.
