Altera 40-Gbps Ethernet MAC and PHY MegaCore Function - Manual (Page 38)

Figure 2-4: 40GBASE-KR4 40GbE IP Core Testbench with Adapters
Illustrates the top-level modules of the 40GBASE-KR4 example testbench that uses adapters. To support
the simulation of auto-negotiation, the testbench uses two instances of the IP core instead of configuring
the IP core in loopback mode.
