2.8.1. Testbench Behavior

The testbenches send traffic through the IP core in transmit-to-receive loopback mode, exercising the transmit side and receive side of the IP core in the same data flow. These testbenches send traffic to allow the Ethernet lanes to lock, and then send packets to the transmit client data interface and check the data as it returns through the receive client data interface.

Figure 8.  LL 100GbE IP Core Testbench The top-level testbench file consists of a simple packet generator and checker and one IP core in a loopback configuration.
