2.2. Design Example Behavior

The testbench sends traffic through the IP core, exercising the transmit side and receive side of the IP core. In the hardware design example, you can program the IP core in internal serial loopback mode and generate traffic on the transmit side that loops back through the receive side.

To speed up simulation, the IP core simulation model sends alignment marker tags at shorter intervals than required by the IEEE Ethernet standard. The standard specifies an alignment marker interval of 16384 words in each virtual lane. The simulation model with the testbench implements an alignment marker interval of 512 words.
