Testbench Output Example: 100GbE IP Core with Adapters
This section shows successful simulation using the 100GbE IP core with adapters testbench (
alt_100gbe_
tb.sv
). The testbench connects the Ethernet TX lanes to the Ethernet RX lanes, so that the IP core is in an
external loopback configuration. In simulation, the testbench resets the IP core and waits for lane
alignment and deskew to complete successfully. The packet generator sends ten packets on the Ethernet
TX lanes and the packet checker checks the packets when the IP core receives them on the Ethernet RX
lanes.
The successful testbench run displays the following output:
