3.1.6.1. Example Design PHY and Packet Generator Loopback Test

You can access Example Design PHY and Packet Generator Loopback Test tab only if you are using a Quartus® Prime generated design example.
When you turn on the Run Test in External Loopback Mode option, the internal serial loopback is disabled for the IP. When you turn on the Start PHY and Packet Generator Loopback Test option, the test procedure runs a series of processes as shown in the figure below.
Note: To successfully run the external loopback mode you must connect an external loopback module to the corresponding Ethernet port in your design.
