System and method for performing on-chip self-testing

A method for determining whether a physical layer device under test is defective, the method comprising:

• establishing a closed communication path between a verified physical layer device and the physical layer device under test via an electrical interface of said verified physical layer device and an electrical interface of the physical layer device under test;
• configuring the physical layer device under test to operate in loopback mode;
• generating test packets from said verified physical layer device to be communicated over said established closed communication path;
• receiving at least a portion of said test packets at said verified physical layer device from the physical layer device under test communicated via said established closed communication path;
• and
• comparing at least a portion of said received test packets with at least a portion of said generated test packets, to determine whether the physical layer device under test is defective.
