Abstract
An interface for implementing a loopback configuration which offers improved calibration and/or testing of an electronic system is disclosed. More specifically, embodiments provide a bi-directional interface with at least two portions or partitions capable of communicating data in opposite directions and implementing a loopback configuration between components of an electronic system, thereby enabling more flexible, efficient and effective calibration and/or testing of the electronic system using a single interface. The loopback of the partitioned bi-directional interface may be used to perform data link training and/or electronic system testing. In one embodiment, the loopback configuration of the interface may be reversible. Additionally, the looped or coupled end of the partitions may be switched from one component to another, thereby reversing the configuration of the loopback in one embodiment. As such, embodiments enable different and/or additional calibration operations and/or tests to be performed when compared with conventional loopback configurations.
