Method and apparatus for performing testing of interconnections

Abstract

The present invention provides a method and apparatus configured to allow testing of interconnections between components in a system. The present invention utilizes a source of a known pattern, for example a pattern buffer, in a first component of the system and a capture buffer located in a second component of the system.

1 . A method for performing testing of an interconnect between components of a system comprising the steps of: 
 loading a first pattern into a controller pattern buffer of a controller;    transmitting the first pattern to a component of the components;    capturing the transmitted first pattern in a component capture buffer of the component;    performing a first comparison to compare the captured first pattern to the first pattern; and    identifying any interconnect faults based on the first comparison.
