Abstract

A bus tuning system is provided for determining the configuration of an electronic device and for testing and tuning a bus system of the electronic device specifically for its configuration, the bus system including a bus interface coupled with a bus characterized by a number of parameters. The system has a mechanism for determining the configuration of the electronic device; a mechanism for injecting a set of stimulus patterns on the bus; a mechanism for collecting information regarding operation of the electronic device corresponding to the stimulus patterns, including information identifying any error resulting from the set of stimulus patterns; a mechanism for comparing the collected information with information corresponding to the configuration of the electronic device; a mechanism for determining, responsive to the comparing mechanism, whether the electronic device is operating within a predetermined set of operating specifications; and a mechanism for adjusting values of one or more of the parameters by varying one or more electronic characteristics of the bus interface in response to a set of digital control signals to obtain a set of operating and signaling parameters of the bus interface that cause the electronic device to operate within the predetermined set of specifications.
