Abstract
A HASS testing system provides for testing and tuning of a bus system of an electronic device having a bus interface coupled with a bus characterized by a number of parameters. The HASS testing system includes a mechanism embedded in the device for injecting a set of stimulus patterns on the bus; a mechanism embedded in the device 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 corresponding information collected during baseline testing; a mechanism for determining, from the comparing step, whether the device is operating within a predetermined set of operating specifications; and a mechanism embedded in the device 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 is cause the device to operate within the predetermined set of specifications.
