Abstract:
A testing method for testing a bus system of an electronic device, the bus system including a bus interface coupled with a bus characterized by a number of parameters, the testing method comprising:(a) determining the configuration of the electronic device; (b) injecting a set of stimulus patterns on the bus; (c) 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; (d) comparing the collected information with information corresponding to the configuration of the electronic device; (e) determining, responsive to the comparing step, whether the electronic device is operating within a predetermined set of operating specifications; and (f) 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.
