Abstract: A method for monitoring communications between a device under test (DUT) and an automated test equipment (ATE) is disclosed. The method comprises programming an interface core and a protocol analyzer module onto a programmable logic device, wherein the programmable logic device is controlled by a system controller and is operable to generate commands and data to test a DUT, wherein the interface core is operable to generate signals to communicate with the DUT using a protocol associated with the DUT. The method also comprises monitoring data and command traffic associated with the protocol in the interface core using the protocol analyzer module and storing results associated with the monitoring in a memory comprised within the protocol analyzer module. The method finally comprises transmitting the results upon request to an application program associated with the protocol analyzer module executing on the system controller.

Abstract: A method for receiving data using an FPGA receiver circuit comprises receiving payload data from a DUT using a first rate of a plurality of line rates during a first burst, wherein the DUT is communicatively coupled to the FPGA receiver circuit. The method further comprises transitioning to a power saving state at an end of the first burst and receiving synchronization data from the DUT using a second rate of a plurality of line rates during a second burst. Further, the method comprises establishing synchronization with a clock data recovery (CDR) circuit of the FPGA receiver circuit at the second rate and receiving payload data from the DUT at the second rate.
