Claim 18:
19. A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed, cause one or more processors to:
provide user-selectable options for a test device that is configured to establish a multi-lane high speed input/output (I/O) link of a device under test (DUT) and to assess an electrical margin of one or more lanes of the multi-lane high speed I/O link in either or both transmit (Tx) and receive (Rx) directions, the user-selectable options including customizations for assessment of the electrical margin of the one or more lanes of the multi-lane high speed I/O link;
receive a selection of one or more of the user-selectable options for the test device; and
initiate performance by the test device of an assessment of the electrical margin of the one or more lanes of the multi-lane high speed I/O link based on the selection of the one or more of the user-selectable options for the test device,
wherein performance of the assessment of the electrical margin includes:
establishing, by the test device, the multi-lane high speed I/O link of the DUT in which, for the one or more lanes of the multi-lane high speed I/O link, a controller coupled to at least one interface in the test device implements physical and logical link layers that communicatively connect a margin test transmitter and/or a margin test receiver of the test device with the DUT via the at least one interface; and
under control of the controller, causing the margin test transmitter and/or margin test receiver to inject a signal or adjust a timing of a signal communicated between the DUT and the test device via the multi-lane high speed I/O link to assess the electrical margin of the one or more lanes of the multi-lane high speed I/O link in either or both the Tx and Rx directions wherein the controller causes the margin test transmitter to transmit data in the Tx direction to the DUT, and the margin test receiver receives data in the Rx direction from the DUT.
