  • Publication number: 20210173010
    Abstract: A method of identifying error patterns during automated device testing comprises receiving a data pattern from a plurality of capture modules programmed on a programmable logic device, wherein the plurality of capture modules are programmable and operable to selectively capture data traffic to be monitored, and wherein the data traffic comprises a flow of traffic between a DUT and the programmable logic device. The method further comprises comparing the data pattern with known signatures in an error signature database. Also, the method comprises correlating the data pattern with one or more matching known signatures in the error signature database and assigning a score to each of the one or more matching known signatures in the error signature database based a level of correlation.

  • Patent number: 10592370
    Abstract: A system for performing an automated test is disclosed. The method comprises programming a application programming interface (API) to control a default production flow on a tester, wherein the production flow comprises a plurality of test sequences associated with executing tests on devices under test (DUTs) connected to the tester. The method further comprises configuring the API to modify the default production flow to customize the plurality of test sequences in accordance with a user-specific API, wherein the user-specific API comprises a modification to the production flow in accordance with testing requirements of a user. Finally, the method comprises integrating the user-specific API with the API to customize the API for the user.

  • Patent number: 10557886
    Abstract: A system for performing an automated test is disclosed. The system comprises a first user computer operable to load a first test plan from a first user to a control server and a second user computer operable to load a second test plan from a second user to the control server. The system further comprises a tester comprising at least one rack for deploying a plurality of primitives. The control server is communicatively coupled to the first user computer, the second user computer and to the tester, wherein the control server is operable to allocate a first subset of primitives to the first test plan and manage execution of the first test plan on the first subset of primitives, and also operable to concurrently allocate a second subset of primitives to the second test plan and manage execution of the second test plan on the second subset of primitives.
