Patent number: 12203978Abstract: Presented embodiments facilitate efficient and effective flexible implementation of different types of testing procedures in a test system. In one embodiment, a flexible sideband support system comprises a load board, testing electronics coupled to the load board, a controller coupled to the testing electronics. The load board is configured to couple with a plurality of devices under test (DUTs), wherein the load board includes in-band testing ports and sideband testing ports. The testing electronics is configured to test the plurality of DUTs, wherein a portion of testing electronics are organized in sideband resource groups. The controller is configured to direct testing of the DUTs, wherein the controller is coupled to the testing electronics and the controller directs selective allocation of the testing electronics in the sideband resource groups to various testing operations of the DUTs.Type: GrantFiled: August 15, 2023Date of Patent: January 21, 2025Assignee: Advantest CorporationInventors: Srdjan Malisic, Chi Yuan, Seth Craighead

Patent number: 11714132Abstract: Presented embodiments facilitate efficient and effective diagnostic of test system operations, including temperature control of test equipment components. In one embodiment a test equipment diagnostic method includes applying a known/expected first bit pattern to a test equipment component, applying a known/expected second bit pattern to a test equipment component, and performing a test equipment temperature control analysis based upon the results of applying the known/expected first bit pattern and known/expected second bit pattern. The first bit pattern and second bit pattern have known/expected respective thermal loads and corresponding respective first known/expected/expected temperature and second known/expected/expected temperature. In one embodiment, performing a test equipment temperature control analysis includes determining if temperature control components control a temperature of the test equipment component within acceptable tolerances.Type: GrantFiled: March 31, 2021Date of Patent: August 1, 2023Assignee: Advantest CorporationInventors: Mei-Mei Su, Seth Craighead

Patent number: 11619667Abstract: Presented embodiments facilitate efficient and effective flexible implementation of different types of testing procedures in a test system. In one embodiment, a tester system diagnostic method includes forwarding test signals to a loopback component; receiving the test signals from the loopback component; and analyzing the test signals to diagnose whether or not the test system is experiencing problems associated with electrostatic discharges, including analysis of eye scan configuration data corresponding to characteristics of the test signals. In one exemplary implementation, analyzing the eye scan configuration data, including analyzing symmetry of a graphical representation (e.g., eye pattern, eye diagram, etc.) of the eye scan configuration data with respect to a horizontal graphical representation axis.Type: GrantFiled: March 8, 2021Date of Patent: April 4, 2023Assignee: Advantest CorporationInventors: Mei-Mei Su, Seth Craighead
