Advantest Assigned Patent
Testing CXL enabled devices in parallel
By Francis Pelletier | January 23, 2025 at 2:33 pmAdvantest Corporation, Tokyo, Japan, has been assigned a patent (12197303) developed by Malisic; Srdjan, and Yuan; Chi, San Jose, CA, for “systems and methods for testing CXL enabled devices in parallel“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “Efficient and effective testing systems and methods are presented. In one embodiment, a test system includes: a user interface configured to enable user interaction with the system; a test board configured to communicatively couple with a plurality of devices under test (DUTs), wherein the DUTs are compute express link (CXL) protocol compliant; and a tester configured to direct testing of the plurality of DUTs, wherein the tester manages testing of the plurality of DUTs, including managing flexible and independent parallel testing across the plurality of DUTs. In one exemplary implementation, the tester generates and manages workloads independently for DUTs included in the plurality of DUTs. The DUTs can be memory devices the tester is configured to test different memory spaces in parallel. The different memory spaces can have various implementations (e.g., included in the plurality of DUTs, different memory spaces are within one of the DUTs included in the plurality of DUTs, etc.). Workloads can be generated based upon individual characteristics of the DUTS and managed separately. The testing can include performance testing. (e.g., bandwidth testing, latency testing, error testing, etc.).”
The patent application was filed on 2023-03-31 (18/129414).
