  • Publication number: 20090115443
    Abstract: Embodiments of a system and method for testing an integrated circuit module comprising multiple integrated circuit devices, such as a memory module comprising multiple memory devices for example, is disclosed. Embodiments of the method may be employed to test an integrated circuit device of the integrated circuit module that provides a data strobe signal associated with at least one data signal provided by the same integrated circuit device. A determination of a test outcome for the integrated circuit module may be made after identifying data valid windows for each integrated circuit device, without having to both identify a common sampling window defined by an intersection of the identified data valid windows and verify that such common sampling window meets specification requirements, as may be performed by conventional testers.

  • Publication number: 20080301509
    Abstract: Embodiments of an apparatus and method for high-speed testing of a device under test are described herein, where the device under test is coupled to a tester via a limited passband communication channel. A plurality of test vector patterns is generated having characteristics such that when a given test vector pattern is transmitted electrically at a transmission rate via the communication channel, the test vector pattern has a frequency content that is less than the frequency content of a high frequency test vector pattern if the high frequency test vector pattern were to be transmitted electrically at the transmission rate via the communication channel, and such that the frequency content of each test vector pattern when transmitted electrically at the transmission rate via the communication channel falls within the passband associated with the communication channel.
