International Business Machines Corporation - Armonk NY
International Classification:
G01R031/28, G06F011/00, G06F007/02, H03M013/00
US Classification:
714/732000, 714/736000, 714/819000
Abstract:
A method for determining common failure modes of an integrated circuit device under test is disclosed. In an exemplary embodiment of the invention, a test pattern is applied to a series of inputs of the device under test. A set of output data generated by the device under test is then compared to a set of expected data, with the set of output data being generated by the device under test in response to the test pattern. It is then determined whether the set of output data has passed the test, with the set of output data passing the test if the set of output data matches the set of expected data. If the set of output data has not passed the test, then it is determined whether an output signature corresponding to the set of output data matches a previously stored output signature. Fail data corresponding to the output signature is then stored if the output signature matches a previously stored output signature.

International Classification:
G01K007/01
US Classification:
374/178000
Abstract:
A method and apparatus for providing a more accurate reading of the junction temperature within an Integrated Circuit (IC) where temperature sensing elements are used that are sensitive to process changes. The apparatus stores an offset value in the IC that is used by internal temperature reading circuitry to adjust the temperature read/calculated from the sensing elements to more accurately reflect the actual junction temperature.
