    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1483 KB)

    A localized parametric time-sheared Gabor atom is derived by convolving a linear frequency modulated factor, modulating in frequency and translating in time to a dilated Gaussian function, which is the generalization of Gabor atom and is more delicate for matching most of the signals encountered in practice, especially for those having frequency dispersion characteristics. The time-frequency distr... View full abstract»

  • Low overhead design-for-testability for scan-based delay fault testing

    Publication Year: 2007, Page(s):40 - 44
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (815 KB)

    An efficient design-for-testability (DFT) technique is proposed to achieve low overhead for scan-based delay fault testing. Existing techniques for delay test such as skewed-load or broadside make the test generation process complex and produce lower coverage for scan-based designs as compared with non-scan designs, whereas techniques such as enhanced-scan test can make the test easy but need an e...
