H-DFT: A Hybrid DFT Architecture For Low-Cost High Quality Structural Testing
نویسندگان
چکیده
This paper describes a Hybrid DFT (H-DFT) architecture for low-cost, high quality structural testing in the high volume manufacturing (HVM) environment. This structure efficiently combines several testing and test data compression approaches to enable application of a huge amount of ATPG and Weighed Random-BIST (WR-BIST) patterns. Results obtained from the application of the H-DFT technique to industrial designs demonstrate significant savings in test cost in terms of test data volume and test application time without compromising test quality. Implementation of the HDFT architecture on Intel ASIC and microprocessor designs are described.

Test Challenges of Nanometer Technology
DFT. The last 30 years have demonstrated that short time-to-market, low cost, and high product quality can only be achieved if test is part of the design and optimized for manufacturing. Structural DFT methodologies based on scan with voltage-based test, supplemented by Iddq test, provided predictable test quality and a basis for automation of test synthesis and test pattern generation. Scan al...

متن کاملVLSI Architecture for the Low-Computation Cycle and Power-Efficient Recursive DFT/IDFT Design
In this paper, we propose one low-computation cycle and power-efficient recursive discrete Fourier transform (DFT)/inverse DFT (IDFT) architecture adopting a hybrid of input strength reduction, the Chebyshev polynomial, and register-splitting schemes. Comparing with the existing recursive DFT/IDFT architectures, the proposed recursive architecture achieves a reduction in computation-cycle by ha...
متن کاملA hybrid density functional theory (DFT) and ab initio study of α-Acyloxycarboxamides Derived from Indane-1, 2, 3-trione
α-acyloxycarboxamides are synthesized from three component Passerini reaction between indane-1,2,3-trione, isocyanides, and thiophenecarboxylic acids in quantitative yields. The structures of the final products were confirmed by IR, 1H and 13C NMR spectroscopy, mass spectrometry, and elemental analysis. The B3LYP/HF calculations for computation of 1H an...
