Currently, several kilometers of interconnects are used to construct a state-of-the-art Si-based integrated circuit, which has up to 8 levels of metallization. The failure mechanisms and reliability of the different layers of metallization are assumed to be the same in circuit-level reliability analysis. Although this may be true in Al interconnects, it may not be so for Cu dual-damascene lines. In this paper, we report on differences in the failure mechanisms between the first (M1) and second (M2) levels of Cu metallization, and how it affects the overall circuit reliability for Cu metallization.
Decision tree induction corresponds to partitioning the input space through the use of internal nodes. A node attempts to classify the instances misclassified by upper level nodes using a greedy search strategy, i.e. ...

Recent advances in computer arithmetic offer interesting alternative solutions for low-power design. Depending on an assortment of factors that need to be considered, it is worth evaluating the logarithmic number system (LNS) or the residue number system (RNS) for hardware implementations of computationally intensive tasks. As such, the choice of arithmetic can lead to substantial power savings.

We present the embedded trees algorithm, an iterative technique for estimation of Gaussian processes defined on arbitrary graphs. By exactly solving a series of modified problems on embedded spanning trees, it computes the conditional means with an efficiency comparable to or better than other techniques. Unlike other methods, the embedded trees algorithm also computes exact error co-variances. The error covariance computation is most efficient for graphs in which removing a small number of edges reveals an embedded tree. In this context, we demonstrate that sparse loopy graphs can provide a significant increase in modeling power relative to trees, with only a minor increase in estimation complexity.
