The method to insert observation points by replacing cells is proposed for laser voltage probing (LVP) measurements to ease failure analysis. Also proposed are a model of delay change with placing observation points and its insertion procedure that minimizes the number of timing violations. Evaluation in a commercial product circuit shows that ??replacement-type?? observation points can be inserted...
Scientific data processing and visualization of computational simulation data have played an important role in knowledge creation, and its transfer for the benefit of society, through scientific discovery and understanding of physical and chemical phenomena. Massively parallel processing architecture has greatly contributed to increase the computational power and to enlarge the scale of computation...
In this paper, we introduce a novel point-based volume rendering technique based on tiny particles. In the proposed technique, a set of tiny opaque particles is generated from a given 3D scalar field based on a user-specified transfer function and the rejection method. The final image is then generated by projecting these particles onto the image plane. The particle projection does not need to be...
We have commonly employed medical images, not including X-ray photography, which have their image enhanced by taking advantage of certain characteristics of the human body to look for some valuable medical information. In general, the medical imaging modalities have employed an image acquisition method which enhances a certain feature of the seat of a disease for later processing of the acquired images...
We propose a hierarchical parameter optimization technique which further enhances our original technique for an accurate biological cell simulation. Our original technique generates a k-d tree and uses the coefficient of multiple determination (R2) for tree-branching, however it requires a huge computation time since it processes the response surface at every leaf node of the k-d tree, including those...
