This paper addresses the design challenges of simulating the 3-D vertical-resistive random access memory (V-RRAM) toward MB-level. The interconnect IR drop and sneak paths are known to be the limiting factors for building large-scale V-RRAM arrays. The previous approach to evaluate the write/read margin of V-RRAM was based on the exhaustive SPICE simulations, which prohibits the design exploration...
A simulation model of crowd evacuation based on the cellular automata is introduced. The implementation on GPU is focused in details. This model takes advantage of GPU to complete part of computing by certain allocation. Taking Guangzhou Tianhe stadium as an example, the model shows that the performance of computing has been significantly improved by parallel computing technique of GPU, which obtained...
Forest evolution simulation and visualization are challenging tasks in terms of complex interactions at various time and space scales. In this paper we present a forest evolution simulator system, based on individual-based, spatially explicit forest gap model, incorporating with fine-scale process of neighbor competition and understory recruitment. The forest evolution for each growth cycle is visualized...
In order to cope with the problems of disfluency and slow respondence of computer when processing large volume of point cloud, the paper proposes an solution based on virtual memory technology, valid data structure, effective algorithms and OpenGL technology and so on to quickly and accurately build 3d model. The above research is implemented by VC++ 6.0 program language and OpenGL 3D graphic library...
A system the final goal of which is to design feelings of fabrics has been developed. For this purpose, cloth was modeled based on thread model and geometrical arrangement of threads of cloth. A simulation system was constructed with the cloth model. In the system, a lot of calculating time is required when wide range of cloth is treated. The system was accelerated with a Cell/B.E. processor. By SIMD...
To facilitate training of biological cell injection operations, we are developing an interactive virtual environment to simulate needle insertion into biological cells. A key challenge of deformable simulation is to satisfy the conflicting requirements of real-time interactivity and physical realism. This paper presents methodologies for dynamic modeling, visual/haptic display and model validation...
We present a practical, systematical method for the evaluation of the soft error rate (SER) of microelectronic devices. Existing methodologies, practices and tools are integrated in a common approach while highlighting the need for specific data or tools. The showcased method is particularly adapted for evaluating the SER of very complex microelectronic devices by engineers confronted to increasingly...
With the event of nanoscale technologies, new physical phenomena and technological limitations are increasing the process variability and its impact on circuit yield and performances. Like combinatory cells, the sequential cells also suffer of variations, impacting their timing characteristics. Regarding the timing behaviors, setup and hold time violation probabilities are increasing. This article...
