Structured ASICs (sASICs) have received a lot of attention in the media as a means of keeping the non-recurrent design engineering costs down. This paper describes the experiences of a collaborative research project between Infineon Technologies and Synopsys Inc. over the last year. We discuss a design flow based on standard Synopsys tools and a custom executable to implement sASIC blocks. We p...

Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...

Analysts, scientist, engineers, and multimedia professionals require massive processing power to analyze financial trends, create test simulations, model climate, compile code, render video, decode genomes and other complex tasks. Although these groups could use specialized super computers, the custom development time and the hardware costs are prohibitive. This paper describes how we applied t...

We report here specialized functions incorporated recently in the rigid-body docking software toolkit TagDock to utilize electron paramagnetic resonance derived (EPR-derived) interresidue distance measurements and spin-label accessibility data. The TagDock package extensions include a custom methanethiosulfonate spin label rotamer library to enable explicit, all-atom spin-label side-chain model...

The use of sensitive electronic equipment has increased now a days which has lead to power quality problems. The various power quality disturbances are transients, interruptions, voltage sag, voltage swell, voltage collapse, harmonics etc. To solve these power quality problems various custom power devices are used. Dynamic voltage restorer (DVR) is a custom power device used for the Compensatio...

In this paper, an electromagnetic transient model of Fixed Capacitor/ Thyristor Controlled Reactor (FC-TCR) is developed and applied to the study of transients due to load variations. The work is then extended to custom power equipment, namely Distribution Static Compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) aimed at enhancing the reliability and quality of power flows in low voltag...

The paper presents project of reprogrammable chip – FPGA, designed with current-mode gates novel digital gates operating with constant, continuous power supply current. Such continuous supply is a perfect one for analog-digital circuits, which are located on the same single die. Switching of digital part of the chip don’t disturb analog part. Based on the proposed approaches to minimizing logic...

The paper deals with the problem of designing mixed programmable analogue-digital circuits on a single die, and in particularly, with the problem of designing FPGA cells with current-mode gates novel digital gates operating with constant, continuous power supply current. Based on the proposed approaches to minimizing logic functions and designing digital current – mode circuits, the current-mod...

Power quality has become a very important issue recently due to the impact on electricity suppliers, equipment manufacturers and customers. Power quality is described as the variation of voltage, current and frequency in a power system. Voltage magnitude is one of the major factors that determine the quality of power. Indeed, custom power technology, the low-voltage counterpart of the more wide...

Through the administration and use of eXtremeTORC, HighTORC, TORC and the various other HPC clusters at Oak Ridge National Laboratory (ORNL), it quickly became apparent that a solution for the administration of federated clusters, or “clusters of clusters,” was needed. While a few cluster tools did exist when this work was started, there were none with the vision to handle multiple clusters as ...
