Category: Circuit SimulationMay 1, 2008 Simulation accuracy is not a function of RELTOL settingIn SPICE, RELTOL determines convergence across iterations. Why then is it being touted by Berkeley Design Automation as a means of controlling simulation accuracy? Experienced SPICE users know that RELTOL is to accuracy as grapefruit spoon is to eye surgery. … April 28, 2008 Nascentric announces OmegaSim GX.Porting a multi-threaded SPICE simulator to a massively parallel GPU - interesting academic exercise or shape of things to come? March 28, 2008 Comments on multi-core HSPICE 2008.03 for post-layoutSynopsys recently announced a multi-core version of HSPICE (2008.03) that can handle, as well as pre-layout circuits, post-layout designs containing in excess of a million parasitic RCs. Prediction is a risky thing, but we called this a little while ago. … February 25, 2008 Circuit Simulation - the next generation?Drawing this series of circuit simulation articles to an end, we take a look at some of the vectors that are forcing change in the circuit simulation arena. Although predictions are inevitably risky and rarely correct, some areas ripe for … February 18, 2008 Circuit Simulation - the current state of playIn the handful of articles published to date on this site on the subject of circuit simulation, we’ve visited - briefly, at least - each of the three generations of circuit simulation stretching from the early 1970s to today. Nassda … February 11, 2008 Third generation circuit simulation - hierarchical simulationIn the second of these introductory computer simulation articles we covered Fast-SPICE, the second generation of circuit simulators. This article discusses the third generation of circuit simulation technology, the hierarchical tools, exemplified by HSIM. Initially aimed at the memory design and … February 5, 2008 Second generation circuit simulation - Fast-SPICEIn the first of these introductory articles on circuit simulation technology, we covered the initial generation of computer simulation software for transistor-level circuits, SPICE and its derivatives and descendents. This article focusses on the second generation of circuit simulators, examples … February 4, 2008 First generation circuit simulation - SPICE and derivativesAccurate circuit simulation technology is the very foundation of EDA and IC design. The modeling and simulation of circuits enables function and other operational characteristics to be obtained before committing the part to manufacture, let along before providing the part … |
