A B S T R A C T : MINIMOS, the Viennese two-dimensional MOS device simulation program, has been under development for almost seven years. The features of the most recent version of MINIMOS are described with particular regard to the implemented physical models. Some of the presently used numerical techniques are commented. An example demonstrates the capability of MINIMOS to tackle ULSI simulat...

Several 64-bit adders have been designed and their ezpected yield has been estimated. OUT Tesults show that the yield of VLSI adders can be improved by modifying the layout of the ol.iginal design and/or by choosing a dzfferent layout and circuit structure. In certain situations, these approaches can improve the yield by 10% to 17%.

We study the structure of the load-based spanning tree (LST) that carries the maximum weight of the Erdös-Rényi (ER) random network. The weight of an edge is given by the edge-betweenness centrality, the effective number of shortest paths through the edge. We find that the LSTs present very inhomogeneous structures in contrast to the homogeneous structures of the original networks. Moreover, it...

In the late 90's, the National Research Council sponsored work on a scholarly history of the development of computer technology during the 80's. The results were published in 1999 in the book Funding a Revolution, which reveals how close government-universityindustry interactions jointly supported rapid progress in new areas of computing, noting in particular the key role of the Defense Advance...

Spike-timing dependent synaptic plasticity (STDP) circuitry is designed in 0.35μm CMOS VLSI. By setting different circuit parameters and generating diverse spike inputs, we got different steady weight distributions. Through analysing these simulation results, we show the effect of membrane threshold and input rate in STDP adaptation.

Low power has emerged as a principal theme in today’s electronics industry. The need for low power has caused a major paradigm shift where power dissipation has become as important a consideration as performance and area. This article reviews various strategies and methodologies for designing low power circuits and systems. It describes the many issues facing designers at architectural, logic, ...

The embedding problem for a class of graphs called rectilinear graphs is discussed. These graphs have applications in many VLSI Layout Problems. An interesting topological characterization of these graphs lead to efficient algorithms for recognizing and embedding rectilinear graphs which are embeddable on the plane.

It is widely agreed that the design methods and computer support of VLSI design are generally more mature than those of mechanical items. Why is this so, and is there any hope of the gap being significantly closed? This paper argues that there are fundamental reasons, that is, reasons based on natural phenomena, that keep mechanical design from approaching the ideal of VLSI design methods. The ...
