A new approach to synthesis of permutation class of quantum logic circuits has been proposed in this paper. This approach produces better results than the previous approaches based on classical reversible logic and can be easier tuned to any particular quantum technology such as nuclear magnetic resonance (NMR). First we synthesize a library of permutation (pseudobinary) gates using a Computer-...

Equivalence Classes of Circuit Mutants for Experimental Design Debabrata Ghosh Franc Brglez CBL (Collaborative Benchmarking Lab), Dept. of Computer Science, Box 7550 NC State University, Raleigh, NC 27695, USA http://www.cbl.ncsu.edu/ Abstract { Experimental Design, as de ned in science and manufacturing, relies on data sets that belong to well-de ned equivalence classes.

A systematic method for the generation of variable gain amplifier topologies is proposed. The generation is based on voltage controlled current sources (VCCSs) modelling saturated MOS transistors, resistors or combinations of these elements. It is shown that many alternative circuit topologies can be generated, that would not easily have been found in an intuitive way. Simulation results shown ...

This paper describes a training and research tool for learning basic issues related to BIST (Built-In SelfTest) generator. The main didactic aim of the tool is presenting complicated concepts in a comprehensive graphical and analytical way. The paper describes a computer-aided design (CAD) that is used to generate automatically the BIST to any digital circuit. This software technique attempts t...

A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power, improved noise and electromagnetic compatibility (EMC) properties, and a natural match with heterogeneous system timing. In this overview article each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives,...

State-of-the-art TCAD software like the multi-dimensional device and circuit simulator MINIMOSNT require a huge amount of information in addition to the device input data to control several different complex modules and tasks. This information is normally hierarchically structured containing arbitrary cross-relations and dependencies that include, e.g., material properties, circuit descriptions...

We present a novel methodology for characterization of sub-quartermicron CMOS technologies. It involves process calibration, device calibration employing twodimensional device simulation and automated Technology Computer Aided Design (TCAD) optimization, and, finally, transient mixed-mode device/circuit simulation. The proposed methodology was tested on 0.25 m technology and applied to 0.13 m t...

This paper addresses several issues involved for routing in Field-Programmable Gate Arrays (FPGAs) that have both horizontal and vertical routing channels, with wire segments of various lengths. Routing is studied by using CAD routing tools to map a set of benchmark circuits into FPGAs, and measuring the effects that various parameters of the CAD tools have on the implementation of the circuits...
