Research Abstract

The research focused on techniques to generate sets of basic circuit elements(cell libraries), which are essential to design large-scale single-flux-quantum(SFQ) digital circuits. The improved design guidelines to make reliable cells, including power supplying and the tradeoff between performance and power consumptions, were investigated. Several tools were developed for layout design toward automatic generation of wiring cells, which are dominant in cell libraries.
