摘要

The performance of high-end routers will soon reach the limits of conventional technology. Single flux quantum (SFQ) digital technology is a key technology for achieving a breakthrough. We have already proposed a high-end router using SFQ technology. In this paper, we report on the latest innovation of SFQ router technology. First we describe a design methodology development. We have developed a new SFQ logic cell library for cell-based top-down circuit design. To expand the circuit scale further, a novel pseudo-automatic Josephson transmission line (JTL) routing technique has also been developed. And then, we discuss issues of passive interconnection, and show the operation of a passive transmission line interconnected circuit up to 40-Gbps throughput. Second we describe a packet switch circuit demonstration. We designed a 2 x 2 crossbar packet switch circuit, which is a key element in the packet switch. We successfully tested the circuit up to a clock frequency of 35 GHz. Finally we discuss an SFQ circuit application in the optical router as an alternative application strategy.
