Abstract

In this paper, we propose a new framework to synthesize rapid single flux quantum (RSFQ) logic circuits. In our framework, we construct a virtual cell, which we call "2-AND/XOR," from the RSFQ logic primitives. By using 2-AND/XOR cells, we can successfully adopt the conventional logic design techniques into our framework, and thus we can successfully generate RSFQ circuits in reasonable time even for large benchmark circuits that have not been reported in the existing researches.
