Abstract(in Japanese) (See Japanese page)
Abstract(in English) We have proposed a cell-based design methodology or rapid single flux quantum (RSFQ) logic circuits based on the binary decision diagram (BDD). To makea cell library we add one-junction Josephson transmission line (JTL) at input and output nodes of each cell as a buffer circuit, by which no deterioration of the DC bias margin is observed for the connection of each cell. In thelayout level, the size, and the position and the width of the input/outputinductor of each cell are equalized. We have designed 1 bit half adder using the BDD RSFQ cell library and shown that the cell-based design is superior to the custom design in respect of robustness and modularity of the circuit.
