Chip layout design of a Josephson LSI circuit for examining high-speed operability by using a standard cell automatic placement and routing technique

摘要

A chip layout design technique for a high-speed Josephson LSI circuit using an automatic placement and routing technique with a standard cell method has been developed. A chip layout design of a Josephson LSI circuit with 1500 gates for examining high-speed operability with a 1 GHz clock frequency has been successfully obtained. Related to high-frequency power on a high-speed Josephson LSI circuit, a dividing method for a circuit and a balancing method for power loads are proposed.
