Energy-and-performance efficient differential domino logic cell libraries for QDI-model-based asynchronous circuits

QDI-model-based asynchronous circuits which contain differential domino logic (DDL) circuits are promising implementation against random delay variations. A physical DDL cell can represent all the family functions without extra gates since it is based on the dual-rail encoding. This paper proposes a physical DDL library which only contains 12 cells and three logical synthesis libraries for this physical DDL library. In this paper, some evaluation results are shown using the Nangate 45nm process technologies. As a result, it can be concluded that the proposed three synthesis libraries can generate energy-and-performance efficient circuits using the appropriate synthesis tools.
