Optimal synthesis of differential cascode voltage switch (DCVS) logic circuits using ordered binary decision diagrams (OBDDs)

Abstract

This paper presents a method for near-optimum synthesis of Differential Cascade Voltage Switch (DCVS) logic circuits using Ordered Binary Decision Diagrams (OBDD). The method presented produces efficient DCVS circuit structures in terms of transistor count which positively affects the circuit area and performance. The proposed method is also very practical because it produces results with short run-times on a design workstation. The paper presents experimental results that demonstrate the use and the efficiency of the proposed DCVS synthesis method. This method is the basis for a CAD tool that allows automatic synthesis of fault secure circuits based on the DCVS technology.
