CAD Tool for Two-Digit Ternary Functions Design

Ternary number, which attracts the research attention for its high capacity, has emerged in many applications, recently. Unlike binary numbers, two bit ternary number involves 9³ = 729 different functions while two bit binary number involves only 4² = 16 different possible functions. In this paper, a novel automatic software description two bits ternary functions design tool is presented. Different examples are provided and synthesized to ternary logic circuits. Finally, the presented logic circuits are verified by SPICE simulation using carbon nano-tube (CNTFET) transistors.
