Gates and circuits in conventional digital electronics do not facilitate regeneration of the inputs from their outputs and hence they are termed as irreversible. Another issue of concern with the conventional digital electronics is heat dissipation. These challenges in traditional digital electronics can be overcome by using reversible logic. Logical reversibility is also strongly associated with quantum computing. This chapter intro- duces to reversible logic, quantum gate library and some popular reversible gates. It also presents example of reversible circuit. The performance parameters popularly used to analyse reversible logic are discussed and their computations are presented with examples. Finally, a brief introduction to HSPICE simulation tool is included along with the logic synthesis parameters. The Concept of Reversibility The basic building blocks of digital circuit are logic gates. In traditional digital electronics, although the gates can have more than one inputs, they have only one output. For example, the basic OR, AND, NAND or XOR has two inputs and one output.
