Generalized symmetric variables
Malgorzata Chrzanowska-Jeske · 2002
Symmetric variables have been used extensively to simplify design and synthesis of digital circuits. Methods to detect symmetric variables as well as special methods for synthesis and design of highly symmetric functions have been continuously investigated. In this paper the author identifies and describes new, generalized symmetric relations between variables of Boolean functions. A method to detect and identify these symmetries is presented, and results showing the existence of such symmetries in MCNC benchmark functions are given. Possible applications are discussed.
