Abstract

Shigeru Yamashita will introduce a way to express functional flexibility by using sets of pairs of functions called "Sets of Pairs of Functions to be Distinguished" (SPFDs) rather than traditional incompletely specified functions.This method was very naturally derived from a unique concept for "distinguishing two logic functions," which will be explained in detail.

The flexibility represented by an SPFD assumes that the internal logic of a node in a circuit can be freely changed. SPFDs make good use of this assumption, and they can express greater flexibility than incompletely specified functions in some cases. Although the main subject of the talk is to explain the concept of SPFDs, Dr. Yamashita will also present an efficient method for calculating the functional flexibility by SPFDs. He will also make a comparison between SPFDs and compatible sets of permissible functions (CSPFs), which express functional flexibility by incompletely specified functions.

As an application of SPFDs, Dr. Yamashita will show a method to optimize LUT (look-up table) networks and experimental results.
