Abstract
Genetic programming is applied to the synthesis of
arbitrary logic expressions. As a new method of logic
synthesis, this technique is uniquely advantageous in
its flexibility for both problem applicability and
optimization criterion. A number of experiments were
conducted exploring this method with different types of
logic gates and population sizes. While complete
function coverage is not guaranteed, the best
experimental test results over eight randomly designed
functions, of four to seven input variables, have
produced logic equations with a 98.4% function
coverage. In addition, the relation between the
training set size for the genetic program and function
coverage was also empirically explored. These
experiments showed that only small training sets were
necessary for function recognition.
