Abstract
A process for efficiently programming a programmable logic device (PLD) is provided. A basis set for a desired matrix of programming pattern ('pattern matrix') is a set of row patterns from which all the row patterns of the pattern matrix can be derived by applying a Boolean operation on two or more row patterns of the basis set. The disclosed process derives a minimal basis set, i.e., a set with the smallest number of row patterns among basis sets for the given pattern matrix.
