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.

[ What is claimed is:] [1.] A process for programming a programmable logic device (PLD) with a plurality of row patterns, the process comprising the steps of:finding a basis set for the row patterns using Boolean operations, the basis set including a plurality of patterns selected such that each of the row patterns is either a pattern in the basis set or derivable from one or more of the patterns in the basis set by performing Boolean operations;selecting one or more patterns in the basis set; andfor each selected pattern, programming simultaneously all rows of the PLD having a row pattern, which is either identical with the selected pattern or derivable from the selected pattern using Boolean operation.
