Editing Programmable logic array (section)

==Implementation procedure==

# Preparation in SOP ([[sum of products]]) form.
# Obtain the minimum SOP form to reduce the number of product terms to a minimum.
# Decide the input connection of the AND matrix for generating the required product term.
# Then decide the input connections of the OR matrix to generate the sum terms.
# Decide the connections of the inversion matrix.
# Program the PLA.
