Abstract
Access is obtained to a truth table having a plurality of rows, each including a plurality of input bits and a plurality of output bits. At least some rows include don't-care inputs. At least some of the rows are clustered into a plurality of multi-row clusters. At least some of the multi-row clusters are assigned to ternary content-addressable memory modules of a prefabricated programmable memory array. Instructions for interconnecting the ternary content-addressable memory modules with a plurality of input pins of the prefabricated programmable memory array and a plurality of output pins of the prefabricated programmable memory array are specified in a data structure, in order to implement the truth table.
