ABSTRACT:
The method for mapping a logic circuit to a plurality of interconnectable, programmable look up tables (LUT) elements includes forming logic element groups including individual logic elements and/or previously formed logic element groups that are capable of being accommodated within the fanin and/or fanout capacity of a target LUT. The method further includes mapping the formed logic element group to the target LUT, and repeating the process for forming logic element groups and mapping to target LUTs for the entire network in a manner such that at each stage only the unmapped logic element/elements and mapped logic element groups of the previous stage are considered for mapping.
