Abstract
A method of circuit design may include identifying, using a processor, a timing critical path within a first look-up table structure in a circuit design and restructuring, using the processor, the first look-up table structure into a functionally equivalent second look-up table structure. The second look-up table structure may include fewer look-up tables serially coupled in the timing critical path than the first look-up table structure. The method may include placing, using the processor, the second look-up table structure and routing, using the processor, the second look-up table structure.
