Abstract

In one embodiment of the invention, an integrated circuit (IC) design tool is provided for synthesizing logic, including one or more software modules to synthesize a gate-level netlist of a squarer functional block. The software modules include a bitvector generator, a bitvector reducer, and a hybrid multibit adder generator. The bitvector generator multiplies bits of a vector together to generate partial products for a plurality of bitvectors and then optimizes a plurality of least significant bitvectors. The bitvector reducer reduces the partial products in the bitvectors of the squarer functional block down to a pair of final vectors. The hybrid multibit adder generator generates a hybrid multibit adder including a first adder and a second adder coupled together by a carry bit with bit widths being responsive to a dividerbit. The hybrid multibit adder adds the pair of final vectors together to generate a final result for the squarer functional block.
