Generation of high speed CMOS multiplier-accumulators

The authors describe MAGGEN (multiplier-accumulator generator), a technology-independent generator for high-speed CMOS Wallace-tree-based multiplier-accumulators (MACs). MAGGEN generates optimized netlists and compact layouts for MACs. MAGGEN's fast parallel MAC design is achieved through timing optimization routines. Compact layout, on the other hand, is achieved through prudent floorplanning, matched with placement optimization. MAGGEN is an integral tool set. In addition to netlist and layout, it generates all data files to allow the MACS to be used readily as megafunctions (netlist only) or megacells (netlist and layout) in larger designs.<
