Full-custom design is considered superior to standard-cell design when a high-performance circuit is requested. The structured routing of critical wires is considered to be the most important contributor to this performance gap. However, this is only true for bitsliced designs, such as ripple-carry adders, but not for designs with inter-bitslice interconnections spanning several bitslices, such as tree adders and reduction-tree multipliers. It is found that standard-cell design techniques scale… CONTINUE READING
