Low-Power Repeater Insertion for Global Interconnects
Repeater insertion is one of the most widely used techniques to reduce the signal propagation delay on global interconnects. The number of repeaters inserted into interconnects is expected to be enormous due to the ever-increasing chip dimension. The huge number of repeaters can take up significant …
