Abstract
A 3D integrated circuit reduces delay when a signal traverses logical blocks of the integrated circuit. In one instance, the 3D integrated circuit has a first tier and a second tier including one or more first and second logical blocks, respectively. The first logical block(s) include a first primary output logic gate, a first primary input logic gate, a first primary input pin and a first primary output pin. The first primary output pin lies within a perimeter defined by a total area occupied by logic gates of the first logical block(s). The second logical block(s) include a second primary output logic gate, a second primary input logic gate, a second primary input pin and a second primary output pin. The second primary input pin is coupled to the first primary output pin.
