Carbon nanotube bundle interconnect: Performance evaluation, optimum repeater size and insertion for global wire

To remove the bottleneck of the interconnect especially at semi-global and global level, performance evaluation of local, semi global, and global interconnect is presented in this paper based on carbon nanotube (CNT) interconnect bundle model. For the greater length of the wire, a methodology is presented to find the optimum insertion and size of buffer for CNT bundle interconnects. The performance analysis for repeater shows that the CNT bundle can run 2.58 times longer without repeater insertion and requires 31% less buffer size than Cu wire.
