Abstract
VLSI technology scaling raised the new problems in conventional metal wires. Some new technologies and materials are proposed for modern interconnects such as optical interconnection, Nano-wires and radio frequency interconnection. In this paper, a new placement/planning approach is proposed for using the RF interconnects in regular ASICs. In the proposed approach, three placement configurations are examined for RF resources and electrical characteristics of the final circuit is compared. Our experimental results show that using a suitable RF planning, this technology can be suitable, especially for large and complex circuits. Approaches examine the best and suitable placement for RF interconnections making better slacks in paths and smaller total wire length in plan. In this work, three approaches for RF interconnection placements are proposed. Experimental results show that performance of attempted circuit can be improved by about 19% in cost of less than 5% area overhead.
