RF resource planning in application specific integrated circuits to improve timing closure

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, nanowire technology 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.
