N2 - Based on the effective attenuation constant approximation of distributed RLC lines, simplified design guidelines are presented dealing with the line characteristics, termination, and delay estimation of on-chip global interconnects. RC delay models are verified to be still accurate for a wide range of parameters conventionally considered inductive. A new closed-form RLC delay formula is developed when RC models are inadequate. The formula works for both voltage and current-mode signaling and exhibits 10% accuracy of SPICE simulation. This work is suitable for global routing topologies and iterative layout optimization.
