Transition Skew Coding for Global On-Chip Interconnect
This paper presents new simulation results of the previously proposed transition skew coding (TSC) for global on-chip interconnects. Considering 2-GHz global clock frequency at the 90-nm node, we show that TSC can be applied to broad range of wire length on both semiglobal and global metal layers, while maintaining its energy efficiency and its advantages in terms of crosstalk reduction and signal integrity, and wiring and repeater area minimization.
