Abstract :
A synchronous latency-insensitive design (SLID) method that mitigates unknown on-chip global wire delays and removes the need for controlling global clock skew is presented. An SLID-based 5.4mm-long on-chip global bus, fabricated in a standard 0.18mum CMOS process, supports 3Gb/s/wire and accepts plusmn2 clock cycles of data-clock skew. This paper focuses on data synchronization for large global on-chip signals, which has become a difficult issue in high-frequency processor designs
