I also found this in an abstract (the actual paper isn't online):
A 3Gb/s/wire Global On-Chip Bus with Near Velocity-of-Light Latency
"We successfully show the practical feasibility of a purely electrical global on-chip communication link with near velocity-
of-light delay. The implemented high-speed link comprises a 5mm long, fully shielded, repeaterless, on-chip global bus reaching 3Gb/s/wire in a standard 0.18 µm CMOS process. Transmission-line-
style interconnects are achieved by routing signal wires in the thicker top metal M6 layer and utilizing a metal M4 ground return plane to realize near velocity-of-light data transmission. The nominal wire delay is measured to 52.8ps corresponding to 32% of the velocity of light in vacuum.
