Application of Asymmetric Crosstalk Harnessed Signaling on 3D Hexagonal Interconnect Arrays

Abstract:
This paper describes a novel application of the Asymmetric Crosstalk Harnessed Signaling (ACHS) on 3D routing environments, where interconnect wires are distributed across the two dimensions perpendicular to the routing direction. The ACHS scheme completely eliminates the common encoding mode that is part of the original CHS scheme. A fully 3D multi-stripline stackup containing a wiring bundle in a hexagonal wire arrangement is applied where channels are placed together. Simulation results, that include crosstalk and jitter effects, have shown a significant performance improvement of ACHS over the original CHS scheme.
