This paper presents a case study of the modeling and simulation methods used to design the signal path for a proposed 80-Gbps serial data link between digital systems. This design includes flip-chip transitions from custom IBM 8HP integrated circuits to multilayer organic substrates, with coaxial-cable connections between substrates. Discussion topics include interconnect material selection, detailed 3-D electromagnetic modeling of the conductor transitions and signal paths, time-domain circuit simulation of the complete data path including the driver and receiver, and bit-error rate analysis of the complete link. Simulated data are presented.
