Characterization and hardware correlation of multi-gigahertz parallel bus with transmit pre-emphasis equalization

This work describes the characterization and hardware correlation of an equalized parallel bus for multi-gigahertz data-rate operation. In contrast to our earlier paper where interconnect design, modeling, and equalization of band-limited channels were discussed, This work focuses on characterization and correlation methodologies of complete passive and active chip-to-chip communication systems. The simulation and measurement results of equalized channels are correlated in both time and frequency domains. The performance of equalized channels is also verified by comparing the measured and simulated eye diagrams for various values of equalization coefficients up to 8 GHz data rates.
