Efficient Statistical Simulation of Intersymbol Interference and Jitter in High-Speed Serial Interfaces

We present and validate against experiments a modeling approach for high-speed serial links that combines the computational advantages of statistical techniques for intersymbol interference (ISI) (improved by employing the realistic pulse shape as from SPICE simulations) and a simple empirical methodology to account for the jitter of the transmitter. The proposed approach is validated by comparison with other modeling approaches such as full SPICE simulations (for ISI) and Simulink (for jitter) as well as against the experimental data for a 2.5 Gb/s CMOS differential transmitter driving different channels.
