Jitter modeling in statistical link simulation

Modern high-speed I/O link design requires accurate modeling and simulation of various jitter types including both deterministic and random jitter components. Transient simulators such as SPICE have successfully modeled deterministic jitter but they have limited capabilities to model random jitter. A statistical approach has been recently employed to handle jitter more efficiently. This paper presents a general jitter model suitable for a statistical simulation framework. The proposed model can accurately account for transmitter and receiver random jitter with any distribution and power spectrum density. We have also extended the proposed model to derive a closed-form formula for modeling transmitter clock jitter. The presented methodology is validated using both time-domain simulation and lab measurement.
