Abstract

Differential signaling has been widely used in high-speed interconnects. Signal integrity issues, such as inter-symbol interference (ISI) and crosstalk between the differential pair, however, still cause significant timing jitter and amplitude noise and heavily limit the performance of the differential link. the pre-emphasis filter is commonly used to reduce ISI but may potentially change the crosstalk behavior. in this paper, we first propose formula-Based jitter and noise models considering the combined effect of ISI, crosstalk, and pre-emphasis filter. with the same set of input patterns, experiment shows our models achieve within 5% difference compared with SPICE simulation. by utilizing these formula-Based models, we then develop algorithms to directly find out the input patterns for worst-case jitter and worst-case amplitude noise through pseudo-Boolean optimization (PBO) and mathematical programming. in addition, a heuristic algorithm is proposed to further reduce runtime. Experiments show our algorithms obtain more reliable worst-case jitter and noise compared with pseudorandom bit sequences simulation and, meanwhile, reduce runtime by 25\times when using a general PBO solver and by 150\times when using our proposed heuristic algorithm. © 2006 IEEE.
