Abstract

This paper presents an adaptive timing method for analysis of deskew signaling in high-performance integrated systems. The proposed approach models the practical deskew schemes as an adaptive system to study the performance limit of deskew signaling. We investigate the statistical properties of optimal deskew, which can be considered as the theoretical limit of deskew signaling. This approach also allows us to study the related energy efficiency issues in deskew schemes. We determine the bound on energy efficiency subject to the performance constraint on deskew signaling. Simulation results show that the performance of practical deskew schemes in a 90-nm process is 23.2% away from the optimal deskew scheme, and the gap of energy efficiency is 51% above the bound.
