Signal integrity for high speed DDR memory design at the Printed Circuit Board (PCB) level is very essential and important for making a robust design. This paper describes how simulation tools can be helpful for choosing best termination method and other signal integration parameter along with the design process. A Simulation tool Hyperlynx has been used for high speed digital design for DDR2 in this paper. The author's present DDR 2 design example in which the main approach is to get wide opened eye with minimum level of overshoot and undershoot.
