Signal Integrity Simulation of High Speed Serial RapidIO Bus Backboard

Signal integrity (SI) is a key problem in design of high speed bus. In this paper, the SI of high speed bus signal above 109Hz is analyzed, and ways to improve SI are put forward with respect to the influences of loss, crosstalk and reflection on SI. In the design of the high speed backboard, with the help of HyperLynx, a method for simulation and validation is proposed, in which LineSim is adopted to evaluate the main parameters affecting SI and achieve guiding data for design, and BoardSim is also adopted to validate the designed high speed backboard. The feasibility of the designed high speed serial rapidIO bus backboard is theoretically proved.
