Based On The Signal Integrity Analysis Of High-speed Pcb Design

With the increase of integrate circuit switch rate and PCB (Printed Circuit Board) density, Signal Integrity has become one of main problems in high-speed design . The problem caused by some factors such as parameters of devices and PCB, layout of devices on PCB and trace of high-speed signal, etc results in the unstable or even none operation of system. How to fully consider Signal Integrity and take effective measures has been pop task in PCB design trade.This paper introduces the problems of Signal Integrity in high-speed design. Discusses the correlative problems of time sequence, reflection, crosstalk and ground rebound noise. Simulates the corresponding waveform in virtue of Cadence corp. EDA software SpecctraQuest. On the base of the discussion above, I finished the actual project that is medium frequency part and DSP board design of the high-speed mobile system during the graduate period. Attain to the success of making board for the first time. On the base of Signal Integrity analysis, using corresponding method of analysis, and in virtue of powerful EDA tools, designed required PCB board. The PCB board has steady performance. Which shortens the research period, saves cost and proves that the method of Signal Integrity analysis is important to high-speed design.
