摘要
信号完整性问题已成为当今高速PCB设计的一大挑战,传统的设计方法无法实现较高的一次设计成功率,急需基于EDA软件进行SI仿真辅助设计的方法以解决此问题。在此主要研究了常见反射、串扰、时序等信号完整性问题的基础理论及解决方法,并基于IBIS模型,采用Cadence_Allegro软件的Specctraquest和Sigxp组件工具对设计的高速14位ADC/DAC应用系统实例进行了SI仿真与分析,验证了常见SI问题解决方法的正确性。
Signal Integrity （SI） problem has became one of the greatest challe_nge in high-speed PCB design area, the traditional design method is hard to realize high once-th＇rough design success, SI simulation aided design＇ method based on EDA software is demanded to solve this problem. The basi＇c theory and solutions of some normal SI problems such as reflection, crosstalk and timing are researched. SI analysis and simulation of a high-speed 14bits ADC/DAC application system based on Specetraquest and Sigxp in Cadence_Allegrospb 16.0 are designed, the validity of the solutions to the SI problems is verified.
