摘　　要：结合SA2669激光驱动芯片的测试系统进行仿真,仿真并分析了基于IBIS模型的高速数据采集系统的信号完整性问题。发现并解决该测试系统的存在会影响到性能的反射、振铃问题,提出了修改建议,并取得良好的仿真结果。结果证明高速电路设计中采用基于信号完整性的仿真设计是必要的、可行的。Simulation is made on the motherboard system based on the SA2669. Through a thorough simulation, many potential problems that may degrade performance or cause functional disorder are dug out. To solve the problems, some advice is given and some fixing up work has been done. It is shown that the SI simulation is not only feasible but also essential in high speed circuit design.
