在当今的电子设计过程中，信号完整性问题的研究和处理已经成为不容忽视的重要环节。在电路的设计初期 要利用电路设计软件仿真，充分考虑可能出现的问题，及时发现及时解决，节约成本，缩短产品开发周期。文中给出了在Altium Designer 中的仿真波形，从仿真结果可以清楚地看到采取不同的解决办法，信号完整性问题改善的效果不同，因此要根据 电路设计的实际需求采用合适的最佳解决方案。

In today's electronic design process, the research on signal integrity has become an important part that should not be ignored. At the early of the circuit design process, the circuit design simulation software should be used, considering the problems and resolving them to shorten the product development cycle. This paper presents the simulation waveforms in Altium Designer. Results show that different solutions lead to different signal performance. So we should adopt the best solution according to the actual conditions of the circuit design program.
