Simultaneous Switching Output Noise Modeling and Simulation Methodology for 0.18 Micron

0.18μm下,同步开关输出噪声是影响信号完整性的主要噪声之一,较大的噪声有可能导致数字系统中元件的误动。本文首先简要介绍了同步开关输出噪声的产生和特点,然后给出了一种建立仿真模型和仿真的方法,这种方法快速简便而且结果精确。最后根据仿真的结果得到了一些减小同步开关输出噪声的方案。

In 0. 18 micron technology, simultaneous switching output （SSO） noise is important to the signal integrity and may induce false logic in digital application systems, the generation and the feature of SSO noise are introduced. Then a quick, easy to use and understand SSO noise modeling and simulation methodology which consistently yields reasonably accurate results are presented. Some reducing SSO noise methods based on simulation results are given.
