cst软件求解器原理
本人毕业之后为机械工程师，做了一年多的结构工程师后转向51单片机开发，干了几年后又被ARM的大潮所卷进入了ARM世界。现阶段从事linux驱动和嵌入式硬件开发，这是本人工作-学习-创业的笔记，本人感兴趣挺多，现阶段涉猎高速线路设计和EMC仿真，打算朝SI工程师发展，希望能够和广大同仁交流探讨。
[b]PEEC Solver [/b]
[b]Single-layer or two-layer boards don't have pure power/ground reference layers and are therefore only suitable for the low and medium frequency range. The best simulation method for this kind of application is the quasi-static Partial Element Equivalent Circuit (PEEC) technique. It generates SPICE equivalent circuits for selected nets by subdividing them into partial elements for resistance, inductance, capacitance, and conductance calculation. Skin effect and dielectric loss is correctly modeled in both the frequency and time domain. [/b]

单层或双层板没有单独的电源/地参考层,因此只适用于中低等频率范围。对这类应用最好的仿真是准静态局部元件等效电路技术。电感、电容、电阻和电导构成局部元件，众多局部元件组合成某网络；选择网络后PEEC 可以生成SPICE 等效电路了。在频域和时域中趋肤效应和介电损耗被正确建模。
Transmission Line Solver [b]When investigating signal integrity issues on high-speed multi-layer boards, a 2D transmission line modeling approach is recommended. This modeling technique automatically subdivides transmission lines along their length into homogeneous cross-sections and calculates the corresponding line parameters. The resulting sub-models are integrated into a hierarchical final simulation model that contains all parasitic electromagnetic effects for investigations like time delay, reflection, and crosstalk in multiple transmission line or bus structures. Skin effect and dielectric loss is correctly modeled in both the frequency and time domain. [/b]

传输线求解器
对高速多层电路板信号完整性进行研究时，2D传输线建模方法是值得被推荐的。该建模技术按长度自动细分传输线为均匀的剖面且计算出相应的线参数。子模型结果被整合到一个最终的分层仿真模型中，该模型包含了如时间延时.反射.串扰等所有电磁场效应。频域和时域中趋肤效应和介电损耗被正确建模。
[b]PI Solver [/b]
[b]For the analysis of power distribution networks (PDN) in multi-layer PCBs an outstanding 3D full-wave modeling technique has been implemented. It is based on the finite elements method in frequency domain (3D FE FD) and capable of analyzing the entire PCB design. Typical results are the input impedance at PWR/GND pins of microcontrollers or other components. With the built-in parts library, it is easy, for example, to investigate various decoupling capacitor strategies. [/b]

对多层电路板的配电网络(PDN)分析中杰出的3D全波建模技术已经得以实现。它是基于频域的有限元分析法,且有能力分析整个PCB。分析典型是微控制器或其他元器件的电源/地引脚输入阻抗。当有内置零件库时再分析是容易的；例如,研究不同去耦电容策略。
