摘 要 瞬态仿真领域的许多工作需要获得可视化数据, 仿真电路不能将输出参数绘制成图形时研究工作将受到很大影响. 而权威电路仿真软件PSpice 在这个方面不尽如人意. 本文提出了一种有效的解决办法: 通过MATLAB 编程搭建一个PSpice 与MATLAB 的数据接口,使PSpice输出数据文件可以导入到MATLAB中绘制图形. 这令我们能够很方便地获得数据的规律以有效地分析仿真结果, 这项技术对于教学和工程实践都有比较实际的帮助.关键词: 瞬态仿真 仿真程序 PSpice MATLAB 可视化数据The Data Transfer from Pspice to MATLABWu hao Ning yuanzhong Liang yingAbstract Many works in the area of transient simulation has shown how a emulator such asPSpice can be interfaced to an control analysis package such as MATLAB to get viewdata. Thepaper describes how such interfaces can be made using the MATLAB programming. The platformas a typical platform will solve the problem that PSpice software sometimes can not draw the datato a picture. It can make us find the rule from numerous data very expediently, so we can analyzethe outcome of the simulation. And it also can be used in the field of education.Keywords Transient Simulation Emulator PSpice MATLAB Viewdata1 引言科学研究和工程应用常需要进行电路仿真 PSpice可进行直流 交流 瞬态等基本电路特性分析 也可进行蒙托卡诺 MC 统计分析 最坏情况 Wcase 分析 优化设计等复杂电路特性分析 它是国际上仿真电路的权威软件 而MATLAB的主要特点有 高效方便的矩阵和数组运算 编程效率高 结构化面向对象 方便的绘图功能 用户使用方便 工具箱功能强大 两者各有着重点 两种软件结合应用 对研究工作有很重要的意义香港理工大学Y. S. LEE 等人首先将PSpice和MATLAB结合 开发了电力电子电路优化用的CAD 程序MATSPICE[6] 将两者相结合的关键在于 如何用MATLAB 获取PSpice的仿真数据 对此参考文献 6 里没有详细叙述 本文着重说明用MATLAB 读取PSpice仿真数据的具体方法本论文利用MATLAB对PSpice仿真出的数据处理绘制出后者无法得到或是效果不好的仿真图形 下面就两者结合使用的例子 进行具体说明

Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed however, most of the work on Pango so far has been done using the GTK+ widget toolkit as a test platform. Pango forms the core of text and font handling for GTK+-2.x.

With the rapid expansion of wireless consumer products,there has been a con- siderable increase in the need for radio-frequency (RF) planning, link plan- ning, and propagation modeling.A network designer with no RF background may find himself/herself designing a wireless network. A wide array of RF planning software packages can provide some support, but there is no substi- tute for a fundamental understanding of the propagation process and the lim- itations of the models employed. Blind use of computer-aided design (CAD) programs with no understanding of the physical fundamentals underlying the process can be a recipe for disaster. Having witnessed the results of this approach, I hope to spare others this frustration.

Never have telecommunications operations and network management been so important. Never has it been more important to move away from practices that date back to the very beginning of the telecommunications industry. Building and con- necting systems internally at low cost, on an as - needed basis, and adding software for supporting new networks and services without an overall architectural design will not be cost effective for the future. Defi ning operations and network manage- ment requirements at the 11th hour for new technologies, networks, and services deployments must also change.
