摘 要 瞬態(tài)仿真領(lǐng)域的許多工作需要獲得可視化數(shù)據(jù), 仿真電路不能將輸出參數(shù)繪制成圖形時研究工作將受到很大影響. 而權(quán)威電路仿真軟件PSpice 在這個方面不盡如人意. 本文提出了一種有效的解決辦法: 通過MATLAB 編程搭建一個PSpice 與MATLAB 的數(shù)據(jù)接口,使PSpice輸出數(shù)據(jù)文件可以導入到MATLAB中繪制圖形. 這令我們能夠很方便地獲得數(shù)據(jù)的規(guī)律以有效地分析仿真結(jié)果, 這項技術(shù)對于教學和工程實踐都有比較實際的幫助.關(guān)鍵詞: 瞬態(tài)仿真 仿真程序 PSpice MATLAB 可視化數(shù)據(jù)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 引言科學研究和工程應(yīng)用常需要進行電路仿真 PSpice可進行直流 交流 瞬態(tài)等基本電路特性分析 也可進行蒙托卡諾 MC 統(tǒng)計分析 最壞情況 Wcase 分析 優(yōu)化設(shè)計等復雜電路特性分析 它是國際上仿真電路的權(quán)威軟件 而MATLAB的主要特點有 高效方便的矩陣和數(shù)組運算 編程效率高 結(jié)構(gòu)化面向?qū)ο?方便的繪圖功能 用戶使用方便 工具箱功能強大 兩者各有著重點 兩種軟件結(jié)合應(yīng)用 對研究工作有很重要的意義香港理工大學Y.

The UltraScale architecture is the industr y's f irst application of leading-edge ASIC architectural enhancements in an All Programmable architecture that scales from 20 nm planar through 16 nm FinFET technologies and beyond, in addition to scaling from monolithic through 3D ICs. Through analytical co-optimization with the X ilinx V ivado® Design Suite, the UltraScale architecture provides massive routing capacity while intelligently resolving typical bottlenecks in ways never before possible. This design synergy achieves greater than 90% utilization with no performance degradation. Some of the UltraScale architecture breakthroughs include: • Strategic placement (virtually anywhere on the die) of ASIC-like system clocks, reducing clock skew by up to 50% • Latency-producing pipelining is virtually unnecessary in systems with massively parallel bus architecture, increasing system speed and capability • Potential timing-closure problems and interconnect bottlenecks are eliminated, even in systems requiring 90% or more resource utilization • 3D IC integration makes it possible to build larger devices one process generation ahead of the current industr y standard • Greatly increased system performance, including multi-gigabit serial transceivers, I/O, and memor y bandwidth is available within even smaller system power budgets • Greatly enhanced DSP and packet handling The Xilinx UltraScale architecture opens up whole new dimensions for designers of ultra-high-capacity solutions.
