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(shí)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(gè)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(gè)PSpice 與MATLAB 的數(shù)據(jù)接口,使PSpice輸出數(shù)據(jù)文件可以導(dǎo)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(xiàng)技術(shù)對(duì)于教學(xué)和工程實(shí)踐都有比較實(shí)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.

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.

Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor devices. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the device. Feature sizes are constantly shrinking, resulting in increased number of transistors being packed into the device. Today's submicron technology is also enabling large-scale functional integration and system-on-a-chip solutions. In order to keep pace with these new advancements in silicon technologies, semiconductor packages have also evolved to provide improved device functionality and performance. Feature size at the device level is driving package feature sizes down to the design rules of the early transistors. To meet these demands, electronic packages must be flexible to address high pin counts, reduced pitch and form factor requirements. At the same time,packages must be reliable and cost effective.

This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan embedded microprocessor application. This reference system also uses a DCM that isconfigured so that the phase of its output clock can be changed while the system is running anda GPIO core that controls that phase shift. The GPIO output is controlled by a softwareapplication that can be run on a PowerPC® 405 or Microblaze™ microprocessor.

FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping and lower volume applications; custom ASICswere used for high volume, cost sensitive designs. FPGAs had also been too expensive and tooslow for many applications, let alone for System Level Integration (SLI). Plus, the development

This system is the application of RCM5700 on Ethernet. Based on this system，PoE technique that makes Ethernet can also provide power were expounded with emphasis and included FAUX design the PoE resolution was realized. To achieve the requirement of this system，LM5073 and LM5576 were used to DC-DC switch. From the data of experiment，the design filled the requirement of power-need of node whose power was lower than 13W. The application of the technique can advance the degree of simulation data collections currency and standardization and avoid designing additional power system.
