Nios II軟件構建工具入門 The Nios® II Software Build Tools (SBT) allows you to construct a wide variety of complex embedded software systems using a command-line interface. From this interface, you can execute Software Built Tools command utilities, and use scripts other tools) to combine the command utilities in many useful ways. This chapter introduces you to project creation with the SBT at the command line This chapter includes the following sections: ■ “Advantages of Command-Line Software Development” ■ “Outline of the Nios II SBT Command-Line Interface” ■ “Getting Started in the SBT Command Line” ■ “Software Build Tools Scripting Basics” on page 3–8

This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

工作環境設置及軟件安裝這章介紹工作環境的設置及軟件安裝方面知識。為什么要進行工作環境設置呢?因為現在的PCB 工程師要設計的文件很多。文件多了如果不進行管理就會很混亂,導致以后的維護十分困難。所以要從剛開始學習的時候養成一個好的操作習慣,這是很有必要的。2.1 建立自己的工作目錄在電腦的桌面上打開我的電腦,在我的電腦中打開D盤。在D 盤中建立三個文件夾。分別為“D:\EDA”“D:\EDA_LIB”“D:\EDA_PROJECT 三個文件夾”。如下圖所示:圖2-1-1 “建立工作目錄”建立好三個文件夾后,在這三個文件夾中分別另建立一個新文夾,并命名為Protel99se。三個文件夾的作用分別是:EDA文件夾是用來存放安裝文件;EDA—LIB 文件夾是用來存放元件庫。EDA—PROJECT 文件夾是用來存放設計數據。2.2 對Protel 99se 進行安裝設置好工作目錄后,就可以對軟件進行安裝。圖2-1-2就是Protel 99se的安裝程序。其中“Protel99SP6”是升級補丁,“Protel99 漢化”是漢化文件。(1)雙擊Setup 安裝圖標對軟件進行安裝。

Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.
