  • Nios II软件构建工具入门

    Nios II软件构建工具入门 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

  • US Navy VHDL Modelling Guide

      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.

  • protel99se安装说明(如何安装)

    工作环境设置及软件安装这章介绍工作环境的设置及软件安装方面知识。为什么要进行工作环境设置呢?因为现在的PCB 工程师要设计的文件很多。文件多了如果不进行管理就会很混乱,导致以后的维护十分困难。所以要从刚开始学习的时候养成一个好的操作习惯,这是很有必要的。2.1 建立自己的工作目录在电脑的桌面上打开我的电脑,在我的电脑中打开D盘。在D 盘中建立三个文件夹。分别为“D:\EDA”“D:\EDA_LIB”“D:\EDA_PROJECT 三个文件夹”。如下图所示:图2-1-1 “建立工作目录”建立好三个文件夹后,在这三个文件夹中分别另建立一个新文夹,并命名为Protel99se。三个文件夹的作用分别是:EDA文件夹是用来存放安装文件;EDA—LIB 文件夹是用来存放元件库。EDA—PROJECT 文件夹是用来存放设计数据。2.2 对Protel 99se 进行安装设置好工作目录后,就可以对软件进行安装。图2-1-2就是Protel 99se的安装程序。其中“Protel99SP6”是升级补丁,“Protel99 汉化”是汉化文件。(1)双击Setup 安装图标对软件进行安装。

  • 开关电源EMI设计(英文版)

    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.

  • ADAM-5510KW中FPID/PID功能块之实现及应用

    ADAM-5510KW中FPID/PID功能块之实现及应用一、 ADAM-5510KW实现PID控制的方法1、ADAM-5510KW可以使用Multiprog软件提供的FPID和PID功能块来实现PID控制。2、ADAM-5510KW对可以使用的PID控制回路并无限制,实际上,取决于Scan Rate,ScanRate越低,则允许的PID回路越多。3、在实际应用中,流量、液位、压力、温度等等对象都可以进行控制。对于流量、液位、压力等等参数可以用传感器或变送器转换为电压/电流信号接入模拟量输入模块ADAM-5017进行采集;对于温度可以用热电偶模块ADAM-5018或热电阻模块ADAM-5013进行采集;输出的执行机构例如调节阀、风扇等等可由模拟量输出模块ADAM-5024进行控制。二、 ADAM-5510KW中如何调用FPID/PID功能块1、FPID功能块在ProconOS.fwl库中,先将库添加进Project中。
