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

使用Nios II軟件構建工具
This chapter describes the Nios® II Software Build Tools (SBT), a set of utilities and
scripts that creates and builds embedded C/C++ application projects, user library
projects, and board support packages (BSPs). The Nios II SBT supports a repeatable,
scriptable, and archivable process for creating your software product.
You can invoke the Nios II SBT through either of the following user interfaces:
■ The Eclipse™ GUI
■ The Nios II Command Shell
The purpose of this chapter is to make you familiar with the internal functionality of
the Nios II SBT, independent of the user interface employed.

protel 99se 使用技巧以及常見問題解決方法：里面有一些protel 99se 特別技巧，還有我們經常遇到的一些問題！如何使一條走線至兩個不同位置零件的距離相同?
您可先在Design/Rule/High Speed/Matched Net Lengths的規則中來新增規則設定,最后再用Tools/EqualizeNet Lengths 來等長化即可。
Q02、在SCHLIB中造一零件其PIN的屬性，如何決定是Passive, Input, I/O, Hi-
Z,Power,…..？在HELP中能找到說明嗎？市面有關 SIM？PLD？的書嗎？或貴公司有講義？
你可在零件庫自制零件時點選零件Pin腳,并在Electrical Type里,可以自行設定PIN的
屬性,您可參考臺科大的Protel sch 99se 里面有介紹關于SIM的內容。
Q03、請問各位業界前輩,如何能順利讀取pcad8.6版的線路圖,煩請告知
Protel 99SE只能讀取P-CAD 2000的ASCII檔案格式,所以你必須先將P-CAD8.6版的格式轉為P-CAD 2000的檔案格式,才能讓Protel讀取。
Q04、請問我該如何標示線徑大小的那個平方呢
你可以將格點大小設小,還有將字形大小縮小,再放置數字的平方位置即可。
Q05、請問我一次如何更改所有組件的字型
您可以點選其中一個組件字型,再用Global的方法就可以達成你的要求。

本文論述了狀態機的verilog編碼風格,以及不同編碼風格的優缺點，Steve Golson's 1994 paper, "State Machine Design Techniques for Verilog and VHDL" [1], is agreat paper on state machine design using Verilog, VHDL and Synopsys Tools. Steve's paper alsooffers in-depth background concerning the origin of specific state machine types.This paper, "State Machine Coding Styles for Synthesis," details additional insights into statemachine design including coding style approaches and a few additional tricks.

Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis Tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.

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.
