This application note is intended for system designers who require a hardware implementation overview of the development board features such as the power supply, the clock management, the reset control, the boot mode settings and the debug management. It shows how to use the High-density and Medium-density STM32F10xxx product families and describes the minimum hardware resources required to develop an STM32F10xxx application.

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。

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

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.

Methods for designing a maintenance simulation training system for certain kind of radio are introduced. Fault modeling method is used to establish the fault database. The system sets up some typical failures， follow the prompts trainers can locate the fault source and confirm the type to accomplish corresponding fault maintenance training. A training evaluation means is given to examining and evaluating the training performance. The system intuitively and vividly shows the fault maintenance process， it can not only be used in teaching， but also in daily maintenance training to efficiently improve the maintenance operation level. Graphical programming language LabVIEW is used to develop the system platform.

為了滿足現代高速通信中頻率快速轉換的需求，基于坐標旋轉數字計算（CORDIC，Coordinate Rotation Digital Computer）算法完成正交直接數字頻率合成（ODDFS，Orthogonal Direct Digital Frequency Synthesizer）電路設計方案。采用MATLAB和Xilinx System Generator開發工具搭建電路的系統模型，通過現場可編程門陣列（FPGA，Field Programmable Gate Array）完成電路的寄存器傳輸級（RTL，Register Transfer Level）驗證，仿真結果表明電路設計具有很高的有效性和可行性。
