本文主要介紹如何在Wado設計套件中進行時序約束，原文出自 xilinx中文社區。1 Timing Constraints in Vivado-UCF to xdcVivado軟件相比于sE的一大轉變就是約束文件，5E軟件支持的是UcF（User Constraints file，而 Vivado軟件轉換到了XDc（Xilinx Design Constraints）。XDC主要基于SDc（Synopsys Design Constraints）標準，另外集成了Xinx的一些約束標準可以說這一轉變是xinx向業界標準的靠攏。Altera從 TimeQuest開始就一直使用SDc標準，這一改變，相信對于很多工程師來說是好事，兩個平臺之間的轉換會更加容易些。首先看一下業界標準SDc的原文介紹：Synopsys widely-used design constraints format, known as sDc, describes the design intent"and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. sDc has been in use and evolving for more than 20 years, making it the most popular and proven format for describing design constraints. Essentially all synthesized designs use SDc and numerous EDa companies have translators that can read and process sDc

Allegro導出 Gerber文件和鉆孔數據文件很多PCB廠家都沒有裝Allegro軟件，所以你不能直接發.brd文件。（很多PCB小廠連ProtelDXP也沒有，只支持Protel99）什么是Gerber文件Gerber文件是所有電路設計軟件都可以產生的文件，在電子組裝行業又稱為模版文件（stencil data），在PCB制造業又稱為光繪文件。可以說Gerber文件是電子組裝業中最通用最廣泛的文件格式Gerber文件是EIA的標準格式，分RS274-D和RS274-X兩種，其中RS274-X是RS274-D的擴展文件。生產制造部門在條件許可的情況下，應當盡可能要求用戶或設計部門提供RS274-X的Gerber文件，這樣有利于各工序的生產準備。準備工作為了保證出片的正確性，需要在設計PCB文件之前對一些系統參數進行設置，該設置包括畫圖的精度，圖片的尺寸，動態鋪銅的格式。設置畫圖的精度。在allegro中打開Setup->Drawing Size菜單，調出設置對話框，如圖1在對話框中確定User Units選擇Mils，Size選擇C，這樣整個作圖區域會大一點，相應的作圖范圍（Drawing Extents）變為Width：22000.00：Height：17000.00Left X和LeftY為原點坐標。Accuracy選擇2，其他根據你的尺寸自行定義。設置完成選擇OK按鈕，使配置生效。

Compact PCI（Compact Peripheral Component Interconnect）簡稱CPCI，中文又稱緊湊型PCI，是國際工業計算機制造者聯合會（PCI Industrial Computer Manufacturer's Group，簡稱PICMG）于1994提出來的一種總線接口標準。是以PCI電氣規范為標準的高性能工業用總線。為了將PCI SIG的PCI總線規范用在工業控制計算機系統，1995年11月PCI工業計算機制造者聯合會（PICMG）頒布了CPCI規范1.0版，以后相繼推出了PCI-PCI Bridge規范、Computer Telephony TDM規范和User-defined I/O pin assignment規范。

Mathematical modeling has become an important part of the research and devclopment work in engineering and scicnce. Retaining a competitive edge requiresa fast path between ideas and prototypes, and in this regard mathematical modeling and simulation provide a valuable shortcut for understanding both qualitative and quantitative aspects of scientific and engineering design. To assist you in gaining this edge, COMSOL Multiphysics offers state-of-the art performance, being built from the ground up with a Java3D interface and C/C++ solvers.The Acoustics Module is an optional package that extends the COMSOL Multiphysicsmodcling cnvironment with customized user interfaces and functionality optimizcd for the analysis of acoustics. Like all modules in the COMSOL family, it provides a brary of prewritten ready-to-run models that make it quicker and casier to analyze disciplinc-specific problcms.

一，走進UDP協議：UDP（User Datagram Protocol）協議就是“用戶數據報協議”，它是一種無連接的協議，無連接主要是和TCP協議相比較的。我們知道當利用TCP協議傳送數據的時候，首先必須先建立連接（也就是所謂的握手）才可以傳輸數據。而當計算機利用UDP協議進行數據傳輸的時候，發送方只需要知道對方的IP地址和端口號就可以發送數據，而并不需要進行連接。當然如果你非要進行連接，通過Visual C#也是可以實現的，但前提是要確定連接的遠程主機的端口號處于監聽狀態，否則程序會出現不必要的錯誤，但這是種畫蛇添足的做法，不僅丟失了UDP協議的無連接傳送數據的特點和優點，而且還給程序運行帶來了不安定的因素。所以這種方法并不值得提倡。

0引言對于一個程序員，如果要從頭開始完全由自己來編寫一個用于通信的應用程序，必須對相關的網絡協議及其它的一些底層技術有較深入的了解，編程難度比較大。Visual Basic（VB）為廣大程序員提供了基于WindowsSockets網絡編程接口的Winsock控件，它封裝了所有繁瑣的技術細節，并提供了訪問TCP和UDP網絡服務的方便途徑，只需通過設置控件的屬性并調用其方法就可輕易連接到一臺遠程計算機中，并且還可以實現雙向交換數據。因此，利用VB的Winsock 控件來編寫基于TCP和UDP協議的通信程序，可以降低編程難度，簡化應用程序。1TCP和UDP協議介紹TCP和UDP是TCP/IP協議中的兩個傳輸層協議，它們使用IP路由功能把數據包發送到目的地，從而為應用程序及應用層協議提供網絡服務。TCP（Transmission Control Protocol，傳輸控制協議）是面向連接的協議。“面向連接”就是在正式通信前必須要與對方建立起可靠的連接，這就好象平時的打電話，必須等線路接通了、對方拿起話筒才能相互通話。一個TCP連接必須要經過三次“對話“才能建立起來，其中的過程非常復雜。UDP（User Data Protocol，用戶數據報協議）是與TCP相對應的協議，是面向非連接的協議。“面向非連接”就是在正式通信前不必與對方先建立連接，不考慮對方狀態就直接發送數據，這就好象平時的發手機短信，不必考慮對方狀態，只需要輸入對方手機號就行。TCP提供的是面向連接的、可靠的數據流傳輸，而UDP提供的是面向非連接的、不可靠的數據流傳輸。面向連接的協議在任何數據傳輸前就建立好了點到點的連接，面向非連接的協議在數據傳輸之前不建立連接，而是在每個中間節點對面向非連接的包和數據包進行路由。

MotioninterfaceTM is becoming a "must-have"function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for Motionlnterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability-all at a low consumer price point.
