首先下載軟件，解壓軟件，安裝在程序中找到SEGGER,選里面的J-FLASH，進入界面，剛開始的那個界面可以忽略，不用建project也可以；單擊菜單欄的“Options---Project settings”打開設置，進行jlink配置;正在General選項，選擇“USB”，一般都是默認配置，確認一下即可;然后在CPU選項，選擇芯片型號，先選擇“Device”才能選擇芯片型號，芯片型號，要根據你使用的芯片進行選擇;在Target interface選項 里面選擇SWD模式;首先Target里面選“Connection”連接目標芯片，然后 Target--Auto進行程序燒寫;首先Target里面選擇“Connection”連接目標芯片，然后 Target--Auto進行程序燒寫.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and Compatibility with all popular development environments.

隨著科技的發展，人們在日常生活中使用的電器越來越多，電子設備的電磁兼容性（EMC）也越來越重要。所以，人們對電子設備的電磁兼容性的要求也越來越嚴格，越來越規范。而在市場競爭中，如何降低成本、減少設備體積，是各電子設備制造廠家重點研究的課題。通過對開關電源的EMI濾波電路的類別和相應的技術特點進行分析，設計出一種既能提高性能，又能降低成本的濾波電路。With the development of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic Compatibility （ EMC ） has become increasingly important. So, people electromagnetic Compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.

Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward Compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bandwidth?

EMC的分類及標準：EMC（E1ectromagnetic Compatibility）是電磁兼容，它包括EMI（電磁騷擾）和EMS（電磁抗騷擾）。EMC定義為：設備或系統在其電磁環境中能正常工作且不對該環境中的任何設備的任何事物構成不能承受的電磁騷擾的能力。EMC整的稱呼為電磁兼容。EMP是指電磁脈沖。EMC=EMI+EMS EMI：電磁干擾EMS：電磁相容性（免疫力）EMI 可分為傳導Conduction及輻射Radiation兩部分，Conduction規范一般可分為：FCC Part 15J Class B；CISPR 22（EN55022，EN61000-3-2，EN61000-3-3）Class B；國標IT類（GB9254，GB17625）和AV類（GB13837，GB17625）。FCC測試頻率在450K-30MHz，CISPR22測試頻率在150K--30MHz，Conduction可以用頻譜分析儀測試，Radiation 則必須到專門的實驗室測試。

現代電路設計不斷朝高速、高密度、低電壓、大電流趨勢發展，信號完整性（Signal Integrity，SI）、電源完整性（Power Integrity，Pl）和電磁兼容（Electromagnetic Compatibility，EMC）問題日益突出。傳統設計方法顯得力不從心，需綜合三者間相互影響進行協同設計。本文首先介紹了高速電路SI、PI及EMC問題，接著重點分析了SI-PI協同仿真分析技術以及系統EMC權衡策略。通過對SSN耦合機制的分析，討論了SI與PI之間的相互影響，并提出了兩種用于SI-PI協同仿真的簡化模型。在此基礎上開發了SI-PI協同仿真分析工具——SI-PI Co-sim Tool，并以DDR3內存仿真分析為例介紹了工具的應用。本文對SI-PI協同建模仿真技術的分析，直觀展示了電源噪聲對信號傳輸質量的影響，在此基礎上開發的SI-PI協同分析工具可很好地輔助高速電路設計。
