Systemview仿真軟件的應用:利用系統設計、分析和仿真的可視化開發環境—Systemview 軟件平臺進行通信原理課程教學, 對Systemview 仿真軟件進行了簡要的介紹.并以2DPSK的調制解調原理為例分析了仿真過程，結果表明通過用Systemview 軟件仿真,可以很方便地得到所設計電路的輸出結果與分析波形。關鍵詞：Systemview；仿真；2DPSK通信原理是電子信息工程、通信工程等專業的一門重要的專業基礎理論課，能否正確理解其概念和基本理論對后續專業課程的學習非常關鍵。由于該課程公式和理論推導較多，學起來相對乏味，單純依靠課堂講解, 很難理解，只有借助一定的輔助工具，才能讓學生更好的掌握這門課程。為了使學生能從動態上更直觀地形象地理解這些理論, 可以采用動態系統仿真軟件System view以增強課堂教學效果,從而使學生更好地掌握其基礎理論。

keil 使用筆記:在Memory窗口上輸入address_type:address才能看到正確地址的變量debug～perfermance analyzer加入要察看的模塊名稱，然后view～perfermance analyzer window 可以察看各個模塊運行時間①Display address_type:address B:Bit address C:Code Memory Bx:Code Bank D D：80H 命令可以查看特殊寄存器 data D I：0 命令可以查看內部RAM數據iData； D X：0 命令可以查看外部RAM數據xData； ②R1 //顯示R1 register ~R1 //顯示變量R1 R1 = R7 //對寄存器Rx操作R1 = --R7 R1 = 0x20 ③main //顯示main()的開始地址d main //顯示main()的代碼④向RAM.ROM中寫數據Enter data_type address_type:address expr,expr.... data_type:int char double float long E char data:0x20 1,2,3,4 //向data區0x20開始的地址寫1,2,3,4 變量放在RAM的30H，要把定義放在main前面!另外特別注意，內部RAM通常供C程序存放中間變量等，所以一定要看看編譯后的程序中是否存在存儲單元沖突的情況，比如如果程序中 使用了別的寄存器組的話，08-1FH單元就不能用了unsigned long data i _at_ 0x30

為了能夠滿足基站易于選址、優質快速的建站要求和易維護、低成本、高可靠的運行要求，本文對以方艙來實現一體化結構基站做出一番探討。從系統設計的觀點闡述了移動通信高性能基站天線設計的幾個關鍵問題，介紹了智能天線技術在基站中的應用，并且用HFSS軟件仿真了一種新型的對稱陣子天線，該天線駐波比小于2的帶寬可以達到60%，具有良好的寬頻帶特性。 Abstract: In order to meet the station construction requirement of easy site selection and fast base station， and meet the operational requirement of easy maintenance， low cost and high reliability， this paper discussed the unified architecture base station using shelter. Several key problems of high performance mobile communication base station antenna were illustrated from the view of system design， the application of smart antenna in base station was also introduced. And a novel dipole antenna was simulated by using HFSS， the VSWR of the antenna is less than 2， and the bandwidth was reach to 60%. So it has good broadband properties.

IP核生成文件：（Xilinx/Altera 同） IP核生成器生成 ip 后有兩個文件對我們比較有用，假設生成了一個 asyn_fifo 的核，則asyn_fifo.veo 給出了例化該核方式（或者在 Edit－》Language Template-》COREGEN 中找到verilog/VHDL 的例化方式）。asyn_fifo.v 是該核的行為模型，主要調用了 xilinx 行為模型庫的模塊，仿真時該文件也要加入工程。（在 ISE中點中該核，在對應的 processes 窗口中運行“ view Verilog Functional Model ”即可查看該 .v 文件）。如下圖所示。

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.
