DSR-UU is a DSR implementation that runs in Linux and in the ns-2 network simulator. DSR-UU implements most of the basic DSR features specified in the DSR draft (version 10). One big exception is flow extensions. DSR-UU does NOT use ARP, so do not be surprised if you do not see ARP traffic. DSR-UU instead uses its own neighbor table that sets up the MAC-to-IP translation during Route discovery.

DDR SDRAM控制器的VHDL源代碼,含詳細設計文檔。 The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS), and Digital Frequency Synthesis (DFS) functions. This application note describes a controller design for a 16-bit DDR SDRAM. The application note and reference design are enhanced versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz, 16-bit data changes at both clock edges. The reference design is fully synthesizable and achieves 133 MHz performance with automatic place and Route tools.

最近在調試PPC上的VPN程序,總是更新路由錯誤。找了一個PPC的網絡工具NSProfiler,挺不錯的,可惜沒有XX版本!一氣之下自己就決定寫一個路由表工具,目標就是做個圖形界面的Route.exe。完成版改用eVC4寫了,名稱也改為Route.exe。

The task in this assignment is to implement an airline routing system. Your system should be able to read in a ight network as a graph from a le, where airports are represented as vertices and ights between airports are represented as edges, take as input two airports and calculate the shortest Route (ie path) between them.

There exist two essentially different approaches to the study of dynamical systems, based on the following distinction: time-continuous nonlinear differential equations ? time-discrete maps One approach starts from time-continuous differential equations and leads to time-discrete maps, which are obtained from them by a suitable discretization of time. This path is pursued, e.g., in the book by Strogatz [Str94]. 1 The other approach starts from the study of time-discrete maps and then gradually builds up to time-continuous differential equations, see, e.g., [Ott93, All97, Dev89, Has03, Rob95]. After a short motivation in terms of nonlinear differential equations, for the rest of this course we shall follow the latter Route to dynamical systems theory. This allows a generally more simple way of introducing the important concepts, which can usually be carried over to a more complex and physically realistic context.

一、前序對于從校園到社會轉變的我,進入一家新公司,學習到的知識都是全新的,聞所未聞的,一切都是從零開始。面試進入一家新公司,從安裝學習PADS9.5到完成PCB板的布局布線最終提交給廠家生產,用了一個月的時間。時間過得很快,我亦有一些感想和心得愿意同大家共分享。PADS9.5軟件的安裝,我就不再多說了,我會在下一篇文章里說的很詳細,大家有需要的可以下載。軟件安裝完成之后就要進行PCB板的設計制作了,這里就有一個PADS設計流程的問題。常規PADS設計流程:設計啟動>建庫→原理圖設計>網表調入→布局→布線→驗證優化→設計資料輸出→加工。(1)設計啟動。在設計準備階段進行產品特性評估、元器件選型、準備元件、進行邏輯關系驗證等工作。(2)建庫。根據器件的手冊進行邏輯封裝和PCB封裝的創建。(3)原理圖設計。原理圖設計可以通過PADSLogi進行,(4)網表調入。通過生成網絡表或PADSLayou連接器進行元件和網絡表調入。(5)布局。在PADSLayouth通過模塊化、飛線引導等方法進行元件布局。(6)布線。通過PADS Layou和PADS Route組合進行交互式布線工作。(7)驗證優化。驗證PCB設計中的開路、短路、DFM和高速規則。(8)設計資料輸出。在完成PCB設計后,利用CAM輸出光繪、鋼網、裝配圖等生產文件。(9)加工。輸出光繪文件到PCB工廠進行PCB生產,輸出鋼網、器件坐標文件。裝配圖到STM工廠進行貼片焊接作業。以上為PADS常規設計流程,希望初學者都要按照這個流程來做,一定能夠完好的設計出一個PCB板。
