Today’s digital systems combine a myriad of chips with different voltage configurations.Designers must interface 2.5V processors with 3.3V memories—both RAM and ROM—as wellas 5V buses and multiple peripheral chips. Each chip has specific power supply needs. CPLDsare ideal for handling the multi-voltage interfacing, but do require forethought to ensure correctoperation.

本文論述了狀態機的verilog編碼風格,以及不同編碼風格的優缺點，Steve Golson's 1994 paper, "State Machine Design Techniques for Verilog and VHDL" [1], is agreat paper on state machine design using Verilog, VHDL and Synopsys tools. Steve's paper alsooffers in-depth background concerning the origin of specific state machine types.This paper, "State Machine Coding Styles for Synthesis," details additional insights into statemachine design including coding style approaches and a few additional tricks.

基本的編輯工具(GENERAL EDITING FACILITIES) 對象放置(Object Placement) ISIS支持多種類型的對象，每一類型對象的具體作用和功能將在下一章給出。雖然類型不同，但放置對象的基本步驟都是一樣的。 放置對象的步驟如下(To place an object:) 1.根據對象的類別在工具箱選擇相應模式的圖標(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根據對象的具體類型選擇子模式圖標(sub-mode icon)。 3、如果對象類型是元件、端點、管腳、圖形、符號或標記，從選擇器里(selector)選擇你想要的對象的名字。對于元件、端點、管腳和符號，可能首先需要從庫中調出。 4、如果對象是有方向的，將會在預覽窗口顯示出來，你可以通過點擊旋轉和鏡象圖標來調整對象的朝向。 5、最后，指向編輯窗口并點擊鼠標左鍵放置對象。對于不同的對象，確切的步驟可能略有不同，但你會發現和其它的圖形編輯軟件是類似的，而且很直觀。 選中對象(Tagging an Object) 用鼠標指向對象并點擊右鍵可以選中該對象。該操作選中對象并使其高亮顯示，然后可以進行編輯。

重寫了微軟提供SQLHelper(共用的數據庫調用接口） 1把SqlHelper的connectionString做成一個全局量，統一設置數據庫連接字符串 2增加了返回特定表名的DataSet的各接口。 可在項目的config文件設置數據庫連接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] <!-- application specific settings --> <appSettings> <add key="ConnectionString" value="packet size=4096 user id=sa data source=localhost persist security info=True initial catalog=NorthWind password= "/> </appSettings> 當然可以把數據庫連接方法修改后直接用。

Lachesis an IRCRPG combat engine written in a combination of C and C++. The combat engine is being written for a specific RPG, but most of the project should be useful to IRCRPGs in general. It includes a native interface to the IRC protocol to allow it to act as an IRC bot, for such uses as dice rolling and acting as a remote-controlled client (RPG NPC perhaps).
