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.

本文论述了状态机的verilog编码风格,以及不同编码风格的优缺点,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.

基本的编辑工具(GENERAL EDITING FACILITIES) 对象放置(Object Placement) ISIS支持多种类型的对象,每一类型对象的具体作用和功能将在下一章给出。虽然类型不同,但放置对象的基本步骤都是一样的。 放置对象的步骤如下(To place an object:) 1.根据对象的类别在工具箱选择相应模式的图标(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根据对象的具体类型选择子模式图标(sub-mode icon)。 3、如果对象类型是元件、端点、管脚、图形、符号或标记,从选择器里(selector)选择你想要的对象的名字。对于元件、端点、管脚和符号,可能首先需要从库中调出。 4、如果对象是有方向的,将会在预览窗口显示出来,你可以通过点击旋转和镜象图标来调整对象的朝向。 5、最后,指向编辑窗口并点击鼠标左键放置对象。对于不同的对象,确切的步骤可能略有不同,但你会发现和其它的图形编辑软件是类似的,而且很直观。 选中对象(Tagging an Object) 用鼠标指向对象并点击右键可以选中该对象。该操作选中对象并使其高亮显示,然后可以进行编辑。

重写了微软提供SQLHelper(共用的数据库调用接口) 1把SqlHelper的connectionString做成一个全局量,统一设置数据库连接字符串 2增加了返回特定表名的DataSet的各接口。 可在项目的config文件设置数据库连接字符串 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> 当然可以把数据库连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).
