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(tài)機(jī)的verilog編碼風(fēng)格,以及不同編碼風(fēng)格的優(yōu)缺點(diǎn)，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(duì)象放置(Object Placement) ISIS支持多種類型的對(duì)象，每一類型對(duì)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(duì)象的基本步驟都是一樣的。 放置對(duì)象的步驟如下(To place an object:) 1.根據(jù)對(duì)象的類別在工具箱選擇相應(yīng)模式的圖標(biāo)(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根據(jù)對(duì)象的具體類型選擇子模式圖標(biāo)(sub-mode icon)。 3、如果對(duì)象類型是元件、端點(diǎn)、管腳、圖形、符號(hào)或標(biāo)記，從選擇器里(selector)選擇你想要的對(duì)象的名字。對(duì)于元件、端點(diǎn)、管腳和符號(hào)，可能首先需要從庫(kù)中調(diào)出。 4、如果對(duì)象是有方向的，將會(huì)在預(yù)覽窗口顯示出來(lái)，你可以通過(guò)點(diǎn)擊旋轉(zhuǎn)和鏡象圖標(biāo)來(lái)調(diào)整對(duì)象的朝向。 5、最后，指向編輯窗口并點(diǎn)擊鼠標(biāo)左鍵放置對(duì)象。對(duì)于不同的對(duì)象，確切的步驟可能略有不同，但你會(huì)發(fā)現(xiàn)和其它的圖形編輯軟件是類似的，而且很直觀。 選中對(duì)象(Tagging an Object) 用鼠標(biāo)指向?qū)ο蟛Ⅻc(diǎn)擊右鍵可以選中該對(duì)象。該操作選中對(duì)象并使其高亮顯示，然后可以進(jìn)行編輯。

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).
