Altium 理念
Altium’s Vision"Historically, the most advanced, state of the art design tools have been prohibitively priced, with access being limited to engineers based in the few companies that could afford them. The Altium vision – unchanged since the company’s inception – is to break down these barriers to innovation and technological advancement and provide every engineer and system designer with easy access to the best possible design tools.“

演示文稿备注
Give a brief overview of Altium Limited. The main points to make on this slide are that Altium is a global company, that it has been around in the EDA industry since 1985 & that for the last 4 years has been acquiring & developing technology in the area of FPGA design.
One important area of the design process is integrating the FPGA design with the design of the final PCB. While Nexar doesn’t support board design directly, it uses the same platform & the same design capture environment as Altium’s Protel board-level design system. Because of this, we have released a new version of Protel – Altium Designer - to make the integration of the FPGA system design & the final board design easier. As Nexar & Protel share capture environments, Altium Designer will work natively with Nexar project files. This allows us to implement features such as automatic optimization of the pin out of the FPGA in Protel for board layout & routing, & automatic back annotation of pin changes back to both the board-level schematic & the FPGA project.
DXP平台下可以集成贯穿于整个PCB设计中所有的原理图设计、VHDL设计、电路仿真、信号完整性分析、嵌入式软件设计、系统验证等工具；并可以根据用户需求定制应用界面。 For example, if you open a schematic sheet, appropriate toolbars, menus and shortcut keys are activated. This feature means that you can switch from routing a PCB to producing a Bill of Materials report to running a transient circuit analysis and the correct tolls will be readily available. All toolbars, menus and shortcut keys can be configured to suit your design environment. 下面这幅图描述了一个实例,从中我们会发现,整个设计是以项目为基础的,从后缀名就可以看出,另外像原理图,PCB的设计文件都保存在相应的 子目录里,这些和Protel99SE是完全不同的,99SE中的设计是以DDB为基础的,所有的设计文件都包含在DDB里面,一旦DDB损坏,所有的设计文件 都很难恢复,而Altium Designer是以项目为基础,它只是代表了一种连接形式,所有的设计文件都可以保存在硬盘或网络的任何一个地方,当你打开工程文件时,会将相关联的文件显示在资源管理器当中,也就是说,如果我们在资源管理器中删除了某个设计文件,实际上我们并没有在硬盘上删除他,我们仅仅取消了和他的连接关系而已.

演示文稿备注
One of the greatest challenges you face as a designer is managing the large amounts of design data that is created during the design process. To provide flexible and appropriate methods of editing data, three alternate views of the data can be used to access and edit design objects: The traditional graphical view The Inspector panel (Press F11 to toggle it on and off) The List panel (Press Shift+F12 to toggle it on and off) The Filter panel (Press F12 to toggle it on and off)
.Select Design>>Template>>Set Template File Name. This option removes any existing template and uses the one you choose. . Select Design>>Template>>Update. Use this command when a template is modified and you need to refresh the sheets which use it. . Select Design>>Template>>Remove Current Template. This option removes the template but retains the old sheet size from the old template. You place special strings by selecting Place>>Text String and then pressing the TAB key. The annotation dialog displays. Clicking on the down arrow in the name field lists a special string for each of the parameters defined.Click on the string required and place it. Special strings display their content Convert Special Strings option is selected in the Graphical Editing tab of the Preferences dialog ( Tools>>Schematic Preferences ), or when the schematic is printed or plotted.

Select Tools>> preferences. This option opens a schematic setup dialog.
You can create a custom strategy, select AutoRoute -> Setup from the menus. As well as defining the set of routing passes, you can also control the via cost, and the router’s tendency to route more diagonally or more orthogonally. If you enable the orthogonal option in the SitusTM Strategy Editor you should add a recorner pass to the strategy.

Shortcut Shift+R to cycle mode; 1.Ignore Obstacle --- If you select this option, you can place tracks anywhere in the workspace. If the online DRC feature is enabled, clearance violations are flagged immediately. 2.Avoid Obstacle ---- If you select this option , you can only place tracks where they do not violate any design rules. This feature is particularly useful when using interactive routing as it allows you to route hard up against existing objects, without fear of violating any clearance rules. 3.Push Obstacle ---- If you select his option, the PCB editor will attempt to move tracks out of the way so that you can route the current track.
