Cadence Allegro PCB Editor 的拿来主义，这回我们谈谈关于Allegro封装库的复用，对，就是别人已经画好的板子，量产过的，并且封装无误的板子，我们可以将封装导出来，方便自己以后使用，不用再重新画了。 Allegro PCB Editor导出封装的操作步骤如下：         然后板子上所有器件的相关封装信息便会保存在您设置的“Export to directory”目录路径下。自己去挑中意的来用吧，O(∩_∩)O~     原创文章，转载请注明：  转载自  吴川斌的博客  http://www.mr-wu.cn/  本文链接地址:  Cadence Allegro PCB Editor 如何导出封装库 复用现有PCB板上的封装库 将偷懒进行到底http://www.mr-wu.cn/cadence-allegro-pcb-editor-export-libraries/

There is a new, free website that offers an online schematic entry tool. Check it out here . There's not much new about that, except that designs on this new site are made freely available to the public. "Sharing" is the meme today, often to excess, and schematics.com offers that to those interested in electronics. As of this writing there are about 50 schematics that have been contributed. The schematic editor is initially seeded with about 5000 components from NXP, though the press release suggests other partners will eventually be included. Is the site is ready for prime-time? I loaded one of the site's sample circuits into the editor and the very first thing I tried was to move R3:   The result:   Or, moving L1:   Gave:   Moving components gives pretty unpredictable results. Otherwise, the schematic editor worked well and was fast and intuitive though short on features. Though biased towards NXP components, for now, it does have a huge parts library. I'm sure the component-moving weirdness will be fixed. The tool produces a nice BOM. If you annotate it with Digi-Key part numbers the tool can order the parts for you. Pretty sweet. I don't care for the logic symbols, which are all just boxes. Need some NAND gates? The symbol for a 74HC00 (quadruple two input NAND gates), here in a circuit, looks like:   That's pretty hard to follow. The sharing is nice. However, I can't imagine using schematics.com for anything other than playing, or for publishing small circuits. Most of us work on proprietary designs and simply cannot share our work. Sometimes IP is controlled in the commercial industry with more zeal than the intelligence community uses in their secure compartmented information facilities. Even without IP issues, would you put your new pacemaker schematic in a public forum? Some eager lawyer may start looking for subtle flaws. One must realise that the circuits contributed by the community may be brilliant bits of engineering... or not. The 450MHz mobile phone jammer is an example. It's completely illegal here in the USA, though the part number of the transistor selected makes one think the circuit was designed overseas. No doubt it works, on a good day, with carefully-selected parts at room temperature. But it sure looks unstable in frequency to me. A breathalyzer sounded like fun, but the negative input to an LM324 is unconnected:   There's no way that circuit could function. With no vetting don't trust any of the designs without doing some analysis of your own. What do you think? Would you use an online schematic editor? Or share your designs?

spb16.3下面，自己编辑一个stroke文件，结果没有生效。好像是软件运行起来没有找到那个 stroke文件的路径还是什么原因，后来编辑了G:\Cadence\SPB_16.3\share\pcb\text\allegro.strokes 文件（G是我的安装路径），就可以生效了！ 另外，最近用到了allegro16.5，修改了stroke文件之后却一直执行不了，每次右键都会出错，一直搞不懂是什么原因，stroke文件保存的位置也是对的！终于有一天，安装了java程序之后，又重新编辑stroke文件的时，出现了java程序运行的图标，之后再去pcb editor里面点击右键的时候就能用stroke定义的功能了！
