如何快速修改 PADS Logic 電路圖裡元件的編號與屬性


由於工作需要,進而找到網路上這邊文章: How to Annotate Parts in PADS Logic (schematic)..?

想要在PADS Logic裡面,修改元件的編號(reference designator),Logic似乎不是個好用的電路軟體,猜想當初開發時,可能是從layout佈局的角度,來回頭設計電路編輯軟體。

文章裡有兩種方法,第一種方法是直接下載熱心人士DenisL所提供的script (Pads Logic Parts Renaming Scripts.zip (3.9 K)),可直接在Logic裡面執行,簡單好用,不過功能沒有OrCAD強大(直接可以跳出互動性的表格工作環境)。第二種是讓Logic與Layout連結,在Layout裡面有工具可以AutoRename,然後再從Logic裡面使用"ECO from PCB",將重新編號的變更結果,回饋到電路圖上。

george_defond:
The other method is to import your schematic into Layout and use the Auto Runumber in the ECO Toolbar. PADS will fill in all your Ref Des. From there open the link to Layout in Logic and ECO from PCB will change your REf Des in Logic. Convoluted, but it works. IMO (never humble) the Script works better.

理論上,第二種方法是可行的,但是實際上,很多政策不嚴謹的公司,根本不會將電路圖與layout做緊密的結合,而往往電路圖跟layout是不同的團隊在維護,PADS用ECO做連結,在往返間,一定會跑出一大堆的錯誤,大部分是元件package/footprint對不起來,而一般使用者,一看到一堆error錯誤報告,絕對馬上打退堂鼓,以致於不會再想辦法維持兩者的正確連結。一般來說,沒有工程師有那樣的膽子,去承擔看似非常大的風險。

ps. 各位看倌,記得在電腦實驗上述方法前,先把原始檔案備份起來啊!

TED Talks: 透過大貓認識生命

Beverly 和 Dereck Joubert夫婦:透過大貓認識生命

當一頭雄獅被殺死時,整個獅群都被摧毀了。
一頭新來的雄獅會進入到該片領域,接管整個獅群,
然後,當然,首先就會殺死所有的幼獅,可能還會殺死一些保護自己幼崽的母獅。
因此我們大概估算,大概要殺死20到30頭獅子,
才能讓一頭雄獅的頭,掛到某個遙遠地方的牆上。
And you have to know that,
  when a male lion is killed, it completely disrupts the whole pride.
A new male comes into the area and takes over the pride
  and, of course, first of all kills all the cubs
  and possibly some of the females that are defending their cubs.
So we've estimated that between 20 to 30 lions are killed
  when one lion is hanging on a wall somewhere in a far-off place.

KB2833941 安全更新安裝失敗

始終搞不懂為何微軟就是有本事把好好的東西搞到爛,.NET framework 的更新失敗真是惡名昭彰,如果不幸要重灌系統,有一半的機率會碰到這無法安裝的問題,也因此前陣子才會寫了篇幹譙文(儘管後來證實是防毒軟體的問題)。沒想到,最近出現的 MS13-052 KB2833941 安全性更新,又是不停的安裝失敗,讓我想大罵髒話。
I never understand why Microsoft always exerts the gift in destroying beautiful things. .NET framework has been notorious for the update failure. You will get 50% percent chance to face this problem if inevitably having to reinstall the whole OS. Recent MS13-052 KB2833941 security patch makes me want to spit out my curses again.

網路上最常見到的垃圾答案,就是整個 .NET framework 重裝,幫幫忙,整個 1.1, 2.0, 3.5 重裝要花多少時間,他們可是超肥大的啊 !?!? 還好,最後在某網頁裡找到 cbendan 提供的解決方法,簡而言之,就是自行下載 KB2833941  更新檔,再額外下載整個 1.1 轉散發套件並解壓縮,隨後,手動更新時會跳出視窗詢問 .NET 1.1 的檔案位置,把目錄指向剛才解壓的目錄後,便可以安裝完成。
The most common rubbish solution is to reinstall the whole .NET framework. OMG. The whole version of 1.1, 2.0, and 3.5 is obese and the process is a waste of life!!! Fortunately there's a good answer provided from cbendan. In short, the approach is to download KB2833941 patch file as well as the .NET Framework 1.1 redistributable package. Decompress the redistributable package and start to execute the patch update manually. You will be prompt for the 1.1 framework location and just provide the folder path of the decompression. Voilà. The update becomes successful.
