ORCAD在使用的時候總會出現這樣或那樣的問題…但下這個問題比較奇怪…在ORCAD中無法輸出網表…彈出下面的錯誤….這種問題很是奇怪…Netlist format: tango.dllDesign Name: D:\EDA_PROJECT\PROTEL99SE\YK\SV3200\MAIN.DSNERROR [NET0021] Cannot get part.[FMT0024] Ref-des not found. Possible Logical/Physical annotation conflict.[FMT0018] Errors processing intermediate file找了一天沒找到問題…終于在花了N多時間后發現問題所在…其實這個問題就是不要使用ORCAD PSPICE 庫里面的元件來畫電路圖…實際中我是用了PSPICE里面和自己制作的二種電阻和電容混合在一起…就會出現這種問題…

PCB設計問題集錦 問:PCB圖中各種字符往往容易疊加在一起,或者相距很近,當板子布得很密時,情況更加嚴重。當我用Verify Design進行檢查時,會產生錯誤,但這種錯誤可以忽略。往往這種錯誤很多,有幾百個,將其他更重要的錯誤淹沒了,如何使Verify Design會略掉這種錯誤,或者在眾多的錯誤中快速找到重要的錯誤。 答:可以在顏色顯示中將文字去掉,不顯示后再檢查;并記錄錯誤數目。但一定要檢查是否真正屬于不需要的文字。 問: What’s mean of below warning:(6230,8330 L1) Latium Rule not checked: COMPONENT U26 component rule.答:這是有關制造方面的一個檢查,您沒有相關設定,所以可以不檢查。 問: 怎樣導出jop文件?答:應該是JOB文件吧?低版本的powerPCB與PADS使用JOB文件。現在只能輸出ASC文件,方法如下STEP:FILE/EXPORT/選擇一個asc名稱/選擇Select ALL/在format下選擇合適的版本/在Unit下選Current比較好/點擊OK/完成然后在低版本的powerPCB與PADS產品中Import保存的ASC文件,再保存為JOB文件。 問: 怎樣導入reu文件?答:在ECO與Design 工具盒中都可以進行,分別打開ECO與Design 工具盒,點擊右邊第2個圖標就可以。 問: 為什么我在pad stacks中再設一個via:1(如附件)和默認的standardvi(如附件)在布線時V選擇1,怎么布線時按add via不能添加進去這是怎么回事,因為有時要使用兩種不同的過孔。答:PowerPCB中有多個VIA時需要在Design Rule下根據信號分別設置VIA的使用條件,如電源類只能用Standard VIA等等,這樣操作時就比較方便。詳細設置方法在PowerPCB軟件通中有介紹。 問:為什么我把On-line DRC設置為prevent..移動元時就會彈出(圖2),而你們教程中也是這樣設置怎么不會呢?答:首先這不是錯誤,出現的原因是在數據中沒有BOARD OUTLINE.您可以設置一個,但是不使用它作為CAM輸出數據. 問:我用ctrl+c復制線時怎設置原點進行復制,ctrl+v粘帖時總是以最下面一點和最左邊那一點為原點 答: 復制布線時與上面的MOVE MODE設置沒有任何關系,需要在右鍵菜單中選擇,這在PowerPCB軟件通教程中有專門介紹. 問:用(圖4)進行修改線時拉起時怎總是往左邊拉起(圖5),不知有什么辦法可以輕易想拉起左就左,右就右。答: 具體條件不明,請檢查一下您的DESIGN GRID,是否太大了. 問: 好不容易拉起右邊但是用(圖6)修改線怎么改怎么下面都會有一條不能和在一起,而你教程里都會好好的(圖8)答:這可能還是與您的GRID 設置有關,不過沒有問題,您可以將不需要的那段線刪除.最重要的是需要找到布線的感覺,每個軟件都不相同,所以需要多練習。 問: 尊敬的老師:您好!這個圖已經畫好了,但我只對(如圖1)一種的完全間距進行檢查,怎么錯誤就那么多,不知怎么改進。請老師指點。這個圖在附件中請老師幫看一下,如果還有什么問題請指出來,本人在改進。謝!!!!!答:請注意您的DRC SETUP窗口下的設置是錯誤的,現在選中的SAME NET是對相同NET進行檢查,應該選擇NET TO ALL.而不是SAME NET有關各項參數的含義請仔細閱讀第5部教程. 問: U101元件已建好,但元件框的拐角處不知是否正確,請幫忙CHECK 答:元件框等可以通過修改編輯來完成。問: U102和U103元件沒建完全,在自動建元件參數中有幾個不明白:如:SOIC--》silk screen欄下spacing from pin與outdent from first pin對應U102和U103元件應寫什么數值,還有這兩個元件SILK怎么自動設置,以及SILK內有個圓圈怎么才能畫得與該元件參數一致。 答:Spacing from pin指從PIN到SILK的Y方向的距離,outdent from first pin是第一PIN與SILK端點間的距離.請根據元件資料自己計算。

Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.

pdnMesh is an automatic mesh generator and solver for Finite Element problems. It will also do post-processing to generate contour plots and Postscript printouts. GUI support using GTK or MFC (Win32) is available. The problem definition can be done in any form and given to pdnMesh as an input data file. Drawing Exchange format (DXF) files can be directly imported to pdnmesh. The quality and the coarseness of the mesh can be controlled by giving input parameters.
