出錯了：#5 Error   [ALG0050] Duplicate Pin Name "GND" found on Package Gemini_R0BA , U6A Pin Number W2: Gemini DMB V0D, 04. Gemini_DRAM-RTC-PWR-OSC (12.80, 0.80). Please renumber one of these.這種問題是什麼原因？請高手賜教.

9 m( Y  |3 P& ?, `+ R9 `好像是同一个封装里有重复的PIN NAME。

是这样的，如果建元件库的时候电源和GND管脚都用Powr Pin就不会发生这种情况了；
6 H2 Z9 }- e- ]0 {4 D6 x# _, ]如果不习惯用Power PIN，命名的时候就得注意了，得用GND1,GND2,GND3......

改了一樣。

改成power PIN还不能导网表？

Error [ALG0050] Duplicate Pin Name <Pin Name> found on < Part Reference>: <Schematic> , <Page> <LocationX> , <LocationY)>A component contains the more than one pin number with the same name and they are assigned to different nets. You can fix this problem by selecting the part and choosing Edit Part from the pop-up menu. Choose Package from the View menu, then Properties from the Edit menu. Change the value in the Name Normal column to the desired pin name.
6 r3 B  [4 A  h- xThis error occurs if you have multiple ground or power pins with the same name but different pin numbers, and you make the power pins visible and attach them to two different nets. The PST*.DAT file format does not currently support this condition. So, you need to make the power pins invisible or give each one a different name, such as GND1 and GND2 instead of just GND.
You can run the library correction utility on library files, for correcting duplicate pin names, and then use these libraries in creating new designs. After correcting the libraries you will not encounter the ALG0050 error.

给个图看一下
4 k, Q) O; D" v& ?, P$ }3 x同名的Power pin连接到相同的net是不会出错的。

我想你看看是不是你的封装PIN命名跟原理图的命名不一样，对不上呢？还是你的封装PAD有重复命名。试看看！

会不会是库里的管脚定义有问题~

  u4 O6 K) Z: a" m8 i当然是元件库里的管脚定义了
% y8 M: B! H( Y0 q) o' S+ q/ ^原理图页面上可不能定义管脚类型的
