使用導入精靈來導入PADSLayout檔案

從AltiumDesigner的檔案選單來啟動導入精靈。

右擊跳出選單，會每個頁面-一步步來引導您導入檔案。

導入的檔案如下：

（FilesintheImportWizardtranslateasfollows）

（1）PADSASCIIPCBLayout（*.ASC）檔案轉換到AltiumDesignerPCB檔案（*.PcbDoc）

PADSASCIIPCBLayout（*.ASC）filestranslatetoAltiumDesignerPCBfiles（*.PcbDoc）

（2）PADSASCIIPCBLibrary檔案轉換到AltiumDesigner的PCBlibrary檔案（*.PcbLib）

使用導入精靈導入OrCADCapture設計（UsingtheImportWizardforOrCADCaptureDesigns）

IfyouareusingOrCADCapture™SchematicfilesincombinationwithyourPADSLayoutPCBdesigns,

youcanstillusetheImportWizard.

FilesintheImportWizardtranslateasfollows:

OrCADCapture的（*.DSN）檔案轉換到AltiumDesigner的原理圖檔案。

每個頁面內。

DSN檔案：

將被轉換成一個單一的AltiumDesigner的原理圖檔案（*.SchDoc）。

OrCADCapture（*.DSN）filestranslatetoAltiumDesignerschematicfiles.

Eachpagewithina.DSNfilewillbeimportedasasingleAltiumDesignerschematicfile（*.SchDoc）.

DSN檔案將被導入為一個原理圖庫（*.SchLib）。

包括複雜的設計層次結構，都會保持不變。

Designcacheswithina.DSNfilewillbeimportedasaschematiclibrary（*.SchLib）.

Designhierarchyismaintained,includingcomplexhierarchy

這些檔案將自動建立並組成一個AltiumDesigner的PCB專案（*.PrjPCB）。

OrCADlibrary檔案.轉換如下：

OrCADCapture的10.X*.DSN檔案和專案檔案版本.無法識別的錯誤

OrCADCapture10.x*.DSNFilesandtheUnrecognizedProjectFileVersionError

通常保存在OrCADCapture10.x或更高的版本。

故請使用AltiumDesignerSummer09（或更新的版本）

來支援OrCADCapture10.x.*.的DSN檔案格式。

若使用AltiumDesigner較早期的版本，可能會出現一個無法識別的專案檔案版本錯誤。

如果你遇到這樣的問題，有兩種方法可以解決它：

Ifyouencounterthisproblem,therearetwowaysyoucanfixit:

（1）AltiumDesignerSummer09（或更新的版本）來支援OrCADCapture的10.x的檔案格式。

UpgradetoAltiumDesignerSummer09（orlater）,whichrecognizestheOrCADCapture10.xfileformat.

（2）DSN檔案去做降存-OrCADCapture10.x的版本。

Resavethe*.DSNfileinOrCADCapture10.xintheolderformat.

要做到這這一點，確定DSN是在專案面板裡，選擇OrCADCapture的10.X。

執行File»

SaveAs。

Todothis,startOrCADCapture10.x,andmakesuretheDSNisselectedintheprojectpanel.

RunFile»

SaveAs.

你會看到一個小對話框說：

刪除接腳名稱和編號。

（RemovePinNameandNumberMovement）

此複選框將出現如果接腳名稱和號碼（pinnameandnumbers）已經移至10.x.

YouwillseeasmallcheckboxsayingRemovePinNameandNumberMovement.
