ALTIUM TO PADS STANDARD PLUS TRANSLATION

ThisdocumentdescribestheprocessoftranslatinganAltiumDesignerdesign(*.SchDocand*.PcbDocfiles)toPADSVX.2(PADSDXDesigner/PADSLayoutIntegratedflow)

Thetranslationprocesscanbesummarizedasfollows:

• EnsurethattheAltiumschematicandlayoutaresynchronizedbydoingafull“round-trip”forward-andback-annotation

• ConvertAltiumlayouttoPADSlayoutandgeneratePCBlibrary

• ImportAltiumschematicintoPADSDXDesignernetlistschematic

• SynchronizePADSDXDesignernetlistschematicandPADSLayout

• CreateaCentralLibraryfromPADSDXDesignernetlistschematic,symbollibraries,andPADS decal libraries

• ImportPADSDXDesignernetlistdesignintoanewPADSDXDesignerintegratedflowdesign

• SynchronizePADSDXDesignerintegratedflowschematicandPADSlayout.

The processmay include additionalmanual steps to fix schematic, layout, or library datacausedbyflowdifferencesbetweenAltiumDesignerandPADSStandardPlus.

• ThefollowingfilesareneededforanAltiumDesigntranslation:*.PcbDoc,*.SchDoc,*.PrjPcb,*.IntLib

• PADSStandardPlusVX.2flowmustbeinstalled.

• IfPADSVX.2 is nottheactiveflow,useStart ► All Programs ► Mentor Graphics PCB ► MGC PCB Release Switcher,toconfigurePADSVX.2 astheactiveflow.



Overview and Background

• WhatdatadoyouendupwithinthePADSIntegratedflow:

• Pads.PCBfile

• PADSDXDesignerschematicprojectdirectory

• Acentrallibraryisanindexedlibrarystructurethatincludessymbols,cells/decals/footprints,padstacksthatmakeupthedecals,andPADSlayoutdrawings.

• Objectsaregroupedinsimilarpartitions.Forexample,alldiscretesymbolsareinthediscretepartition.

• TheCentrallibraryalsodefinesallowablepropertiesforuseinschematicandlayout.

• Partinformationisstoredinthecentrallibraryincludingthesymbol,footprint,andpinmapping.PartsuseauniqueidentifierPartNumber.

• Symbolpropertydifferencesbetweenproducts.

Configure initial mapping in altium.cnv during Altium to PADS Netlist Schematic Translation (The default configuration will be fine, unless the Altium design uses custom properties.)
