How can I use a tcl script to update the modified information from library to Design Cache which is in .DSN project?

Question

Hi Community, 
 If I have modified the part name and footprint in the library, for example, the part name has been changed from MAX3232EIDR to MAX3232EIPWRG4, and the footprint has been changed from SOIC16 to TSSOP16, how can I use a tcl script to update them from library to Design Cache which is in .DSN project? (with Cadence Capture CIS) 
 # 
 # 
 The following tcl script is Get Part Value from schematic and Get SourcePackage Name from Design Cache. 
 # 
 # 
 #Get Part Value from schematic 
 set lPartValueNameStr [DboTclHelper_sMakeCString] $pPlacedInst GetPartValue $lPartValueNameStr set lPartValueName [DboTclHelper_sGetConstCharPtr $lPartValueNameStr] puts "lPartValueName : $lPartValueName" 
 # 
 # 
 #Get SourcePackage Name from Design Cache 
 set lCachedPartValueNameStr [DboTclHelper_sMakeCString] $pPlacedInst GetSourcePackageName $lCachedPartValueNameStr set lCachedPartValueName [DboTclHelper_sGetConstCharPtr $lCachedPartValueNameStr] puts "lCachedPartValueName : $lCachedPartValueName" 
 #

HI Morgan, 
 
 Procedure (prco) share in the above is used to get all the properties of cached part. You can take on which common property you need to check in the library which you used to replace cache par. 
 
 Please check the page no-23 OrCAD_Capture_TclTk_Extensions_Revision1.2, you will get the library hierarchy as well as design hierarchy. 
 
 For more information on library and design hierarchy, please refer to page 23 of the OrCAD Capture Tcl/Tk Extensions Revision 1.2 document. This document provides details on how to access different classes and use their APIs to retrieve specific information. 
 
 For example: 
 
 set lCacheObjectsIter [$pDesign NewCachesIter $lStatus $::IterDefs_ALL] --> It returns DboLibCachesIter , Now in pdf I will search for class DboLibCachesIter . 
 I captured few api under that class from the pdf. 
 
 START class DboLibCachesIter(TBaseDboLibChangedObjectsIter): 
 NextCachedObject(status) : returns DboBaseObject 
 Class : DboLibCachesIter(TBaseDboLibChangedObjectsIter):

Now I will use api NextCachedObjectto get the cached object like below: 
 
 set lCachedObject [$lCacheObjectsIter NextCachedObject $lStatus] --> returns DboBaseObject, now i'll find api under DboBaseObject and use those. 
 
 By following this process, you can navigate through the class hierarchy and use the available APIs to retrieve the desired information.

Please check the below article how cached parts are replaced from a library.

 Hope this is helpful for you.

 Below proc will help to get the cached lib property. 
 You can filter out the part from updated library based on attribute match from the part present in cached lib and then use below API to replace cache: 
 
 ReplaceCache(OldPackageOrSymbolName, OldLibName, NewName, NewLibName, Class : DboLib(DboBaseObject): bUpdateCache = 0, bPreserverefDes = 0) : returns DboState Class : DboLib(DboBaseObject): Parameters: OldPackageOrSymbolName: CString OldLibName: CString NewName: CString NewLibName: CString bUpdateCache: int bPreserverefDes: int

proc showCacheEntries { pDesign } { set lPrpName [DboTclHelper_sMakeCString] set lPrpValue [DboTclHelper_sMakeCString] set lPrpType [DboTclHelper_sMakeDboValueType] set lEditable [DboTclHelper_sMakeInt] set cptr DboTclHelper_sGetConstCharPtr set lCacheNameCStr [DboTclHelper_sMakeCString] set lCacheLibNameCStr [DboTclHelper_sMakeCString] set lCachePropNameCStr [DboTclHelper_sMakeCString "Source Package"] set lCacheValNameCStr [DboTclHelper_sMakeCString] set lStatus [DboState] set lCacheObjectsIter [$pDesign NewCachesIter $lStatus $::IterDefs_ALL] set lCachedObject [$lCacheObjectsIter NextCachedObject $lStatus] while { $lCachedObject!= "NULL" } { set lCachedLibObject [DboBaseObjectToDboLibObject $lCachedObject] set lPropsIter [$lCachedLibObject NewEffectivePropsIter $lStatus] set lStatus [$lPropsIter NextEffectiveProp $lPrpName $lPrpValue $lPrpType $lEditable] while {[$lStatus OK] == 1} { if {[$cptr $lPrpName] != ""} { puts "	Name=[$cptr $lPrpName] Value= [$cptr $lPrpValue] " } set lStatus [$lPropsIter NextEffectiveProp $lPrpName $lPrpValue $lPrpType $lEditable] } delete_DboEffectivePropsIter $lPropsIter # $lStatus -delete # puts "Value: = [DboTclHelper_sGetConstCharPtr $lCacheValNameCStr]" # $lCachedObject GetName $lCacheNameCStr # $pDesign GetSourceLibName $lCacheNameCStr $lCachedLibObject $lCacheLibNameCStr # puts -nonewline "[DboTclHelper_sGetConstCharPtr $lCacheNameCStr] : " set lCachedObject [$lCacheObjectsIter NextCachedObject $lStatus] } delete_DboDesignCachesIter $lCacheObjectsIter $lStatus -delete } 
 
 Hope it helps. 
 Do let me know if you require any help.
