Ideas/Help Needed for Padstack Edit

archive
Hi Guys I give up, I tried for a while and now I don’t know what to do This is what I want to do in Skill 1.  Load a Padstack 2.  Edit the pad-definition on only selected layers, either make them null or assign a new value I tried the following methods 

Method 1:

 a.  Get All padstacks b.  Foreach padstack and foreach pad-definition make a copy of pad definition a.  Using make_axlPadStackPadb.  Modify the values if neededc.  Create a New Padstack  Replace the old padstack with new padstack

                Problem:

a.  Not able to create the pad-definition structure, error prone 

Method 2:

a.  Foreach padstack I use axlDBCopyPadstack and trim it by specifying the start/end layerp1=axlLoadPadstack("CIR60D40")p2 = axlDBCopyPadstack(p1, '("CONDUCTOR/RDL_SEC" "CONDUCTOR/TOP_PRM"), t)axlPadstackToDisk(p2->name)

Problem:

a.  This doesn’t seem to work, the resulting padstack still has all the pad definition on the other layersb.  Trimming doesn’t seems to work 

Method 3:

a.  Use Allegro Scripting all the way

Problem:

a.  Error Prone and there is no way to control occasional out of blue pop-ups  I am out of ideas and would appreciate any kind of help on this issue  Is there is any way I can load a padstack and go to a certain padstack definition on a given layer and change its vaule

regards

Vramanan
