Not able to create rectangle over via in hierarchy

savvysaggi over 14 years ago

Hello,

I am working on one skill which creates metal rectangles on via in hierarchy.

cv=geGetEditCellView()
;println(cv)
listsofar=list()

procedure(TrHierarchyTransversal(cv listsofar)
;cv=geGetWindowCellView()
;println(cv~>instances~>master)
foreach(master cv~>instances~>master
let((nextcellview)
nextcellview=master
cond(
(!nextcellview nil)
(member(nextcellview listsofar) println("its member"))
(t
if(!listsofar
then

a=car(setof(via cv~>vias via~>viaHeader~>viaDefName=="B2YZIA"))
        ;println(a~>viaHeader~>viaDefName)
    pbox=a~>bBox

            dbCreateRect(cv "M6" pbox)


);if

listsofar=TrHierarchyTransversal(nextcellview cons(nextcellview listsofar))

cv1=(car(listsofar)~>cellView)
;println(cv)
a=car(setof(via cv1~>vias via~>viaHeader~>viaDefName=="B2YZIA"))
        ;println(a~>viaHeader~>viaDefName)
    pbox=a~>bBox

            dbCreateRect(cv1 "M6" pbox)

;);if
);t
);cond
);let
);foreach
listsofar
);procedure

ISSUE:
I this skill , it creates rectangle on via according to hierarchy level (eg. If via is present till 4th hierarchy of top then it creates rectangle over via four times)
Kindly check for the same as i am unable to catch the issue .

Kindly help me out.

Thanks & Regards

Hi Savvy,
On top of your coding, i did some modication as your request. Please refer below. At the same time i added some comment on it for each step.
procedure( TrHierarchyTransversal(cv listsofar @key save)
   let((vias cvId pbox)
      ;-------------------------------
      ; Foreach every instanceMaster
      ;-------------------------------
      foreach(master setof(x cv~>instanceMasters !member(x listsofar))
         ;---------------------------
         ; Store cell that visited
         ;---------------------------
         listsofar = cons(master listsofar)
         ;---------------------------------------
         ; Check whether the cell got via or not
         ;---------------------------------------
         when( (vias = setof(via master~>vias via~>viaHeader~>viaDefName=="B2YZIA"))
            ;---------------------------------
            ; Via found. Open cv in edit mode
            ;----------------------------------
            if( (cvId = dbOpenCellViewByType(master~>libName master~>cellName master~>viewName nil "a")) then
               foreach( via vias
                  pbox = via~>bBox
                  dbCreateRect(cvId "M6" pbox)
               );foreach
               ;---------
               ; Save it
               ;---------
               when( save
                  dbSave(cvId)
               );when
            else
               ;------------------------------------
               ; Failed to open, print warning msg
               ;------------------------------------
               warn("Failed to open cellview in edit mode.[%L %L %L]\n" master~>libName master~>cellName master~>viewName)
            );
            TrHierarchyTransversal(master listsofar ?save save)
         );foreach
      );foreach
   );let
);procedure
This is just a scratch coding, you may need to enhanced it as well.
