Search a Instance in hierarchy

SkVlsi
Hello,

I want to  get a  location of certain instance in a layout cell in text file. I have writen a small skill code and it is working fine except for instance which are in level 1 and below. That  is i will get the location of inst which are on top level only. Can anyone help me to get it fix these problem. Thanks in advance.

Following is the code that i have used

procedure(lSch()
let((inst_overlaps filename)
cv=geGetEditCellView()
filename="/dir1/filename.txt"
myport = outfile(filename)
foreach(inst cv~>instances
         if(inst~>cellName == "Xcell" then
 fprintf(myport "location of cell is : %L\n" inst~>xy) )  )
  )
close(myport)))

     I would probably search the instHeaders instead of the instances. The instHeaders point to the instances. There may be more than one instHeader for each cell name, if the cells are pcells:

    instHeaders = setof( ih cvId~>instHeaders ih~>cellName == "myCell" )
    instList = foreach(mapcan ih instHeaders ih~>instances)

    Now you can start probing the other masters for the same information.You will need to do this recursively, keeping track of the transform of the instances in each master. When you get back to the top, transform the orientations and print out your answer.

    Andrew may have an example which helps do this.
