Need help on Skill script to generate pad coords, and text

Basically I want a program to generate some information about the pads
and the text found on them.

Let's say all my pad master cellnames are called "signal" "dvdd" "dvss"
"avdd" and "avss" (maybe have the names in a file to be read in). Also
I have a label on the pads top level metal (metal6). I want to a
program to find each pad, and and find the pad's center point, and then
find the pad metal label located on top of it. I then would like a
printout to a file:
pad_label pad_type pad_center_coordinates
"DATA1" "SIGNAL" (30, 300)
......

I have some skill code already. I have to first use the interactive
search for the pads, and select them all, and then I can execute my
code to determine the pad center point. I wanted to somehow use skill
code search, and select, but wasn't quite sure how. Here is my code:

pads=geGetObjectSelectedSet()
file = outfile("~/pad_coords.txt")
foreach(pad pads
padBox = car(pad~>bBox)
padName = car(pad~>cellName)
iName = car(pad~>name)
print(padName file)
print(iName file)
x1 = caar(padBox)
y1 = cadar(padBox)
x2 = caadr(padBox)foreach(text texts
ltext=car(text~>theLabel)
print(ltext file)

y2 = cadadr(padBox)
newX = x1 + (x2-x1)/2
newY = y1 + (y2-y1)/2
print(newX:newY file)
println(" " file)
) ;end foreach
close(file)

I also use the search to locate the text, and then I can run my other
script to extract the info from that. Here is that script:

texts=geGetObjectSelectedSet()
file = outfile("padlabels.txt")
foreach(text texts
ltext=car(text~>theLabel)
print(ltext file)
xytext=car(text~>xy)
println(xytext file)
) ;end foreach
close(file)

If I had a script that could automate the search, and then match up the
the label with the pad, and print it out. This info would be then used
for the packaging guys for the bonding diagram.
Thanks for any help.
 
maybe have a look at leSearchHierarchy, which will return a list
of the objects matching a set of criteria exactly like UI search.

Thanks. I am having a little trouble using it. Here is what happens:

cellId = geGetEditCellView()
pads=list("pad_tmp_ml2")
leSearchHierarchy(
cellId list(-200:-200 4000:4000) 32 "inst" list("cellName"
"pad_tmp_ml2")
)

After issuing the command, I don't see anything come up in the CIW, I
don't see a list or an error. Maybe my syntax is wrong??

I would also like to issue search for mutiple cellnames as well.
 
this shoud work i hope:

leSearchHierarchy(
cellId
list(-200:-200 4000:4000)
32
"inst"
list(
list("cellName" "==" "pad_tmp_ml2")
list("cellName" "==" "other_cell_name")
...
)
)

The following syntax doesn't seem to work either:

leSearchHierarchy(cellId list(0:0 4300:4300) 32 "inst" list("cellName"
"==" "pad_tmp_ml2"))

and I get the error:

*Error* icInstMoveTrigFunc: Invalid string - "cellName"
 
because it's a list of lists, ie each criterium is a list, and
all criteria are grouped into a list :

list( list("cellName" "==" "pad_tmp_ml2") )

Thanks for the response and help. You were right I had to do a list of
lists, and this leSearchHierarchy is what I needed as well.

Also I had to use "cell name" instead of "cellName".
 
Here is the my script with some of the improvements, but still need a
little more help if possible:

Port = poport ;;defines where to print -- screen or later to a file
padName = "pad_tmp" ;; Pad cell that contains top level PAD metal
chipXY = list(0:0 4300:4300) ;; chip xy dimensions
cv = geGetEditCellView()
pads = leSearchHierarchy(cv chipXY 32 "inst" list(list("cell name" "=="
padName)))
foreach(padi pads ;;foreach pad you find do some processing
x1 = caar(padi~>bBox)
y1 = cadar(padi~>bBox)
x2 = caadr(padi~>bBox)
y2 = cadadr(padi~>bBox)
;;;;tbox = list(x1:y1 x2:y2)
padMetal = list("METAL6" "drawing")

labels = leSearchHierarchy(cv list(36:3000 40:3100) 32 "label"
list(list("layer" "==" padMetal)))
;;;;;;labels = leSearchHierarchy(cv tbox 32 "label" list(list("layer"
"==" padMetal)))

printf("LabelDbs are: %L \n" labels outPort)
);end foreach

I want to substitute a value in the 'leSearchHierarchy' function.
Instead of using the 'list(36:3000 40:3100)' I wanted to use the pads
bBox so that I can find the Metal6 label on the pad. I tried to create
a variable called 'tbox' but I think it is creating a two item list
instead of the formatting that it seems like it needs. Thanks in
advance for any help.
 
the notation x:y is equivalent to list(x y)
is this what you're not understanding?

why don't you simply use padi~>bBox??
