how to extract pad coordinates and names

Aug 16, 2006

Hi,

I am try to extract the pad coordinates associate with their names such
as:

Pad names: Coordinates

x,y)
----------------- -----------------
VDD (100:200)

Since the pad label "VDD" is a TEXT layer and placed on the top of the
pad opening.
but not attached to it, when quering, we can not see any connectivity
information from
VDD to pad. Therefore, I only able to
extract the pad coordinates in the layout but unable to get pad label
"VDD"

The goal here is to get pad coordinates with the associate pad names.

Thanks,

Tin

Try this piece of code.

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
cvId = geGetEditCellView()

listpads = leSearchHierarchy(
cvId
cvId~>bBox
0
"rectangle"
list( list( "layer" "==" list( "PAD" "drawing" ) ) )
)

foreach( pad listpads

labelPad = car(dbGetOverlaps( cvId pad~>bBox list( "text" ) 0 ))

xll=xCoord(lowerLeft(pad~>bBox))
yll=yCoord(lowerLeft(pad~>bBox))

printf("%s \t" labelPad~>theLabel )
printf("%f \t" xll )
printf("%f \n" yll )

) ; end foreach
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Hope it helps.

Thanks Kholdoun!

I will try it.

Salut Kholdoun,

BTW, my layout is hierarchical does the coordinates given by your skill
routine output absolute coordinate or relative coordinates ?

Merci,

OkGuy

Kholdoun TORKI · Aug 18, 2006

You are right. If we specify a deeper hierarchy for
the "leSearchHierarchy" fonction, the coordinates will be
the ones at that hierarchy.

A workaround would be to run a Diva script promoting the
"PAD" rectangles to the top, and then run the Skill code
I sent previously.

Example :

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(drcExtractRules
ivIf((switch "drc?") then

saveDerived(geomOr("PAD") ("PAD" "drawing"))
)
)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

I'm sure there is a cleaner way to do this.
If someone could suggest an alternative ?

The attached skill file will take information from a form and search
layout to a pre-defined depth. The form produced will list labels to
co-ordinates found.

The hierarchy default value is 20.

Hi Kevin,

This code indeed works for instances but not for mosaic .
Sometimes we create i/o (f.e. PASS1V) instance use mosaic (row = 2 or
column = 2)

In this case , if has mosaic in cell ,
pad_box = geTransformUserBBox(pshape~>bBox list(nth(0 pad_trans) will
has error ,
How can this code to handle mosaic ?

Thank you very much.
Charley

Thanks your script

I have been a great help to

However, one problem.

I want to sort PAD coordinates

(From top left, counterclockwise)

How do I fix the script?

Thank you.
