How to get coordinates of layers

I am assuming you the layout is flat data or shapes, not instances or pcells

This might get you some info to start.

load the script 

Select your shapes then excute the script.

 procedure(printPts()
let(    (type
    (cnt 0)
    (objList geGetSelSet()))

foreach(obj objList
    ++cnt
    type = obj~>objType
    case(type
        ("inst"
            printf("%s %L at %L\n" type obj~>xy))
        ("rect"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>bBox))
        ("polygon"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>points))
        ("path"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>points))
        ("pathSeg"
            printf("%s on layer %L at %L\n" type obj~>lpp list(obj~>beginPt obj~>endPt)))
        ("label"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>xy))
        (t    printf("%s not defined\n" type))
    )
)
printf("%n objects selected\n" cnt)
); end of let
); end of printPts

You can find more about the objects from selecting an object/s then executing in the ciw the command geGetSelSet()~>? this will output the variables to the object or geGetSelSet()~>?? will output the variables and values.

Thanks psill!

 It works.

Hi , 

I want to get the code for finding the coordinates of a Layer which is inside a Pcell ?  

And it is not flattened .

Hi Binoy,

If you have the instance id of the instance, you can access all the shapes by doing:

instId~>master~>shapes

or on each layer purpose pair by doing:

M1=car(exists(lpp instId~>master~>lpps lpp~>layerName=="Metal1" && lpp~>purpose=="drawing"))
M1~>shapes

of course, having got the shapes, you can find out the ~>bBox of each or whatever you want. The "coordinates of a layer" is a bit vague, so it's not obvious what you want to do with them.

You might need to use dbTransformPoint or dbTransformBBox of points or bounding box with instId~>transform as the second argument if you want the coordinates referred to the cellView the pcell is instantiated in, otherwise they are relative to the origin of the pcell.

Andrew.

Hi, I used this method to extract layers from pcell. how ever would you please let me know. how do I trace the connectivity at current hierarchy of those shapes. The pcells are present at current hierarchy/cellview. using above I extracted "PO" layers and filtered to find out only those "PO" shapes where net name is defined. however these net names are names inside PCELL like "G" for gate. at current hierarchy these "PO" shapes have "GT" connectivity. so how to get this "GT" connectivity from the extracted shapes. please let me know if I need to provide any further info>
below is my code

my_po_shapes = car(exists(a inst_id~>master~>lpps a~>layerName == "PO"))

shapes_with_connectivity = setof(a my_po_shapes~>shapes a~>net~>name!=nil)

thanks And Regards,

If you look at the instTerms on the pcell instance, you can find the instTerm with a name "G" and then find the net for the instTerm. From that net, you can look at all the ~>figs on that net, and that will give you all the shapes on the net at this level connected to the G terminal of the device in question. From these shapes you can filter all of those which are on the desired layer-purpose.

Andrew.
