Hierarchically Layer generation

Hi Quek,

With the following data I am getting some issues. For all the cases the outLayer is having some issue, and not accepting the user input.

Can you please suggest the correct way to use the function?

CCShierLayerOps(?cv geGetEditCellView() ?layer1 list("pp" "drawing") ?outLayer list("vtl_n" "drawing") ?op "GROW BY" ?size 1 ?level 1)

CCShierLayerOps(?cv geGetEditCellView() ?layer1 list("pp" "drawing") ?layer2 list("nw" "drawing") ?outLayer list("vtl_n" "drawing") ?op "AND" ?size nil ?level 1)
CCShierLayerOps(?cv geGetEditCellView() ?layer1 list("pp" "drawing") ?layer2 list("nw" "drawing") ?outLayer list("metal2" "drawing") ?op "AND" ?size nil ?level 1)
CCShierLayerOps(?cv geGetEditCellView() ?layer1 list("via1" "drawing") ?layer2 list("metal1" "drawing") ?outLayer list("metal2" "drawing") ?op "AND" ?size nil ?level 1)

Hi Subhabrata,

Are you sure that you are using the correct name for the layers?  The layer names are case sensitive, e.g. is it "Metal2" instead of "metal2" ?  You can verify the names in SKILL if you aren't too sure, something like:

tf = techGetTechFile(geGetEditCellView())
setof(lp tf~>lps lp~>purpose=="drawing")~>name
=> (... "M1" "VIA1" "M2" "VIA2" "M3" "VIA3" "M4" ...)

Hopefully this helps you?

Best regards,

Lawrence.

Hi Subhabrata

You might want to continue the discussion in this new thread which you had created and not in this old thread.

Thanks, Lawrence. That worked.

To utilize the same function I was even looking for the queries following the thread community.cadence.com/.../1348118.

Where I wanted to read the hierarchy first and place the generated layers in there individual hierarchies, in place of adding the generated layers at the top level.

I was looking for the suggestions with reference to the CCShierLayerOps procedure call. Here is the sample that I was trying to use:

procedure(CreateLayerHier(libName viewName inputLay1 inputLay2 outLayer opt size level @optional listOfCells)

let((cv libId cellId cellList)

libId = ddGetObj(libName)
if(!listOfCells then
cellList = libId~>cells
else
cellList = nil
foreach(cellName listOfCells
cellId = ddGetObj(libName cellName)
cellList = append(list(cellId) cellList)
);end foreach
);end if

foreach(cell cellList
foreach(view cell~>views
;; using views matching viewName variable.
if(view~>name == viewName && (cv = dbOpenCellViewByType(libName cell->name
view~>name "" "a")) then
printf("\nOpened view %L from cell %L of library %L for edit.\n"
cv~>viewName cv~>cellName cv~>libName)

foreach(shape cv~>shapes
if((shape~>objType!="textDisplay" && shape~>objType!="inst" && shape~>objType!="path") then
printf("\n Creating the layer %L. " outLayer )

CCShierLayerOps(?cv geGetEditCellView() "inputLay1" "inputLay2" "outLayer" "opt" "size" "level")

);end if
);end foreach

dbSave(cv)
dbClose(cv)
);end if
);end foreach view
);end foreach cell

Thank you for the support.

HI,

I am waiting for the reply of my previous mail.

As well I want to check, how I can block the generation of the layer, if the ouLayer is already placed based on the reference layer.

Please let me know.

Thanks for your support.
