Hierarchically Layer generation

gparasiliti

Hi,

I need to generate a layer starting from other layers placed hierarchicaly in my layout, I used "layer generation" from layout menu but it works only in the cellview, I tried using skill commands but I don't know how I can get all layers from the instances placed in my cellview, off course my layout has many pcell placed.

Grazie,

Giuseppe

  • 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.
