 Hello! Everybody, GoodEvening to all,

Please, can anybody help me in giving the solution for this question. 

I am using cadence IC514 version.

I would like to select a layer using one bind key also it should deselect the same layer if I press the same bind key.

  •  A faster way to find the shapes on an lpp is to use the lpp itself which has the attribute shapes:

    layerName = car(leGetEntryLayer())
    layerPurpose = cadr(leGetEntryLayer())
    lppId = car(setof( lpp geGetEditCellView()~>lpps lpp~>layerName == layerName && lpp~>purpose == layerPurpose))
    lppId~>shapes ; This is the list of shapes in the current cellView on that layer purpose pair.

     This gives you much better performance as you are only searching a few objects (lpps) instead of many objects (shapes).

    Do the same thing with instHeaders instead of instances when searching for placements of a particular cell master. Remember that in the case of pcells, you may have multiple instHeaders, one for each variant.
