Find a overlap of two layers if that layer present in PCell also

Mahesh gunde 1

Hi all,


I am writing code for two layers overlap.

but got stuck to write full code.

Requirement:

Using layers: "od", "nt_n"

if "od" layer present in pcell and if its overlapping this nt_n which is in shape.


my code:

MARKER_LPP = list("marker" "error")
procedure( ntn_check()
odList   =  setof(i geGetEditCellView()->shapes car(i->lpp)=="od")
ntnList  =  setof(i geGetEditCellView()->shapes car(i->lpp)=="nt_n")
nt_n_var = dbLayerAnd(geGetEditCellView() MARKER_LPP odList ntnList  )
)

This code is checking for only shapes overlap, its ignoring if layers present are in instances.

I want to know if any shapes are overlapping with Pcell layers also.

Kindly help me on this.

Thanks,

Mahesh

  • Hi Lawrence,

    Thanks for your quick response and your comment on this.
    I am extremely sorry to say one main point in this.
    if any two layers overlaps in same instance ignore and any one layer like shape or lpp then it should violate.

    Example:
    both od and nt_n is present in Pcell.
    * od is overlapping with nt_n in cell itself it should not show.

    if od/nt_n shapes are overlapping with pcell layer, then it should show.

    as per your comment everything will show, I need to filter out as I Mentioned *
    please do the needful.

    Thanks,
    Mahesh
