dbLayerAnd() function is not working

Phuong Truong

Dear all,

I need your help on.

Below is my code:

procedure( checkNoShapeOutsideTheBoundary()

cv = dbOpenCellViewByType("testnew" "abc" "layout" "maskLayout" "r")

prBoundary = '( ((0.0 0.0) (0.03 0.01725)) )

shape_location = '( ((0.016 0.012) (0.0175 0.0125)) )


results = dbLayerAnd(cv  "M1"  shape_location  prBoundary)
println(results)

);procedure

***prBoundary: PrBoundary layer

***shape_location: M1 layer


But return the results: nil

Is there something wrong with my code? Please help to clarify.
Thank you.

Best Regards,

Phuong Truong

  • Hi Phuong,

    It fails because dbLayerAnd does not work with lists of bBox descriptions. It works with lists of database objects for the shapes you want to do the And operation and generations the new shapes in the cellView. Instead you should use dbPointArrayAnd, but this expects lists of lists of points (each list of points is the points in a polygon, so not just two points for a rectangle). You could do something like this:

    procedure(CCFbBoxToPolygon(bBox)
      destructuringBind(((llx lly) (urx ury)) bBox
        list(llx:lly llx:ury urx:ury urx:lly)
      )
    )

    result=dbPointArrayAnd(cv mapcar('CCFbBoxToPolygon shape_location) mapcar('CCFbBoxToPolygon prBoundary))

    By the way, if you were expecting your code to create a shape on M1, you probably should have opened the cellView in "a" mode (it would create the shapes, but it won't be saveable if you open in readonly mode)

    Regards,

    Andrew.
