leSearchHierarchy() layers origin problem

Sarvani
Sarvani over 12 years ago

 Hi all,

 1) I have used m1=leSearchHierarchy( cv cv~>bBox 32 "any shape" list(list("layer" "==" list("M1" "drawing")))) to get all M1 layers (from hirerchy also). But when I enter dbLayerSize(cv list("y2" "drawing")  m1 0.2) in CIW then Y2 layer is placed at different points from original m1 layers(getting mismatch for hirerchy m1 layers only). Please let me know how can I overcame this.

2) And  is there any command which is faster than leSearchHierarchy.

 

Thank you,

Sarvani

    Hi Lawrence,

    Thank you verymuch for reply.

    1)It is working now. How can I get exact overlap area between two layers? I have been tring to write autovia code(like option which is in IC615, my version is 5141). Now I have layers m1,m2 at point. I have to get overlap area of both layers.

    2)When My object is in hirerchy how can I get exact points of object. I'm unable to get bBox of that point as per top level.

    Code still in progress

    cv=geGetEditCellView()
    enterPoint( ?prompts
    list( "Enter a point.")
    ?doneProc "pointDone"
    )
    procedure(pointDone(w done pts)
    let((figlist1 figlist2 figlist)
    figlist1= dbGetOverlaps(cv list(car(pts) car(pts)) list("M1" "drawing") 32 t)
    figlist2= dbGetOverlaps(cv list(car(pts) car(pts)) list("M2" "drawing") 32 t)
    figlist=append(figlist1 figlist2))

    ;need to find overlap area of two layers

    )

    techFindViaSpec() ;command still pending
    leCreateContact() or dbCreateContact(); command pending
