Regarding "dbGetTrueOverlaps()"

Neeraj Vardhan

Hi,

I am writing a code to get all instances under a marker layer. I tried to use dbGetTrueOverlaps() but it failed with an error of "*Error* dbGetTrueOverlaps: Invalid bBox - (((-0.915 0.025) (4.695 3.135)))". I have mentioned the code below, 

 

 procedure(nvGetVia3()

cv=geGetEditCellView()

x=geGetSelSet()

y=x~>bBox

shape_new=dbGetTrueOverlaps(cv y)

)

 

Thanks & Regards

Neeraj 

 

  • This operation is different in 5.1.41 as comapred with 6.1.x since vias are instances in the old version and via objects in the new version. Here are two ways you could do this:

    5.1.41
    via5s = setof(x dbProduceOverlapInst(geGetEditCellView() shape~>bBox 0) x~>cellName == "VIA5")

    6.1.5:
    via5s = setof(x dbViaQuery(geGetEditCellView() shape~>bBox 0 0) x~>cellName == "VIA5")

    In the examples above, shape refers to the object you're using for your bBox. It could be car(selectedSet()).

  • Derek,

    Your IC615 code will only work for customVias. Probably best to do x~>viaHeader~>viaDefName=="VIA5" rather than looking at x~>cellName; this will work for both customVias and stdVias.

    The IC5141 code is of course fine, since vias are just instances.

    Regards,

    Andrew.
