How to use Layer Boolean Functions with hierarchical objects?

archive

Hi, All.
If I want to use function

dbLayerAnd(
d_cellViewId
t_layerName
l_dbIdList1
l_dbIdList2
[ x_numVertices ]
)
 It seems that the function can not recognize hierarchical objects with list of IDs of hierarchical objects.
How can I use this function with hierarchical objects?

  • You can't - these only work with database objects in the current cellView. You'd need to flatten first, or use a verification tool (e.g. Diva, Assura) to do the layer manipulation. You could use dbFlattenInst() to bring everything to the current cellView, or copy the source shapes to dummy shapes in the top cellView and then work on those.

    I've used a flow in the past where I've used dbGetOverlaps to find hierarchical shapes, work out the transformation by concatenating all the transforms, and then use dbCopyFig to copy into the top level cellView, and then use dbLayerAnd on these shapes - and then delete the "flattened" copies.

    Regards,

    Andrew.

  • Hi Andrew,
    Could you please elaborate more on how to do layer mainpulation in Assura?

    Thanks in advance,

    Tom

  • You'd use the usual layer functions in an Assura rule deck, e.g. geomAnd, geomOr etc (see the documentation for a complete set of functions) and then use the outLayer function to output shapes to a particular layer. You can control where the output database gets written too (best to consult the documentation though).

    Regards,

    Andrew.
