Fast access to hierarchy shapes

 Hi Slawa

dbGet...Overlap... functions all have an argument that you can specifiy the hierarchy levels to search. Rather than flatten the instances try:

allShapes = dbGetTrueOverlaps( dbDes list(list(box_x1 box_y1) list(box_x2 box_y2))) t 0:32 t )

This finds all the instances, mosaics and shapes that intersect the bounding box in the levels from 0 to 32. The final t returns the array row and column information so you can transform the data.

Note that the hierarchical data is returned as a list for each hierarchical element. The final ID in that list is the shape. The points of that shape are in local coordinates for its cellView that you have to transform to get the points in your current cellView. To do this, use dbTransformPoint in a loop. In IC615 you can use the new command dbGetHierPathTransform to get the final transform, otherwise you have to build up the transform with dbConcatTransform at each level of the hierarchy.

Hi Ted,

Is there a way to get only id of instances and mosiacs (no layers) hierarchial which can be processed further?

P:S :  similar to summary but hierarchial data (0:32)

Thanks

used function

dbProduceOverLapInst(). but it doesnt gives hierarchial data .. only current level

:(
