Search,select and then make cell?

jazzmatazz
Hello guys ,

Here is my problem. I wanna  to do hierarchically search for cell with certain criterias then to select it/ 'em and to make new cell only with this cell/s ,but I know only how to achieve the first step. I use procedural function for hierarchically search

   leSearchHierarchy( cv,bbox ... etc. )

Which returned me a list of all objects that meet the object type and search criteria. That's OK but  then I don't  know how to use this answer and to make new cell with this objects?

Regards,
Jazzmatazz

    Hi Andrew,

    I was trying to get the coordinates of a hierarchical instance with respect to the top level and i wanted to place the same instance in a new layout at exactly the same coordinates.

    As discussed previously in this post, leSearchHierarchy() directly gives the database-id of the instance and it does not have data that can be used with the bbox-transform functions to push the coordinates to the top level. The direct commands used in the sample code you mentioned are not available in IC 5.10. If i am running a search of instances to get all the instances of a master-cell i was not sure how i can efficiently traverse the huge hierarchy of a full chip.

    Is there way to search the hierarchy to get all the instantiations of a master-cell and get the hierarchical transform information of the found instance which can be used to calculate the top-level origin-coordinates of that instance? Using the above location information i can write another program to create a new layout and place the instances at those coordinates

    Thanks Srinath
