    Dear All,
    I want to do the following job:
    I want to place metal contact over the source and drain connections of
    We can do this by leCreateContact().
    But how to determine the number of contacts that has to be placed.
    If there any way to know the number of source/drain contacts of a
    mosfet from the ROD object ID or CDF ID of the mosfet?
    Thanks and regards,
    Lokesh rajendran.

    If I had to do that, I'll use something like the virtuoso toolbox
    (available in XL since .. I don't know) which has a function to
    automaticallly fill areas by the good contacts/ vias.
    I hope that it does not need specific configurations to handle a

    Or use the function dbGetOverlaps to get the active shapes parameters
    belonging to the MOS, then determine how many contacts you need
    knowing their parameters (width, length, layer overlaps ...) .
