    Hi,

    Is there any way to get the metal layer associated with via
    independent of technology.

    for example if via name is DFM_M2_M1 I should get the metal layer
    associated with this via ie. M1 and M2.

    Hi,
    Uh, is this even possible?
    As far as I know all vias are defined by their technology, thus we can
    have a via named "Confusing_Owntech_v4" associated with layer metal1 &
    metal2 (the person who does something like this to define a 2x2 via
    array this should be dangled upside-down in a volcano).

    If you dump a technology, there would be the definition of vias in the
    generated ASCII techfile, with their corresponding properties (layers,
    dimensions), so there is a way to access these associated layers.
    Some technology name vias as "via3" or "via34" etc. so I don't think
    it's a good idea to define layers by just their name.

    Best regards,
    I-FAB

    Maybe leGetContactRule() does what you want? Check the manual.
