  2. Selvakumar,

    The best way to start is to download the generic GPDK (Generic Process
    Design Kit) which is given by Cadence free of charge and contain
    most of the functionnalities for a full-custom design-kit.
    This design-kit is intended to show how to implement a full-custom
    design-kit, and this avoid to start from scratch.

    Look at the following web site. This is your starting point :

    I fully agree with this advice. Cadence is improving the generic process
    design kit daily, adding, for example, techfile functionality to support
    Virtuoso Preview, Cadence Chip Assembly Router, Virtuoso Chip Editor,
    Dracula/Diva/Assura verification, UltraSim, Aptivia, NeoCell technology
    data, OpenAccess, Virtuoso XL, Virtuoso Composer, SeismIC, VoltageStorm,

    And, Cadence tests much of its software using chips designed in this
    generic process. These working examples are valuable samples for those
    of you contemplating adding lines to your own technology files.

    I would just like to suggest a simple re-clarification on the
    reputed 'free-of-charge' point.

    While there may not be an overt additional fee for the Cadence generic
    process design kit, it is my understanding that the generic design kit
    is licensed, copyrighted software - to be used only within the license
    agreement signed when your design tools were purchased from Cadence or
    from a Cadence distributor. It's not freeware is my point.

    Of course, for complete details, check with your local sales
    or support representative.

    Good luck
