    You may want to look at 'scale' or 'XScale' utility shipped with IC ; it does precisely that.

    Note that you may have rounding problems when scaling down, so you should really check the results
    carefully.

    Cheers,
    Stéphane

    For more complex cases Cadence has a tool called "Virtuoso Layout Migrate" which
    can handle pcell migration too - if you're porting from one technology to
    another and have to map pcells too.

  5. Is this question related to the rest of the question?

    You can find them all in:

    <ICinstDir>/tools/dfII/etc/tools/*/.cdsenv

    Also there's a file at:

    <ICinstDir>/tools/dfII/samples/.cdsenv

    which lists them all.

    Regards,

    Andrew.
