    Does someone know a process design kit that works FINE with virtuoso
    6.1? The ncsu 1.6 has a lot of bugs and limitations. I'm talking about
    a design kit that has the same resources that gpdk090 and gpdk180
    have. Does someone know how to get the Generic StdCell lib 090 and 180
    (gsclib090 and gsclib180) ? Thanks in advance.

    What is the ncsu 1.6 and gpdk090, or maybe I should ask whose are
    those or where do those pdk's come from? Don't the foundries provide
    for that? I remember MOSIS had certain resources for the universities.

    Every foundry provide a design kit. This is the most basic thing to
    make possible to design a chip. But, when Cadence upgrade Virtuoso
    from 5.1 to 6.1, they change the design database type: cdb to OA.
    OpenAcess is a database type that aims to ease the sharing of data
    between softwares of diferent vendors. But the foundries did't upgrade
    they design kits yet. I heard about TSMC and the HIT-KIT for 0.35um
    are being upgrated.

    NCSU is a free design kit provided by North Carolina State University
    to the processes that MOSIS provide.

    GPDK090 is a cadence proprietary "generic" design kit. Generic means
    it is not applicable to any process. It exists for learning purposes
    only.

    Hi Taimur,

    In an industrial context where chips are designed to make money, the
    foundry/process/Pdk is something we think about before starting any
    development. We can't just ask to move with another foundry when some
    bugs in the flow are encountered :-( I understand this is not a
    problem when you design Soft chips/Ips in case of a University
    projects when generic PDks could be used.

    Well, What I would like to advice is rather to report these bugs/
    limitations to your PDK provider. I'm pretty much sure they will be
    doing their hardest to make it working fine for you. That's the best
    way of improving things. Switching PDKs/Vendors, even in a Scholar
    context, is not the ideal solution since you'll waste a bit of time in
    porting your already designed blocks which is not that easy ...

    And BTW, I have never ever known a bug-free PDK, please let me know
    should you find someone ;-)

    Good luck anyway
