PCI card design

  1. Hi. i'm willing to design a PCI card for a pentium, in order to
    process 32 bits. Where can I get some information about the inner
    electronics of a PCI and any other thing I would need?

    thanx a lot,
    Marcelo

    Don't go for the 'inner electronics' unless you REALLY need it. Get a
    reference design from PLX and work from there.

    One of the 'things you will need' is some idea of just what you are
    getting into here.

    As others have noted - it's best to use a reference design. I have used
    various PLX parts (they have a nice dual PCIX - Hypertransport bridge)
    and their references are very good.

    if you want straight PCI, then it's nowadays PCI 2.2 [2.3 maybe?]
    (almost obsolete though). You'll need the spec and to get it, you need
    to buy it from the PCI sig (http://www.pcisig.com/specifications)

    I concur with the comment you need to know what you are getting into.
    You'll have to put length match / max length controls on all your lines
    and meet some pretty stringent timing requirements (PCIX is the
    tightest). If that wasn't enough, PCI is impedance controlled to make
    sure it's a reflective system (PCI by definition is not terminated
    except into PCI devices).
    If you are not experienced in this arena, I suggest you step back and
    see if you really need to do it.
    If yes, then start by making sure your design tools can handle the
    design rules so you'll get DRC errors if the requirements (which you
    will have to enter) are violated.

    That's only the start - there's a lot more to it.
    If you are getting the idea we're cautioning you - you're right :)

    Cheers

  5. I really need the inner electronics...
