    I have some Cadence files (provided by a foundry I work with)
    labeled...

    symbol.oa

    As near as I can decipher by surfing, these are "Open Access" files.

    I find all kinds of baloney about "free", but can't locate a viewer.

    What do I need? Where do I go?

    Thanks!

    My first employer used OpenAccess in the 80's but there were never any
    *.oa files.

    Foundries, layouters etc. sometimes use extensions to describe layers. I
    absolutely don't like that but this "habit" is probably the reason why
    Gerber programs eat those files without complaint.

    OpenOffice is quite good but the database part of it isn't. Quite
    incompatible to the rest of the world. It can't even read in my MS-Works
    database files.
     
  5. Gerbers are text files...

    I know. But it's bad practice to call the files gizmo.top, gizmo.a02,
    gizmo.bot and so on. They should be called gizmo_top.pho, gizmo_a02.pho,
    gizmo_bot.pho and so on. That's how professional layouters like mine do it.

    Do the TextFX menu and select Dec to Hex. That'll show the actual
    values.

    Joerg Inscribed thus:
    Nothing other than "Works" can read its database files !

    When I started up a small med company I found that admins in the US were
    largely unfamiliar with databases. They knew Excel well but not Access.
    Same for the one I hired. So, I had to teach her because I wanted just
    about anything organized in databases in order to have the company ready
    for growth.

    I took some sample databases from my home to the company (sans content,
    of course, except for a few lines of sample data). It was all in
    MS-Works. I had no problem at all getting that loaded into MS-Office
    which was the 97-version back then.

    Can Works export its data to some more readable format?

    Thanks,

    If I remember correctly it can do comma delimited, not sure about any
    other.

    Things may have changed a bit since then. I remember rewriting a works
    database application in "Paradox" because nothing could read
    the "Works" format and "Foxbase" cost a fortune at the time. I don't
    recall what that became. Come back "Ashton Tate" all is
    forgotten. :)

    Yep, I have. They provide nothing without a HUGE fee :-(

    Yep, you see, Open Access doesn't mean Open, like Open Source, it
    means that there is a standard that bridges across vendors. See, if a
    start up uses OA in their tools, then, when Cadence buys them, it is a
    lot easier to link them into the tool chains... ;-)

    Yup, they're Open Access files. You need a schematic editor that understands
    Open Access. I'm amazed at the responses: a text editor? Open Office? WTF?

    Have you contacted the fab? What options do they offer?
