    If you are a PSpice Schematics User you need to be aware that Cadence
    and EMA-EDA will discontinue support of PSpice Schematics at the 10.05
    Release.

    You will then be forced to use (gag me with a spoon) OrCAD Capture.

    I urge you to contact Cadence and/or EMA-EDA to voice your concerns.

    current white-listed address.)

    You could use LTSpice instead.

    Since it outputs a netlist I've been thinking about making a script to
    convert its netlist output to PADS-2K format. This is mostly just for the
    fun of it.

    I still use the Orcad DOS-386 schematic capture. It does everything I
    want done in creating schematics for making boards from.

    I tried using the Windows Capture program on one project. It refused to
    let me add another sheet to the design until I exited the program and
    restarted it. Later on, it cleverly rewired my circuit putting a wire
    between every posible node pair. It is real junk software.

    BTW: I also tried to layout a board with the Orcad PCB-386 once. What a
    nightmare that program was. I ended up sending the job out and abandoning
    the work I'd done.

    Ever since Cadence bought Orcad, their decline has become a power dive.

  3. Why?

    Resistance is futile.

    It makes no real business sense for a company to continue to support two
    products like this. they aint goanna change their mind on this one

  4. Can you suggest an alternative simulation package for the serious
    electronic designer, Kev? LT springs to mind, but do you know of any
    others worthy of recommendation?

    My fall-back position is a PSpice look-alike that will soon be to the
    market. But everything, no matter look-alike, has a learning curve.

    LTSpice is not general enough nor robust enough for my needs... I earn
    my living with PSpice.

    [snip]
    OrCAD was crap long before Cadence got involved. I used OrCAD under
    DOS. When they tried to make their own windows-like version it went
    straight downhill, and **never** recovered.

    You'd think, since they bought MicroSim, that they would learn what a
    user-friendly schematic tool really looks like, and incorporate those
    features into Capture... not a chance... that company must have the
    highest degree of NIH known to man :-(

  6. Ah Paul, it isn't the similator that's the problem, it is the front end.
    Jim has a copy of LTSpice, but he REALLY, REALLY, REALLY LIKES the
    PSpice Schematics front end. He can continue to use his existing
    Schematics for a while, but if he upgrades to a later version of the
    simulator, he is going to have to manually run the simulations instead
    of running them from Schematics. He, reasonably, would prefer not to go
    through this pain. I fully understand, and sympathize... :-(

    Hi Jim,

    It is pretty doubtful that even dozens of complaints will make them revoke that kind of biz decision. I don't remember any case where that was the case, except maybe automotive where customers were able to cajole manufacturers to continue a line for a few more years. But it almost has to involve the press, so in this case you'd have to get it into EEDesign.

    Other than that it's back to things like DOS OrCAD. That was the most reliable CAD tool I ever used and I might dust mine off and start again. Another option may be Eagle but that's Windows based and the parts editor is not so easy to use in my view. But that program allows you to generate scripts that can do all kinds of stuff, even spit out a netlists modified to whatever Spice wants. Sometimes others write these scripts and then post them on the Cadsoft server. Pretty nice.


    Regards, Joerg

    The non-386 version of Draft did everything needed and was fairly easy to
    learn. The only really weird thing was that the quit menu was where you
    saved your file etc.

    The 386 version of draft could and did use more memory. Other than that
    it was the same.
    I'd always pictured it as a death spiral.

    I think their idea for the macros in the Windows version is really
    cute. You can hook in any visual basic program you care to write so long
    as it interfaces to their stuff just right. If I wanted to write my own
    program, I'd write my own. Give me back the simple key press recording
    please.

    Aaaaaarrrrggghh... this eliminates OrCAD/PSpice as the EDA program I would buy.

    (I've used Capture. I've liked it, just I can't get used to it! :/)

  11. I still use Word 7.0. In 20 years time, why would I want to upgrade?

  12. As you are probably about the furthest away from being a "serious
    electronic designer" in these NGs, what springs to your mind on this
    matter is about as valid as John Travolter's on the correctness of
    Scientology.

    You spelled it wrng agan Kevin. www.travolta.com

    But with a quick glance, I didn't see any links to the scientology.

    Maybe you know in general about the scientology, though? How does it
    compare with atheism?
     
  14. Try "+travolta +scientology".

    e.g. http://www.rickross.com/reference/scientology/scien322.html?FACTNet
    Yep. Its complete crap.

    How does it
    What?

    If you're going to resort to flaming, Kev, at least get the spelling

    Do you have occasion to deal with received attachments
    that are formatted with a version later than that?
    What is your technique then?
     
  17. I never get them.
    I think readers are available, anyway, the sender can convert to text!

    Its a law of diminishing returns. Like, modern music keyboards have
    perfect piano, brass, guitar sounds etc, new stuff just adds redundant
    waffle.

    You should try it again. I'm very pleased with version 9.1 especially
    with the CIS option. But, you should run it on an NT based Windows
    (not 98, ME, etc) and good quality PC hardware.

    [... panning Orcad's Capture ...]
    Perhaps your standards are too low. :)

    Have you ever tried the DOS Draft program? I find it far far easier to
    use than Capture. You use your left hand to poke keys on the keyboard
    while your right hand moves the cursor. It has an auto-pan feature and
    macros which were left out of the Windows one I tried. It also doesn't
    require a special PC with a special OS to run. It will run in a DOS
    window under everything but perhaps XP. I only exclude XP because I
    haven't tried it.

    BTW: DOS Orcad will also run quite nicely under Linux. So I can install
    my own copy at home and work at home or at work with the same user
    interface.

    What is it? When is it due out? Expected cost?
