    I am certain there was a thread not long ago regarding suggested method of
    creating and editing logic waveforms and timing diagrams. Can anyone help
    since I can't find it with Google or I was imagining such a post.

    Essentially I want to put some waveforms together for SDRAM timing where
    sketching and editing waveforms are a must!
  2. Chronology Timing Designer is popular
    and good, but not free.

    Timing Analyzer is free, but Dan
    Fabrizio seems to have forgotten to pay his domain registration fee.

  3. Is that page supposed to include mention of a program called 'Timing
    Analyzer' please? I couldn't see it. Or is that the point you're

    I couldn't find the "free" timing analyser and the Chronology Timing
    Designer version seems far to complicated for what I need.

    I wish to produce nothing more than a sort of state diagram for each clock.
    I'm not bothered about things such setup times etc.
  5. I've long wanted something rather similar myself. Essentially I'd like
    to be able to draw a waveform and/or complete a simple dialog, and get
    a PWL text file as output. I did try my hand at developing something
    in Excel, but it started to get too complicated for a non-programmer.
    I'm getting a bit faster at entering the PWL directly, but that
    becomes very error prone when you try to duplicate chunks of a signal
    further along the time axis.

    I can't beleive you posted that.
  7. Not sure why...?

    BTW, how's progress on getting your program working reliably?

    Actually their pricing is outrageous!
    Me neither :-(
    It's nice - but waaay overpriced imho.
    I think you should be ;-)

    I am quite aware of the importance of setup and hold times as any experience
    designer will know to his cost. However all I require at the moment is to
    get the correct sequence and setup and hold times are an unnecessary

    I'm surprised that no one has written a noddy freeware one!
  10. I wasn't able to find a price and sent an email to its distributor.
    They first wanted to get my postal adress for the CD.

    How much is it ?

    What platform are you on? I have VB4 on W2K and Slackware 10.0 Linux,
    with unbelievable development stuff.

    What exactly is it you're looking for? I saw a plastic thing once with
    about a dozen rows of little plastic toggles, like side-by-side slide
    switches, except the knob was a horizontal line, which could be set
    "high" or "low" for each time slot on any of the rows. Maybe they had
    a middle position. Like:
    ___ __ ___________ ______ _________________
    ---- ____ ---_______ ---____ ______

    _________ _____________ ___________
    _______ __________________ ____________

    ___________________________ ________
    _______ _________________________

    and so on.

    I could do something like that with little nodes you could click to
    toggle a time-slot high or low.

    For that matter, you could do the same thing with a text editor that
    has "overstrike" mode. :)

    Good Luck

    Browsing on for some CAD apps I noted some things
    for logic timing/diagramming. Not what I was looking for so I didn't
    give too much attention to them. Make sure to set the require/exclude
    filters right or you'll wade through a lot of unfinished stuff.

    - YD.
  13. A bit of web searching shows that Dan's email address is

    d2fabrizio at aol dot com

    You might like to email him to ask about his product, and what
    happened to his web site.


  14. I got the information by mail now.
    Timingdesigner professional :

    SingleUser version 5291 $ + VAT
    Floating One mile radius 9750 $ + VAT
    Floating One country 14083 $ + VAT

    plus yearly updates
    SingleUser version 1000 $ + VAT
    Floating license 1750 $ + VAT

    Apparently a powerfull package that requires regular use.

    I got a gift of a student version (it cost $200 USD)
    a few years back, and still use it occasionally.
    I never know what a valuable gift my Daughter had provided!

    Evidently, you haven't. That pussy is worth a couple hundred an
    hour, at least, if you dress her up right.

    Good luck, nazi.

    This is a free on-line tool (they also have tools you pay for).

    Yeah, sorry. I was caught up in the election frenzy.

    Yes, this one was out of line, and I apologize.
