    I'm trying to edit a schematic using PADS Logic. It won't let me edit
    a net name. If a name is something like $$$1234, and I click it and
    try to edit the net to anything else, the net name in the dialog box
    is grey and can't be changed. I can add an offpage connector, then a
    new name, but if I delete the offpage, the net reverts to a stupid
    $$$nnnn type name.

    Anybody know why?

    And in the older versions, I could double-click along a connection and
    pop up a new visible net name, and leave it there in plain sight. I
    can't seem to do that now.

    The behaviour is somewhat bizarre. If you select a net segment that joins
    onto a component, PADS will let you assign a visible name to that net. If
    you select any other segment on the same net, or use 'select net', it won't.
    Logic it ain't.

    I am using the PADS 2004. I couldn't edit the name of the net. It just
    allows me edit the net of POWER and GND in the Logic.

    Why you have to edit the name??? In the PADS PowerPCB , you could edit
    the name of the net.
  5. The net names text is associated with pins on components. You need to click
    on a connection segment that is closest to one of the components, and then
    you can edit the net name. You can also check "add net name". Then, you can
    move and rotate the net name to another location along the net. I am still
    using PowerLogic 5.0 here, and PADS Logic 2004SP2 (or maybe 2005SP1) at
    another location and this seems to work.

    A better forum for questions like this is, where there
    is a lot of discussion about problems in newer releases.

    Is that the one with Austen on it?

    There's sure some pissed off people about the 30 year lease (for PADS) they
    bought and the 1.5 (IIRC) year they got.

    Wow, does PADS time out or something?

    Oh, I found the problem. You have to first click the "query mode" icon
    at the top, the blue circle with the "i" inside, or else the
    change-netname dialog appears, but won't work.

    I normally draw my schematics in pencil, on d-size vellum, and leave
    the cad stuff to my drafting guy, but we have a rush job so I'm
    working on this stuff on weekends.

    Yes, apparently.

    You only "rent" it. You don't buy it. It stops working after the time set in
    the License file.

    It used to be (IIRC) that you could purchase a 30 year license period,
    essentially "buying" it. Then some people noticed that when their P.O. said
    the 30 year period and Mentor accepted it they were getting a License file
    with 1.5 years. Apparently Mentor bought PADS a while ago and changed how it
    is sold. I don't know how many, if any, new License files you get for the
    same Purchase. Near as I can tell no one else can figure that out as well.

    Yikes! Sounds like they GenericCad/Autocad thing all over; buy it,
    kill it, force the customers to go upscale.

    I think I mentioned this before....

    A number of years ago a client loaned me a copy of HSpice (in the days
    before PSpice could handle BSIM3v3).

    Midway through the project the license timed out.

    So the oldest son wrote a "wrapper" around HSpice.exe:

    The wrapper, at opening, changed the system date to a date where the
    license was valid.

    The cute part occurred on closing: System date was changed back to
    the current date and all files created during the session had their
    dates changed to current date as well.

    These days such a simplisitic approach is pretty unlikely to work. Mst EDA
    companies these days go to using a commercial license manager such as FlexLM
    which -- although people can and do manage to crack it -- is sophisticated
    enough that the average Joe isn't going to be able to circumvent it. (In
    fact, much of what you see these days are people simply spoofing license
    files -- often far easier than changing, e.g., the license daemon. This has
    unfortunately created a return to the days of a dongled license server,
    although at least with USB dongles hardware compatibility problems are nowhere
    near as bad as they were with parallel port dongesl.)
