    LTspice Question:

    I have a client using LTspice.

    What is the best way for him to import a design from PSpice?

    Would it work if I make my schematic into a SUBCKT that includes the
    device models within the subcircuit?

    Hire a consultant to help you, cheapskate.

    You could say that to everybody who posts here.

  5. Hello Jim,

    Yes this may be OK. LTspice is very compatible to PSPICE
    except for digital devices.
    Why making a subcircuit? Just run the netlist as it is.

    Best regards,

    I suspect that at the level of simulation intended, the digital
    devices ARE analog.

    ALL digital is ANALOG ;-)

    The SW manager at my first employer said that since Max Planck all
    analog is digital ;-)

    Give them the .CIR and .NET files. The .CIR file calls the .NET file.
    LTspice will run the .CIR file without problem if you don't have any
    goofy digital blocks.

    Be sure to give friendly net names to all the points they want to
    probe. Sucks having to search thru the net list for names.

    That's what I sent them while I think about it, and I just got an
    E-mail that they already have it running ;-)

    My first physics professor, who used to refer to a uniform bar as a
    "military saloon", turned us on to the concept of the universe being
    made not of jello, but of grits.

    Analog is digital, and Planck is constant. Go figure. :)

    Digital units all have the tendency to be quantified and constant. Until
    the not so digital stuff strikes. Ground bounce, ringing, crosstalk,
    EMI, magnetic coupling, supply glitches, the sales guy answering his
    cell phone and so on. Then they call on us analog dudes again ;-)

    Yes, but if you can figure out where it is, you will never
    get there in time.
