    So there I was thinking that I like the look of these devices (EPAD
    MOSFETs) so I thought I'd go and download the spice models and have a
    play, but alas I couldn't find any anywhere.

    I contacted Aldinc and requested models and they replied asking for my
    company details, my fax phone number and web-site, wife's mobile
    number etc. and said I would have to fill in an NDA!

    Is this normal today? I though that vendors would be only too willing
    to propogate spice models for the devices they provide but it seems
    that I'm being a little naive.

    I'm not sure if I can tweak ordinary MOSFET models or not - anyone
    know? I don't need 100% accuracy, just a nominal fit.

    No, it is not really normal. Just tell them "No thanks, I will just
    use some other part."; and see how they respond.

    I didn't think so. I've already got back to them saying as much but
    they haven't responded. There must be something in the Spice models
    which isn't apparent in the data sheets otherwise they would have
    nothing to lose. I can manage without the models anyway but it's just
    inconvenient not to be able to plant them into my intended circuit.

    If you, or someone you work with, has the time, tools, and expertise
    it is relatively straightforward to derive a decent model from
    measured device parameters. A curve tracer and a LCR meter are
    pretty well required.
