linear fit of simulation results

olalivier
In ADE I extract some parameters from a waveform (time elapsed from rising to falling edge on some kind of TOT) on a parametric simulation. I plot the result but I would like to get a linear fit of this curve plus residuals. I can't find a way to do that with in the calc. Can you please tell me if that fonction exists. Thank you very much Olivier

    I suspect most people doing this have just done it externally rather than wanting to repeatedly do it in ADE. To me it seems an entirely reasonable request, but we have to prioritise what people actually ask for, of course... otherwise it's so easy to develop features that we think people want and then find nobody in practice is using it.

    I'll put this on my list of things to put together when I have a spare moment (unfortunately it's quite a long list!)

    Regards,

    Andrew.

    Hello Andrew

    Any news on this particular feature?

    I've been missing such a feature as a linear fit to datapoints, meant for extracting muCox and threshold voltages. 

    But as you suggest, it's not entirely too hard to write one yourself.


    Best regards

    Hi Jacob,

    Strangely enough I wrote some code to do this less than two weeks ago - as I said in this other post (where you can find the code), I knew it had come up in the past (I'd lost track of where though...)

    I also published it as an article on Cadence Online Support and it's been added to the Custom IC Calculator SKILL Function Library.

    Regards,

    Andrew.
