Model Card

analogy

I have created a model card , but seems like ADE cannot plot output after simulation.Below is my ADE log:

This is what my CDF and library decleration looks like:

When I run ADE simulation, all I get is a blank waveform window.Am I doing something wrong ?

Thanks.

    You didn't say what you were trying to plot, nor show your input.scs (both of which are rather important bits of information) but the above part of the log file gives a good clue as to the problem. If you notice, there are no transistors in your circuit - only a capacitor and two voltage sources. This is because you have defined a subckt, with a model inside, but no instantiation of the model - you'd need an instance of the transistor.

    Typically you'd do:

    inline subckt nmos45 (d s g b)
    parameters w=1u l=1u  // and any other parameters that need to be passed in
    nmos45 (d s g b) nch w=w l=l
    model nch ...
    ends nmos45

    The benefit of making it an inline subckt is that you then can directly plot device parameters or access operating point data for the inline device (the device with the same instance name as the subckt name) as if the extra level of hierarchy didn't exist - without that, it gets more complicated. However,  this is only worth doing if you are doing some kind of transformation of the parameters passed in - if it's a direct mapping, you might as well dispense with the subckt wrapper altogether and simply define:

    model nmos45 bsim4 type=n ...

    and then in your top level circuit you can end up instantiating nmos45 directly with no need to have a subckt.

    I don't know what the "M0D" that it was trying to save was - but it's complaining about that too - maybe related to you instantiating an empty subckt?

    Regards,

    Andrew.

  • In that case the changes I suggested should fix it.

  • Very well.I will try see if it's fixed.Thanks.

  • It seems that back in term mapping I didn't add nil D:\d... , this is what caused specter to generate M0D (I assume).
