spectre terminated prematurely due to fatal error.

hTmTech
hello , 
I still have this simulation error message  " spectre terminated prematurely due to fatal error."  with cadence virtuoso
What is the problem ??
thanx

    Error found by spectre during circuit read-in.
        ERROR (SFE-23): "input.scs" 12: PM0 is an instance of an undefined model pmos1.
        ERROR (SFE-23): "input.scs" 17: X0 is an instance of an undefined model f_opAmp.

     

    That explains it pretty clearly. This is why it's worth checking the whole file, not just the last line. You haven't specified your models. From the second one, I'm guessing you're using the (rather ancient) functional library. As described in the documentation for this library, you need to include:

    <ICinstDir>/tools/dfII/etc/cdslib/artist/functional/allFunc.scs

    in your model libraries (Setup->Model Libraries in ADE). Then it will find the definition of f_opAmp. Note however that this library contains very old macro-models which pre-date VerilogA (which is a far more powerful way of modelling behaviour).

    As for pmos1 - this is presumably related to the transistor you are using. I don't know whether this is from design kit or other, or a sample from Cadence - but you also need to locate and reference (via Setup->Model Libraries) the models that this uses. There is a model called "pmos1" in gpdk180 (the 0.18um Cadence Generic Process Design Kit), which you'd get if you included <GPDKinstDir>/models/spectre/gpdk.scs section NN in the model libraries. But I don't know if that is what you're doing. And if you're using gpdk devices, this should be added automatically when you start ADE.

    Regards,

    Andrew.

    Well, if it's the same "premature fatal error" as above, I explained above how to fix it. If it's not the same fatal error, you'll need to provide some details...
