    You simply could do form command line

    spectre –h <component> e.g bsim3v3

    and search for the region parameter.

    For the MOS bsim3v3 models it is

    region=triode   

     Estimated operating region. Spectre outputs number (0-4) in a rawfile.

     Possible values are off, triode, sat, subth, and breakdown.

    Bernd told you precisely how to do this. First find out what model your bjts and mosfets are using - if it was "bjt" then you'd do "spectre -h bjt". If the bjt was using  "vbic", you'd do "spectre -h vbic" and so on (similar for the mosfets). You can see the available models using "spectre -h".

    Regards,

    Andrew.
