saving operating point parameters

soathana

Hi all,

using "save N0:oppoint" you can save some info about the operating point of a device.

It there a way to get more parameters using this method, or it is model dependent?

Specifically for BSIM4 I get Ids for example but nothing below that, meaning parameters used to calculate Ids.

Thanks,

Sotiris 

  • Sotiris,

    You should be able to get something like 77 different parameters (currently) from the operating point output for bsim4. If you look in "spectre -h bsim4" you'll see there is a section labelled "Operating Point Parameters" which lists what you can get. There are similar lists for other models(e.g.psp1020, bsim3v3, vbic - take your pick). 

    If you're asking about internal calculations as part of the model equations, then no - only certain parameters are output. There are also some "output parameters" which may also be obtained (these are things like effective widths and lengths, etc).

    Regards,

    Andrew.
