Use of DC operating point parameters in calculations and plots

archive

Hi all,

I run a DC sweep simulation on ADE and I would like to plot some of the DC operating point parameters of my schematic (such as vdsat of the transistors, ...)
Moreover, I would like to use these parameters in the calculator in order to make calculations (e.g.: use of vdsat in some calculations).

Does anyone have any idea?

Thks for considering my request.

    This is a very commonly asked question.

    Create a text file (called, say, saveop.scs) with the following contents:

    // include file to save op point data
    save M0:all

    where M0 is the name of the mosfet. See "spectre -h save" for more details on the save statement.

    Then, in Setup->Model Libraries, reference this file (I gave it a .scs suffix so it is interpreted in spectre syntax).

    Run your DC sweep, and then you can access the results via the results browser - or just use an expression such as:

    getData("M0:vdsat" ?result 'dc)

    This will then show vdsat versus the swept parameter.

    The same approach will work if you want to save operating point during a transient - you can always just save the specific op point information by doing:

    save M0:gm M0:vdsat

    for example.

    Best Regards,

    Andrew.
