FinFET model parameter

Saeed Gharagoz
I have a FinFET model parameter and I need to use to simulate a circuit. How can I do it? Should I only change the file extension from .pm to .scs and copy it where everything else is? Or should modify the existing file? And any idea where can I get 22nm MIGFET model? Thanks

  • Hello Andrew,

    Thanks.

    But before doing simulations, I need to integrate a particular  model of a new device like finfet into spectre.

    I found following line in one of the doc about spectre.

    'The Spectre Compiled Model Interface (CMI) option lets you integrate new devices into the Spectre simulator using a very powerful, efficient, and flexible C language interface. This CMI option, the same one used by Spectre developers, lets you install proprietary models.'

    Do you have any idea about this??

    Using Compiled-Model Interface

    The ® Spectre® circuit simulator supports dynamic loading of device models. This feature allows you to dynamically load device primitives (stored in shared objects) at run time. This is useful for developing and distributing models.

    Installing Compiled-Model Interface (CMI)

    CMI is now shipped with Spectre. The installation is done as a manual step after the Spectre product installation.

    To install CMI, run the cmiExtract script located in the following directory:
    your_install_dir/tools/spectre/bin

    You must have a valid Spectre CMI license to run this script. You are prompted to specify a directory in which the CMI hierarchy is to be installed, with the default being your_install_dir/tools/.

    Once the extraction script is complete, the CMI hierarchy can be found in the directory spectrecmi in the specified location. The README files are in the spectrecmi directory and the CMI manual, cmiprint.pdf, is in spectrecmi/doc/. See the CMI manual, Compiled-Model Interface Reference for information on how to proceed.


    Thanks & Regards:
