    These are the following warnings i am getting while running.I am using
    spectre7.1 version

    Hi,

    Are you running a corner analysis by any chance ?
    In this case, you need to setup either the following:

    1. in your .cdsenv file:
    spectre.envOpts useAltergroup boolean nil

    2. Or in your .cdsinit file
    envSetVal("spectre.envOpts" "useAltergroup" 'boolean nil)

    The above would instruct the corner tool to run separate simulations
    for each corner leaving away the benefits of altergroup.

    If you are not using a corner analysis then you better give more
    details on what you are trying to achieve.
    BTW, the best way to share your Spectre version is to post the output
    of the following UNIX command:
    UNIX> spectre -W

    Cheers,
    Riad.

    Hi Riad
    Yes Riad i am trying to do corner simulation with alter group.I am
    using spectre Version 7.0.1.053.Even though if i included the above
    command in the .cdsenv file same errors it is showing.The exact
    problem is few cards in the modlfile is not allowing to include in the
    altergroup Eg:statistics.Can you educate me if there is any other way
    to do corner simulation

    Are you doing the corner simulation by running spectre standalone, or through
    the ADE Corners tool in IC5141, or through ADE XL in IC613?

    However, the simplest solution may be just to move to a later version - MMSIM70
    ISR22, and then specify the option:

    myOptions options ignore_unsupported_altergroup_constructs=yes

    in the netlist. If using ADE, this can be typed in at the bottom of the
    Simulation->Options->Analog form, in the "Additional Parameters" field - just
    type in "ignore_unsupported_altergroup_constructs=yes"

    Regards,

    Andrew.
