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.
