problem with mmsim61

Hi Minci,

 This is a spectre error and isn't from the Analog Design Environment.

The first issue that I see is you are using a very very old version of spectre that is no longer supported.  Please consider upgrading to MMSIM 7.2 - there have been many fixes and enhancements in the software.

You may download the latest release from the downloads.cadence.com website.

Best regards,

 Tawna

 thanks,Tawna,but i can use the mmsim61 normally without updating in my work place.

how could i fix this if i dont want to update my mmsim?

It's impossible to diagnose without more information. Maybe you should try taking your input.scs and running from the command line and see if it reveals more information about the root cause.

Potentially there might be some sensitivity to what is in your input.scs, but without seeing that and knowing the precise version of spectre, it's hard to know. Even repeating this within Customer support could be a challenge as the version of spectre you're using is old and unsupported, as Tawna mentioned - but Customer support would do their best to help you (I'm advising that because you may not be able to post the netlist here, and certainly not the model files).

Regards,

Andrew.

 hi,Andrew

when i running the input.scs from the command line,it shows below:

[zxd@zxd netlist]$ spectre input.scs
cpp: unrecognized option `-$'

Internal error found in spectre.  Please run `getSpectreFiles' or send the
        netlist, the spectre log file, the behavioral model files, and any
        other information that can help identify the problem to
        support@cadence.com.

/usr/eda/cadence/MMSIM61/tools/bin/spectre: line 180: 16660 Aborted     /usr/eda/cadence/MMSIM61/tools.lnx86/spectre/bin/spectre input.scs

And the line 180 of the input.scs is:

166      if [ $dplgen -eq 1 ];
167      then
168         args=""
169         for a in $@;
170         do
171         case $a in
172                 \#dpl      ) a="\\#dpl";;
173                 \#ahdlfile ) a="\\#ahdlfile";;
174             esac
175             args="$args $a"
176             shift
177     done
178     eval ${APPBINPATH}/${PROGRAM} $args
179   else
180     eval ${APPBINPATH}/${PROGRAM} "$@"
181   fi
182 else
183   exec ${APPBINPATH}/${PROGRAM} "$@"
184 fi
185
186 EXIT_VAL=$?

 do you know what does this mean?

That's line 180 of the spectre script, not line 180 of the input.scs (at least I hope so). All that says is that the script failed because the executable it launched failed.

Doesn't tell us anything more. Sorry... A testcase would be needed, most likely (at least seeing the input.scs, as I said earlier).

Regards,

Andrew.

Also, the

cpp: unrecognized option `-$'

is a known issue in MMSIM6.1 and is fixed in one of the later ISRs - this was over two years ago.

You really do need to upgrade your version of Spectre.  I recommend contacting Cadence Customer Support on this.  That is the appropriate place to troubleshoot issues like this.

best regards,

Tawna
