Insufficient memory available on simulation using inductor

Wonyoung

Hello,

I'm trying to run a transient simulation on a schematic that includes an inductor. It's not an ideal inductor from the analogLib library, but an inductor included in my TSMC process tech. I get the following message whenever I run a simulation with that inductor included in my schematic (even when I only have one single inductor in the entire schematic). FYI, I'm using IC 5.1.41

Fatal error found by spectre during info `subckts'. Insufficient memory available. Internal error found in spectre during info `subckts'. 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. Segmentation fault.

I'm not sure if this is a problem with Cadence or the TSMC PDK. I attached my netlist file with one voltage source and one inductor. I feel the schematic is too simple to use that much memory. Any help in solving this problem is appreciated.

Thanks, Wonyoung

  • Which simulator version are you using? If IC5141, that's rather old - you should use MMSIM72 or MMSIM101 (say).

    Did you try doing what the error said, and report this to support@cadence.com ?

    Regards,

    Andrew.

  • Thanks for your quick reply. I'm a student at a university, and they told me a better way is to make a Cadence Online Support account. I couldn't make the account right away because of some university program policy, so I thought I would post the question here in the meantime. I thought it might be a common issue people face.

  •  OK, but which simulator version are you using? "spectre -W" should tell you, or you should see it in the spectre.out file shown in ADE.

    Andrew.

  • Sorry I forgot to answer that. I'm using IC5141. Maybe I should install a new simulator.

  •  Yes, that would be a good idea. IC5141 is a 6 year old release, and since MMSIM60 (released at the end of 2004), spectre has been maintained in a separate stream - so the version in IC5141 is really obsolete. Most TSMC models will not have been tested with spectre from IC5141.

    So please install a newer MMSIM version and see if the problem remains.

    Regards,

    Andrew.

  • I used IC614, MMSIM6.2 to run a simple transient simulation, and I get the following message.

    ERROR (ADE-3036): Errors encountered during simulation. The simulator run log has not been generated. Possible cause could be an invalid command line option for the version of the simulator you are running. Choose Setup->Environment and verify that the command line options specified in the userCmdLineOption field are supported for the simulator. Alternatively, run the simulator standalone using the runSimulation file in the netlist directory to know the exact cause of the error.

    I tried running ./runSimulation in the netlist directory, and I got the following message.

    runSimulation scripts generated for spectre interactive are not intended to be used for command line. spectre (ver. 5.10.41.071008 -- 10 Jul 2008). Includes RSA BSAFE(R) Cryptographic or Security Protocol Software from RSA Security, Inc.

    Error found by spectre. Invalid command line argument `-maxw'. Use `spectre -help' for more information.

    Could you help me figure out what is causing this problem? Thank you very much in advance.

  • Problem is solved! I googled and noticed that you had answered a similar question before. I'm posting the link here in case someone finds it useful. http://www.cadence.com/Community/forums/p/13755/22031.aspx
