    Locked files in Encounter Library Characterizer Reply

    Hi All,

    I am trying to use Library Characterizer and I am getting a very basic error that doesn't make any sense to me.

    I start elc and run the command:
    db_open test_run

    Then I try to run
    db_prepare -f

    and I get the following error:
    [ERROR(db_prepare)]Cannot access the design test_run because it is locked by [user] at Sun Oct 11 18:28:12 2009
    . Use the 'db_clean -lock all' command to release the lock and try again.

    If I run the db_clean line it doesn't help at all. I get the same error. If I delete the lock file: test_run.ipdb/ipdb.tech/lock/IPDB.dblock then elc Segfaults. What could possibly be causing a newly created database to be unaccessible?

    Please help!

    I'm still having this problem.

    Here is a sample log file:

    Here is my elccfg file. I am trying to run spice simulations on the local machine, so I have not started ipsc or ipsd. Is that okay? I would think the error would be different if that were the case. And anyway, I have tried using ipsc and ipsd as well. I still get the same problem. 

     

    Here is also my elccfg file: 

     #Specify the environment variable settings.
    EC_SIM_USE_LSF=1;
    EC_SIM_LSF_CMD=" ";
    EC_SIM_LSF_PARALLEL=2;
    EC_SIM_TYPE="hspice";
    EC_SIM_NAME="hspice";
    EC_SPICE_SIMPLIFY=1;
    EC_CHAR="ECSM-TIMING ECSM-POWER";
     
    #Specify the characterization inputs.
     
    SUBCKT="cells.sp";
    MODEL="allModels.scs";
    DESIGNS="AND2X1 AND2X2";
    SETUP="setup.default";
    PROCESS="typical";

     

    Does anyone see anything wrong with this?? Do I need to try to reinstall elc? Please help!

    It looks like this problem is related to some kind of configuration or installation error. I don't know what it is yet but for some reason elc won't work on a particular set of machines on our network. Other machines seem to work correctly, so for the time being I will be using those. Hopefully we can get it working on the original machines because they are faster.
