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:
Then I try to run
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?
I'm still having this problem.
Here is a sample log file:

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!
In reply to mbhealy:
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.
