ELC (Simulation failed with the status 25600)

Hi,

 I am trying out ELC and found one issue, db_spice couldn't pass, output looks like below:

elc>  db_spice -s spectre -p typical -keep_log -keep_wave

   DESIGN        PROCESS       #ID         STATUS     IPDB

-------------+-------------+----------+--------------+-----------

while encounterlc.log/foo.log/*.log says

 Simulation deck created in /home/eda1/ELC/encounterlc.work/foo.work/INVX1_typical_D0000

Using command spectre

Simulation failed with the status 25600

Releasing lock 

the corresponding .lis file says:

Aggregate audit (4:34:48 PM, Thur Jul 24, 2014):

Time used: CPU = 1.17 s, elapsed = 1.17 s, util. = 100%.

Time spent in licensing: elapsed = 798 ms, percentage of total = 68.3%.

Peak memory used = 46.8 Mbytes.

spectre completes with 0 errors, 0 warnings, and 0 notices. 

Seems simulation passed without an issue.

I am really puzzled, could someday let me know what I should do in order to debug this?

I am using ETS10.1 + MMSIM7.2,  haven't found version compatible information in ELC document either.

 Thanks!
