ELC : Simulation status : FAIL during db_spice

When I execute step 2 in ELC means spice simulation then find simulation status fail for all #ID as shown below.


Command : db_spice -s spectre -p typical -keep_log -keep_wave

[INFO(db_spice)] Check the encounterlc.log/<ipdb_name>.log/<DESIGN>.log/<DESIGN>_<PROCESS>_<ID>.log file to determine the cause of the failure. The SPICE simulation log file can be found in the /home/raminder/hemal_asic/lib_13_5_16_cp/encounterlc.work/<ipdb_name>/<DESIGN>.work/<DESIGN>_<PROCESS>_<ID>/ directory.

//////////////////////////////////////////////////////////////////

I have checked both the directories. 
----->There is no any warning or error in encounterlc.log/.....

----->But in encounterlc.work/......./typical_D0005_tr.lis has some warnnings like,


WARNING (SFE-30):

Warning from spectre.

Can you help to solve this problem?
Thanks in advance.....

    OK, that doesn't make sense - I can't see how it can pick up a shared library from the SPB installation without knowing something about where to find it. 

    So, can you do the following (in the terminal where you've unset things) and post the results:

    echo $LD_LIBRARY_PATH
    echo $PATH
    which spectre

    (it's possible you have spectre as a wrapper script which is setting LD_LIBRARY_PATH).

    Regards,

    Andrew.
