Spectre simulation error

CCH01

Hello everyone~
I just install MMSIM7.1 with IC5141_USR6 and try to simulation a simple circuit, but when I finish all settings
go "netlist and run". It stopped at CIW and showed the following message
"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 option 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."

and then I run the runsimulation and get a message
"/usr/cad/cadence/MMSIM/cur/tools.lnx86/spectre/bin/32bit/spectre: error while loading shared libraries: libelf.so.1: cannot open shared object file: No such file or directory"
I don't know how to fix this problem. I probably made some mistakes at somewhere.
Please give me some advise !!

  • # rpm -qa | grep elfutils

    If elfutils is installed, add it to your library path, otherwise refer to this post: http://www.cadence.com/Community/forums/p/14360/24264.aspx#24264 (except search for the shared object you need)

  • Hi tkhan~thank you for your help!!

    I have fixed the libelf.so.1 problem!!

    But, there is another problem when I Exit CIW my terminal windows will show " libgcc_s.so.1 must be installed for pthread_cancel to work", is it ignorable ?

    How can I fix this problem?

    Best Regards

  • The pthread_cancel error is one I have usually seen from people running the Mentor Calibre integration.

    We have an internal solution which says:

    The workaround suggested by Mentor is to add "/lib/i686" into $LD_LIBRARY_PATH.

    If indeed you are using the calibre integration and this does not solve it, you should contact Mentor for support to resolve this.

    Best regards,

  • Hi Andrew~~thank you for your advice.

    Your experience is very useful~~~ 

    I can use the program normally now!!!

    Best Regards

  • Hi,

    I'm trying to run Cadence 5.1.41 Analog environment on CentOS 5.5. I have got the following message error running spectre

    /home/User/Cadence5.1.41/MMSIM7.11/tools.lnx86/spectre/bin/32bit/spectre: error while loading shared libraries: libelf.so.1: wrong ELF class: ELFCLASS64

    Please, could you explain how to fix it?

  •  It's probably just picking up the 64 bit version of libelf.so.1 (which is in /usr/lib64) (maybe you have $LD_LIBRARY_PATH including that directory) but you'll need the 32 bit version of this library. On my machine:

    UNIX> rpm -q -f /usr/lib/libelf.so.1
    elfutils-libelf-0.125-3.el5.i386

    Note that CentOS 5.5 is not a supported distribution and so no testing has been done on it, and no patch data files are provided for it either.

    Regards,

    Andrew.

  •  Yes, you're right.

    I fixed it!

    Thank you

  • Hi tkhan,

    I also have issue with "libelf.so.1"

    "error while loading shared libraries: libelf.so.1: cannot open shared object file: No such file or directory" 

    I dont have "libelf.so.1 inside /usr/lib. Then I did what you have said: 

         # ~> rpm -qa | grep elfutils

         elfutils-0.137-8.22.58

    Does this result means that I have it on my system. How should I add it on my library path? (I'm using SUSE by the way)

    Kindly help me..

    Thanks!!!
