Liberate fails due to wrongly generated command

marten

Hi there,


when we start liberate for the characterization of our standardcell lib, the char_library command fails with this error message:

sh: 1: Syntax error: Bad fd number
LIBERATE - SYSTEM ERROR - could not execute command: cd /home/sachatterjee/subvt_28/SUBVT28CORE_test/lib/altos.vnode3.ks.T20150914115612398704S0023683.0; /sct/homes3/cadence/mmsim-13.11hf252/tools/bin/spectre  +lqt 0 /home/sachatterjee/subvt_28/SUBVT28CORE_test/lib/altos.vnode3.ks.T20150914115612398704S0023683.0/sim.sp >& /home/sachatterjee/subvt_28/SUBVT28CORE_test/lib/altos.vnode3.ks.T20150914115612398704S0023683.0/sim.lis


Obviously, the pipe command " >& " is wrong syntax for sh and maybe it is meant to be run in a bash. How can we force liberate to use bash instead of sh?

Cheers,

Marten

    Hi Andrew,

    I run using "spectre -W" and also using the "spectre -h", with the follow commands:

    set_var extsim_cmd spectre
    set_var extsim_cmd_option -W or set_var extsim_cmd_option -h
    char_library -extsim spectre -ecsm -cells ${cells_list} -thread 1

    But the errors are quite similar:

    - With "spectre -W":

    The first error is:

    *Error** (char_library) :  Cannot find sim.print or sim.measure in dir [/dh_eldorado/projects/pacemaker/workspaces/jacqueline.mertes/cliosoft/data/eldorado_lib/el_char/liberate/rundir/altos.serv175.T20160524163142241290S0002837.0]. This may be caused by simulation error. Check your simulator license and $PATH settings.

    - With "spectre -h":

    The 3 first errors are:

    LIBERATE - SYSTEM ERROR - could not execute command: cd /dh_eldorado/projects/pacemaker/workspaces/jacqueline.mertes/cliosoft/data/eldorado_lib/el_char/liberate/rundir/altos.serv175.T20160524163251419155S0003312.0; /apps/cadence/MMSIM_14_10_459/tools/bin/spectre  -h =log sim.lis  /dh_eldorado/projects/pacemaker/workspaces/jacqueline.mertes/cliosoft/data/eldorado_lib/el_char/liberate/rundir/altos.serv175.T20160524163251419155S0003312.0/sim.sp >& /dev/null

          * Spectre exit code : 2(stop simulation because of Spectre error condition)

    And the fourth error is similar to the first error of simulation with "spectre -W":

    *Error** (char_library) :  Cannot find sim.print or sim.measure in dir [/dh_eldorado/projects/pacemaker/workspaces/jacqueline.mertes/cliosoft/data/eldorado_lib/el_char/liberate/rundir/altos.serv175.T20160524163251419155S0003312.0]. This may be caused by simulation error. Check your simulator license and $PATH settings.

    So, I don't know why the Spectre didn't write some files (sim.measure or sim.print) and this error is propagate through all characterization.

    Now, I'm trying others Spectre options as "spectre +diagnose" and "spectre +debug".

    I have using the command - set_var extsim_save_failed "all" - to can figure out what's happening

    But I don't have any idea what's going on with this characterization.

    Do you have any idea?
