Liberate fails due to wrongly generated command

We found out, that this issue is related to the ubuntu operating system (we know this is not supported...). If someone else is also facing this problem, reconfigure the system shell:

sudo dpkg-reconfigure dash

After choosing "no", /bin/sh should point to bash and liberate should execute as expected.

Hi there,

I have a similar issue:

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.T20160518154102845518S0009680.0; /apps/cadence/MMSIM_14_10_459/tools/bin/spectre  +lqt 0 =log sim.lis  /dh_eldorado/projects/pacemaker/workspaces/jacqueline.mertes/cliosoft/data/eldorado_lib/el_char/liberate/rundir/altos.serv175.T20160518154102845518S0009680.0/sim.sp >& /dev/null

I'm using a Centos plataform and it's already running in a bash.

Anyone can help me, please? Any ideas?

Best,

Jack

So bin/sh is pointing to bash, like this?

ls -la /bin/sh

lrwxrwxrwx 1 root root 4 Sep 14  2015 /bin/sh -> bash

Yes, Marten, I've exactly this:

        ls -la /bin/sh

lrwxrwxrwx 1 root root 4 Jul 25  2015 /bin/sh -> bash

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?

That wasn't what I meant - telling Liberate to run spectre -h or spectre -W is never going to work.

I wanted to know what happens if you run "spectre -h" or "spectre -W" from the terminal (i.e. the same place you run Liberate).

Note, Liberate is not something I have that much experience with, so you almost certainly would be better off going to customer support, I think (I'm travelling too, so can't spend much time on this either).

Regards,

Andrew.

Run from my terminal, I was able to open the Spectre tool correctly using both commands.

Probably I'll looking for the technical support to help me on this.

Thanks,

Jack

Hi,

I am also getting the same error(LIBERATE SYSTEM ERROR-could not execute the command...)

When I ran spectre -W & spectre -h,

its showing----->/mnt/cad /MMSIM131/tools.lnx86/spectre/bin/32bit/spectre : error while loading shared libraries : libreadline.so.5 : cannot open shared object file : No such file or directory.

Please help me on this.

Thanks in advance.

Not sure the error is exactly the same - in this case it's spectre that is failing due to a missing shared library. I suspect the same thing might happen on that machine if you ran spectre directly.

It might be that the libreadline.so.5 library is only installed in 64-bit mode, and so you might be able to fix that by doing:

setenv CDS_AUTO_64BIT ALL

before running Liberate. It's also possible that checkSysConf from the MMSIM131 stream would pick this up (because libreadline is one of the packages that it checks for in that version; of course, this depends on you running on a supported OS too).

Finally, on my machine (a RedHat Enterprise 6.5 machine), the 32bit libreadline shared library comes from this RPM:

compat-readline5-5.2-17.1.el6.i686

So you may need to get that installed.

Regards,

Andrew.
