ocean -nograph error

nigam214

I am very new to ocean plateform and cadence tool. In my simulation, konsole screen display takes most of the time and I want to disable it. I found that "ocean -nograph" does the same. I am trying to use -nograph option but its not work. I don't get any log or output file. Could you please help me to resolve the issue. Screen log and ocean script is given below.

  • This is covered in sourcelink solution 11494094. You need to install the RPM package gdbm on the machine. For example:

    > rpm -q -f /usr/lib/libgdbm.so.2
    gdbm-1.8.0-26.2.1

    The version number may vary, depending on your OS version.

    This package must be installed for "nograph" modes to work, as it is required by
    the
    Xndx "null" X server.

  • thankyou Andrew. I will try to install this RPM.

  • Hi,

    Has the installation of that lib solved your problem? In my case I still have the same error: 

     *WARNING* Could not locate rgb.txt file in /usr/lib/X11
    *WARNING* This file is required for color operations with the non-graphical
    *WARNING* X server and many WARNING messages may follow this one!
    *WARNING* Unable to open -nograph X Window Display "node03.cluster.ic.unicamp.br:500.1"
    *WARNING* (using "exec /tools/cadence/IC5141/tools.lnx86/dfII/bin/Xndx :0&").
    *WARNING* Xndx output may be found in file /tmp/Xndx<pid>.log

     

    How does I solve it?

     

    Kind regards,

  • The rgb.txt file missing shouldn't be enough to make it exit. More info on that part can be found in Solution 11593064 .

    Did you look at the /tmp/Xndx<pid>.log file? It may have given some more clues...

    Regards,

    Andrew.

  • Hi Andrew,

     

    On the log file it shows the following error:

     

    Couldn't open RGB_DB '/usr/lib/X11/rgb'

    Binding TCP socket: Address already in use

    Cannot establish tcp listening socket: Address already in use

    Trying to connect an existing tcp listening socket...

     

    Any  idea?

    Just to make it clear, I want to run ocean in command line, so I'm calling the program as:

    >> ocean -nograph 

    Regards, 

     

     

  •  It might be that something else is using the port - or that you have too many "-nograph" sessions running on the same machine. 

    You could try using:

    setenv CDS_XNDX_OFFSET 1  # or a number from 1 to 9

    or:

    export CDS_XNDX_OFFSET=1

    (the first is for csh, the second for bash/ksh).

    before running icfb -nograph. Hopefully that will help.

    Regards,

    Andrew.
