How to do a plot in Cadence?

Alex Liao

Hi, everytime when I want to print a schematic/ layout view to a file, it always says:

There were no system .cdsplotinit files found.

*WARNING* Plotter configuration not loaded.

 I could not find it in the provided PDK. Instead, I found something interesting. Under the /CMC/tools/cadence/IC5141USR6_lnx86, I found a cdsplotinit (no dot in front) and under /CMC/tools/cadence/IC5141USR6_lnx86/tools.lnx86/plot/samples, I found a cdsplotinit.sample.

 I am sure thoses are something related to the plot function. However I tried to rename them to .cdsplotinit which is required from the warning message and it is still not working. Not a proper plotter can be found.

 

Anyone got an idea?

 

Thanks,

Alex

    Andrew,

     

    I have tried setenv LD_LIBRARY_PATH $CDSHOME/tools/lib:$LD_LIBRARY_PATH

    and  $CDSHOME/tools/plot/bin/plotconfig

    It says /CMC/tools/cadence/IC5141USR6_lnx86/tools/plot/bin/plotconfig: line 10:  3386 Segmentation fault (core dumped) ${PLOT_ROOT}/bin/plotconfigEXE $*
     
    Also I have tried different IC version. For CMOS65nm,  
    with printenv result like this:
    CDS_Netlisting_Mode=Analog
    CDS_AUTO_64BIT=NONE
    LD_LIBRARY_PATH=/lib64:/usr/lib64:/lib:/usr/lib::/CMC/tools/cadence/MMSIM_07.20.109_lnx86/tools/lib

    CMC_CDS_MMSIM_ARCH=lnx86
    CMC_CDS_MMSIM_HOME=/CMC/tools/cadence/MMSIM_07.20.109_lnx86
     
    As can be seen the version is IC 614 which is before IC 616 so I did the LD_LIBRARY_PATH again.
    The   $CDSHOME/tools/plot/bin/plotconfig result is very strange:
    Warning: No type converter registered for 'String' to 'map' conversion.
    Warning: Cannot find callback list in XtAddCallback
     
    These two warnings are nested in recurrance.
     
    So I think more things needs to be checked before run cdsplot.
     
    By the way, what are the better utilities that you mentioned?
    Also, I have double checked menus in the schematic/layout editor, I did not find the mentioned ability to directly export an image from schematic/layout editor. The only way I can see is the 'plot menu' which must be the same way of setting cdsplot.
