Installing graph_log:

  mkdir ${HOME}/bin  # if ${HOME}/bin doesn't exist

  cp graph_log.zip ${HOME}/bin   

  unzip ${HOME}/bin/graph_log.zip

  rm ${HOME}/bin/graph_log.zip



Invoking graph_log:

  If ${HOME}/bin is on ${PATH}

     graph_log <options>

  Else

     ${HOME}/bin/graph_log <options>



Graph_log usage:

Usage: graph_log [-wns] [-tns] [-drc] [-area] [-help]

    -wns         : Xgraph WNS over time

    -tns         : Xgraph TNS over time

    -drc         : Xgraph DRC over time

    -area        : Xgraph AREA over time



   If no -wns, -tns, -drc, or -area options are given, then all are plotted.



Caveat:

graph_log assumes that the compile log format contains a timestamp

in either the 1st or 2nd field. For example:

 ELAPSED             DESIGN                            

  TIME      AREA    RULE COST         ENDPOINT         

--------- --------- --------- -------------------------

  0:03:05  211335.5       5.0 abc_reg/D



If you use a different format, then graph_log will not work.
