Fill Generation  -  Next Steps  -  Rev 15-Nov-2024

 - The file   aaa_list_of_fills.txt   is up to date
   as of 15-Nov-2024.

 - I need to verify how many  NET_TYPEs  there are in the
   DK design (4 that I know of but maybe its 5)   and
   verify or define:

      the Design Rules for each NET_TYPE that are used
      during normal interactive routing and during the
      default runs of the Design Rules Checker

      and verify or define the Design Rules for each
      Net_Type  that should be in effect during normal
      default Fill Generation.

          Note that 2 sets of Design Rules are actually
          needed for each Net_Type for use during normal
          Fill Generation:  one for Medium Resolution
          and one for High Resolution.

          It may end up that the generation of some Fills
          will require a special set of design rules for
          some Net_Types  just for a given Fill.

 - Once all of that is understood and setup then first
   apply it to the file:  generate_all_fills_on_signal_3.sh

   The  generate_all_fills_on_signal_3.sh  script will be
   the only Fill Generation script file to carry the full
   set of comments   and   it will be the "master source"
   file for the script commands that switch us from the
   normal Interactive Routing and DRC  Design Rules for each
   Net_Type  to the default Design Rules for  Fill Generation
   (both High and Low Resolution)  for each Net_Type.

 - Once the  generate_all_fills_on_signal_3.sh  script file
   is correctly and fully written then use its  (i.e. copy
   is commands for changing the Design Rules  from normal
   interactive routing  --->  Fill Generation  --->  and
   back to normal interactive routing)  for the other 3
   Fill Generation script files that are:

       generate_all_fills_on_signal_1_10.sh
       generate_all_fills_on_signal_11.sh
       generate_all_fills_on_signal_12.sh
