NOTES:

   Related logic is defined as being logic that shares connectivity - e.g. two
   LUTs are "related" if they share common inputs.  When assembling slices,
   Map gives priority to combine logic that is related.  Doing so results in
   the best timing performance.

   Unrelated logic shares no connectivity.  Map will only begin packing
   unrelated logic into a slice once 99% of the slices are occupied through
   related logic packing.

   Note that once logic distribution reaches the 99% level through related
   logic packing, this does not mean the device is completely utilized.
   Unrelated logic packing will then begin, continuing until all usable LUTs
   and FFs are occupied.  Depending on your timing budget, increased levels of
   unrelated logic packing may adversely affect the overall timing performance
   of your design.

Section 1 - Errors

Section 2 - Warnings
--------------------

Section 3 - Informational
-------------------------
INFO:MapLib:562 - No environment variables are currently set.
INFO:MapLib:535 - The following Virtex BUFG(s) is/are being retargetted to
   Virtex2 BUFGMUX(s) with input tied to I0 and Select pin tied to constant 0:
   BUFGP symbol "iCLK_BUFGP" (output signal=iCLK_BUFGP)
INFO:LIT:244 - All of the single ended outputs in this design are using slew
   rate limited output drivers. The delay on speed critical single ended outputs
   can be dramatically reduced by designating them as fast outputs in the
   schematic.

Section 4 - Removed Logic Summary
---------------------------------
   2 block(s) removed
   4 block(s) optimized away
   1 signal(s) removed

Section 5 - Removed Logic
-------------------------

The trimmed logic report below shows the logic removed from your design due to
sourceless or loadless signals, and VCC or ground connections.  If the removal
of a signal or symbol results in the subsequent removal of an additional signal
or symbol, the message explaining that second removal will be indented.  This
indentation will be repeated as a chain of related logic is removed.

To quickly locate the original cause for the removal of a chain of logic, look
above the place where that logic is listed in the trimming report, then locate
the lines that are least indented (begin at the leftmost edge).

Loadless block "processor/read_strobe_flop" (SFF) removed.
 The signal "processor/read_active" is loadless and has been removed.
  Loadless block "processor/read_active_lut" (ROM) removed.

Optimized Block(s):
TYPE 		BLOCK
GND 		XST_GND
VCC 		XST_VCC
LUT1 		hc164/hc164_driver_inst/tx_cnt_Eqn_bis_1_rt
LUT1 		hc164/hc164_driver_inst/tx_cnt_Eqn_bis_1_rt1

To enable printing of redundant blocks removed and signals merged, set the
detailed map report option and rerun map.
