Hello

Please go through this report . This is the Design overwie summary of my project and it has REMOVED BLOCK SECTION 5 . Can anyone help me how to avoid this! Or what is the problem in my code?! How to avoid tis optimization.


this is the report....

Number used as a route-thru: 62
Number of bonded IOBs: 66 out of 158 41%

Total CPU time to MAP completion: 6 secs

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 2 - Warnings
--------------------

Section 3 - Informational
-------------------------
INFO:MapLib:562 - No environment variables are currently set.
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.

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

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

Optimized Block(s):
TYPE BLOCK
GND XST_GND
VCC XST_VCC

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

* Slices can be packed with basic elements from multiple hierarchies.
Therefore, a slice will be counted in every hierarchical module
that each of its packed basic elements belong to.
** For each column, there are two numbers reported <A>/.
<A> is the number of elements that belong to that specific hierarchical module.
is the total number of elements from that hierarchical module and any lower level
hierarchical modules below.
*** The LUTRAM column counts all LUTs used as memory including RAM, ROM, and shift registers.





Please help me! How to get rid of the optimization done by removing two blocks of my design..this is needed for me while analysing power!!??

Please help...
 

modular design and xilinx 10.1

Should i give any more details to recognize my problem?

All i need is the query about optimization that removed 2 blocks in my design!?
Please help...
