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.Table of Contents-----------------Section 1 - ErrorsSection 2 - WarningsSection 3 - InformationalSection 4 - Removed Logic SummarySection 5 - Removed LogicSection 6 - IOB PropertiesSection 7 - RPMsSection 8 - Guide ReportSection 9 - Area Group and Partition SummarySection 10 - Modular Design SummarySection 11 - Timing ReportSection 12 - Configuration String InformationSection 1 - Errors------------------Section 2 - Warnings--------------------WARNING:LIT:243 - Logical network plb_PLB_compress has no load.WARNING:LIT:395 - The above warning message base_net_load_rule is repeated 493

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).The signal "plb_PLB_compress" is loadless and has been removed.
