WARNING:Anno:26 - NGDANNO found physical components for which 100 percent
   back-annotation is not possible.  (These components are listed below.)  Some
   reasons these components may not be fully back-annotatable include:
   

1. The logic was replicated during physical mapping.
   

2. MAP was directed to optimize the logic through use of the -oe or -os
   option, or the OPTIMIZE or OPT_EFFORT design attribute.
   

3. The component's configuration implies a more complex delay model than can
   be accurately represented in the original design logic.  An example of such a
   configuration is an XC4000-family CLB containing both carry logic and
   multiple flip-flops.
   

Simulation models for the following components will be constructed from the
   NCD netlist.  Signal names buried within these components will be lost.
