Problem Title:
M1.4 NGDANNO - Ngdanno fails to properly annotate back to logical
representation.



Problem Description:
For some cases Ngdanno fails to properly annotate back to
logical representation for parts of the design. The physical
(post-mapped) representation is used instead. This can lead
to unknowns for signals that were not resurrected in the logical design. A patch
 is available in M1.4.


Solution 1:

A fix for this ngdanno error is included in the current M1.4 Core
