The following 1 signal is selected to use the primary clock routing resources:
C14M_c (driver: C14M, clk load #: 85)
WARNING - par: Signal "C14M_c" is selected to use Primary clock resources. However, its driver comp "C14M" is located at "62", which is not a dedicated pin for connecting to Primary clock resources. General routing has to be used to route this signal, and it might suffer from excessive delay or skew.
The following 1 signal is selected to use the secondary clock routing resources:
RWBank14 (driver: ram2e_ufm/SLICE_82, clk load #: 0, sr load #: 0, ce load #: 11)
No signal is selected as Global Set/Reset.

WARNING - par: The driver of primary clock net C14M_c is not placed on one of the sites dedicated for primary clocks. This primary clock will be routed to an H-spine through general routing resource and might suffer from excessive delay or skew.

*****************************************************************
Info: NBR allows conflicts(one node used by more than one signal)
in the earlier iterations. In each iteration, it tries to
solve the conflicts while keeping the critical connections
routed as short as possible. The routing process is said to
be completed when no conflicts exist and all connections
are routed.
Note: NBR uses a different method to calculate timing slacks. The
worst slack and total negative slack may not be the same as
that in TRCE report. You should always run TRCE to verify
your design.
