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)

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.
