Pin Constraint Summary:
64 out of 64 pins locked (100% locked).
The following 2 signals are selected to use the primary clock routing resources:
RCLK_c (driver: RCLK, clk load #: 48)
PHI2_c (driver: PHI2, clk load #: 20)
WARNING - par: Signal "PHI2_c" is selected to use Primary clock resources. However, its driver comp "PHI2" is located at "8", 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 2 signals are selected to use the secondary clock routing resources:
nCRAS_c (driver: nCRAS, clk load #: 9, sr load #: 0, ce load #: 0)
nCCAS_c (driver: nCCAS, clk load #: 8, sr load #: 0, ce load #: 0)
WARNING - par: Signal "nCRAS_c" is selected to use Secondary clock resources. However, its driver comp "nCRAS" is located at "17", which is not a dedicated pin for connecting to Secondary clock resources. General routing has to be used to route this signal, and it might suffer from excessive delay or skew.
WARNING - par: Signal "nCCAS_c" is selected to use Secondary clock resources. However, its driver comp "nCCAS" is located at "9", which is not a dedicated pin for connecting to Secondary clock resources. General routing has to be used to route this signal, and it might suffer from excessive delay or skew.
No signal is selected as Global Set/Reset.

*****************************************************************
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.
