Starting router resource preassignment
WARNING - par: The driver of primary clock net PHI2_c is not placed on one of the PIO sites dedicated for primary clocks. This primary clock will be routed to a H-spine through general routing resource and may suffer from excessive delay or skew.
WARNING - par: The driver of secondary clock net nCRAS_c is not placed on one of the PIO sites dedicated for secondary clocks. This secondary clock will be routed through general routing resource and may suffer from excessive delay or skew.
WARNING - par: The following clock signals will be routed by using generic routing resource and may suffer from excessive delay and/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.
