Starting router resource preassignment

WARNING - par: The following clock signals will be routed by using generic routing resource and may suffer from excessive delay and/or skew.
   Signal=n141 loads=4 clock_loads=4
   Signal=n5 loads=21 clock_loads=4
   Signal=n137 loads=1 clock_loads=1
   Signal=CLK_c loads=19 clock_loads=3

Completed router resource preassignment. Real time: 37 secs 
Starting iterative routing.

For each routing iteration the number inside the parenthesis is the
total time (in picoseconds) the design is failing the timing constraints.
For each routing iteration the router will attempt to reduce this number
until the number of routing iterations is completed or the value is 0
meaning the design has fully met the timing constraints.
