Real time: 18 secs Start NBR router at 14:14:36 02/28/21 ***************************************************************** 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. ***************************************************************** 28 potential circuit loops found in timing analysis.
