Starting router resource preassignment Completed router resource preassignment. Real time: 1 mins 23 secs Start NBR router at Sat May 23 22:29:51 EEST 2026 ***************************************************************** 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. ***************************************************************** Start NBR special constraint process at Sat May 23 22:29:52 EEST 2026 Start NBR section for initial routing at Sat May 23 22:29:53 EEST 2026 Level 1, iteration 1 15(0.00%) conflicts; 12027(75.23%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.939ns/0.000ns; real time: 1 mins 26 secs Level 2, iteration 1 13(0.00%) conflicts; 11974(74.89%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.933ns/0.000ns; real time: 1 mins 27 secs Level 3, iteration 1 608(0.05%) conflicts; 4391(27.46%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.875ns/0.000ns; real time: 1 mins 33 secs Level 4, iteration 1 689(0.06%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.864ns/0.000ns; real time: 1 mins 38 secs Info: Initial congestion level at 75% usage is 0 Info: Initial congestion area at 75% usage is 0 (0.00%) Start NBR section for normal routing at Sat May 23 22:30:06 EEST 2026 Level 1, iteration 1 122(0.01%) conflicts; 677(4.23%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.864ns/0.000ns; real time: 1 mins 39 secs Level 2, iteration 1 46(0.00%) conflicts; 779(4.87%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.864ns/0.000ns; real time: 1 mins 39 secs Level 3, iteration 1 178(0.02%) conflicts; 545(3.41%) untouched conns; 0 (nbr) score; Estimated worst slack/total negative slack: 0.864ns/0.000ns; real time: 1 mins 40 secs Level 4, iteration 1 446(0.04%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 41 secs Level 4, iteration 2 241(0.02%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 43 secs Level 4, iteration 3 103(0.01%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 43 secs Level 4, iteration 4 58(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 44 secs Level 4, iteration 5 35(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 44 secs Level 4, iteration 6 16(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 45 secs Level 4, iteration 7 9(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 45 secs Level 4, iteration 8 5(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 46 secs Level 4, iteration 9 5(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 46 secs Level 4, iteration 10 2(0.00%) conflicts; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.830ns/0.000ns; real time: 1 mins 47 secs Level 4, iteration 11 0(0.00%) conflict; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.783ns/0.000ns; real time: 1 mins 47 secs Start NBR section for setup/hold timing optimization with effort level 3 at Sat May 23 22:30:15 EEST 2026 Start NBR section for re-routing at Sat May 23 22:30:19 EEST 2026 Level 4, iteration 1 0(0.00%) conflict; 0(0.00%) untouched conn; 0 (nbr) score; Estimated worst slack/total negative slack: 0.783ns/0.000ns; real time: 1 mins 51 secs Start NBR section for post-routing at Sat May 23 22:30:19 EEST 2026 End NBR router with 0 unrouted connection NBR Summary ----------- Number of unrouted connections : 0 (0.00%) Number of connections with timing violations : 0 (0.00%) Estimated worst slack : 0.783ns Timing score : 0 ----------- Notes: The timing info is calculated for SETUP only and all PAR_ADJs are ignored.
