 | `-repair_tns` | Percentage of violating endpoints to repair (0-100). When `tns_end_percent` is zero, only the worst endpoint is repaired. When `tns_end_percent` is 100 (default), all violating endpoints are repaired. |
 | `-max_repairs_per_pass` | Maximum repairs per pass, default is 1. On the worst paths, the maximum number of repairs is attempted. It gradually decreases until the final violations which only get 1 repair per pass. |
 | `-max_utilization` | Defines the percentage of core area used. |
+| `-max_iterations` | Defines the maximum number of iterations executed when repairing setup and hold violations. The default is `-1`, which disables the limit of iterations. |
 | `-max_buffer_percent` | Specify a maximum number of buffers to insert to repair hold violations as a percentage of the number of instances in the design. The default value is `20`, and the allowed values are integers `[0, 100]`. |
 | `-match_cell_footprint` | Obey the Liberty cell footprint when swapping gates. |
 | `-verbose` | Enable verbose logging of the repair progress. |
