4.3.11.2.1. SDC Commands
SDC Command | Fitter | Timing Analyzer | Recommended Settings |
---|---|---|---|
set_max_skew 39 | To constraint placement and routing of flops in the multi-bit CDC paths to meet the specified skew requirement among bits. | To analyze whether the specified skew requirement is fully met. Both clock and data paths are taken into consideration. |
Set to less than 1 launch clock. |
set_net_delay | Similar to set_max_skew but without taking clock skews into considerations. To ensure the crossing latency is bounded. |
To analyze whether the specified net delay requirement is fully met. Clock paths are not taken into consideration. |
This is currently set to be less than 1 latch clock. 40 |
set_min_delay/set_max_delay | To relax fitter effort by mimicking the set_false_path command but without overriding other SDCs. 41 |
To relax timing analysis for the setup/hold checks to not fail. 42 |
This is currently set to 100ns/-100ns for max/min. 43 |
