TMC-20712: Paths Failing Recovery Analysis with Global Routing in Data Path


Violation of this rule identifies setup failing paths that use global routing resources in their datapath. As compared to local routing resources global resources are much less flexible during optimizations and incur more delay overhead.


Name Description Type Default Value Min Value Max Value
maximum_recovery_slack A violation is reported for timing paths that have a recovery slack below the value of this parameter. double 0.0    


The associated node on the data path should be demoted to local routing using the QSF "set_instance_assignment -name GLOBAL_SIGNAL OFF -to <instance_name>".
