TMC-20812: Paths Failing Removal Analysis with Global Routing in Data Path


Violation of this rule identifies removal failing paths that use global routing resources in their datapath. As compared to local routing resources global resources do not allow for delay to be added for removal.


Name Description Type Default Value Min Value Max Value
maximum_removal_slack Reports a violation for timing paths that have a removal slack below the value of this parameter. double 0.0    
to_clock_filter Reports a violation for timing paths that end at a register in a clock domain that matches the value of this parameter. string *    


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>".




Tag Description
