TMC-20023: Invalid Set Net Delay Assignment


Violations of this rule identify set_net_delay assignments that are invalid. A net delay assignment can be invalid either because there is combinational logic on the path, or because no path is found between the specified "From" and "To" collections. set_net_delay assignments through combinational logic are ineffective because such assignments do not propagate through combinational logic.


Modify the set_net_delay assignment path, or use set_data_delay instead.
Note: Run report_net_delay to get more information.
