Remove the false_path, set_clock_group
-asynchronous, or set_max_delay -datapath_only constraints
that are applied between the synchronous clocks. If the clocks are expected to be
asynchronous, add an asynchronous clock constraint with the proper synchronization
circuitry for the asynchronous clock domain crossing.
To understand which clock domain crossing is synchronous or asynchronous, follow the clock interaction report.
