A set_clock_groups or a set_false_path between clocks <clock_name> and <clock_name> overrides a set_max_delay
-datapath_only (refer to constraint position <#> in the
Timing Constraints
window in the Vivado IDE). It is not recommended
to override a set_max_delay -datapath_only
constraint. Replace the set_clock_groups or set_false_path between clocks with point-to-point
set_false_path constraints.
