The WEIGHT property is a read-only property that reflects the current weight of the
clock. All clocks have a default weight of 1. To prioritize a timing-critical clock
during the implementation, assign it a weight of two using the XDC
group_path command. It is important to note that a weight of
two can only be assigned to an entire clock group and not to individual timing
paths. The weight of the clock can be queried through the WEIGHT property on the
corresponding clock object.
