Check the IS_FIXED property of the BUFG instance to find this out. If the IS_FIXED property is set it means that it is locked by user constraints. If this is the case, modify the constraints so that the I/O port and BUFG get placed in same clock region. ...
由于clock region包含多个tile,而tile由site构成,site又由bel构成,因此,已知clock region,可以很方便地找到其下的tile、site和bel。反过来,已知site或tile,可以找到其所在的clock region。但如果已知bel,则不能直接找到其所在的clock region: set all_cr [get_clock_regions] ...

Using the CLOCK_ROOT property lets you manually assign the clock driver, or root to a specific clock region on the target part, and hence manage clock skew. (UG912) Vivado Design Suite Properties Reference Guide states that the applicable objects of CLOCK_ROOT can be either a global clock ...
