[Place 30-574] Poor placement for routing between an IO pin and BUFG. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override this clock rule.

Clock Rule: rule_gclkio_bufg
Status: FAILED
Rule Description: An IOB driving a BUFG must use a CCIO in the same half side (top/bottom) of chip as the BUFGSCL_IBUF_inst (IBUF.O) is locked to IOB_X0Y91
SCL_IBUF_BUFG_inst (BUFG.I) is provisionally placed by clockplacer on BUFGCTRL_X0Y0
