I have an xpm_memory_fifo buried inside an axi_smartconnect in my design. In UG974 there are two clocking modes: common clock and independent clock. There is a note in UG974 that states "If CLOCKING_MODE is set to independent_clock, Vivado may trigger a false positive CDC-1 warning and can be ignored." I would like to verify that my design is using the independent clock setting and this warning can be ignored. However, under cell properties in the Vivado GUI the clocking mode is set to 1. Does this 1 correspond to common clock or independent clock?
