ERROR: Place - The global clocks clocks.tclk_2x_90_bufg and clocks.ib_iclk2_bufg are locked into a primary / secondary site pair. It is impossible to route all of the inputs to both of these clocks using the global clock combs. Remember that only one of these clocks may have access to any one quadrant so if these two clocks drive multiple loads on a single-component or drive inputs to multiple components locked into the same quadrant, the nets will not be routable using the clock comb. Please correct this before continuing.
