Failed to do clock region partitioning

When I compile project in vivado, it prompts:"ERROR:[Place 30-678] Failed to do clock region partitioning:Could not expand clock partition for net clk_wiz/inst/clk_out1 to have enough capacity for type LUTRAM." The following is details:

ERROR:[Place 30-678] Failed to do clock region partitioning:Could not expand clock partition for net clk_wiz/inst/clk_out1 to have enough capacity for type LUTRAM. Net has 525168 loads of this type, but the total capacity in the partition is 459360, over-utilization of LUTRAM may dut to bloating.

Resolution: try removing the area constrains set on the clocks ( sources and/or loads ) that complate for resources in the same clock regions. In case an area constraint on the clock loads is necessary, please either extend the area constraint to cover the clock source, or make sure that the clock source is constrained/placed in a clock region in the same row or column as one of the regions in the specified area constrains. Also try reducing the amount of clock resources in your design, by either combining some clock nets or by changing the placement of clock primitives to reduce the distance between the source and loads of each clock net involved in the area with higher clock routing utilization.
